Empire Electric Corporation will not pay legitimate debts owed by evansinv on 2/7/2018

1 out of 5 stars
 

In January 2017 our company (ATS) sold over $20,000 of product to Empire Electric Equipment in Sacramento, CA. We have received a fraction of the amount due totaling $10,000.00 from Empire Electric Equipment in payment. Hours and hours over many months have been spent trying to collect the money rightfully owed to us. Empire Electric Equipment sold this product to a municipality and materials were drop shipped directly to the municipality, confirming Empire Electric Equipment has been paid for the product. We received $3,000.00 on July 5, 2017, $3,500.0 on December 1, 2017 and $3,500.00 on December 27, 2017. It has been over a year and we are still fighting for over half of the money they owe us. Empire Electric Equipment has also accrued approximately $3,400 in late/finance/collection/attorney fees. Empire Electric Equipment has acknowledged time and again in emails, telephone calls and through their full time retained attorney that they owe the money. We have been contacted by other companies that have sold to Empire Electric Equipment with the same issues and all are trying to collect the monies due to them. Empire Electric Equipment simply refuse to abide by the terms that THEY set forth when the product was bought. I would exercise extreme caution if you chose to do business with Empire Electric Equipment!

LED SITE (PARKING LOT) LIGHTING by Stewart on 12/3/2017

CBEA Member
Opportunities and Benefits
CBEA members play an integral role in
the development and application of the
CBEA LED site lighting specification.
They identify candidate products, review
product laboratory testing, conduct field
demonstrations, evaluate candidate products,
and assist with the development of
LED parking lot lighting performance
specifications to guide the design and
purchase of LEDs for parking lots.
Public and private entities are increasingly
utilizing parking lot lighting systems that
meet the CBEA site lighting specification.
This specification saves 50% or more
energy, compared to typical parking lot
lighting systems. Some early adopters
include Walmart, Lowe’s, and Cleveland
Clinic. Walmart is now using lighting
that conforms to the specification in all
new parking lot sites, with over 300 sites
in design or completed to date. Both
Walmart and Lowe’s report energy
savings of 58% compared to ASHRAE
Standard 90.1-2010 (for LZ3).
Overview of the
CBEA Specification
The CBEA Lighting Project Team developed
a performance specification to maximize
the benefits of converting to SSL
technology from the traditional highintensity
discharge technology. The specification
provides information about both
the luminaire and how the site should be
lighted. Lighting designers, engineers, or
SSL manufacturers ideally will work with
commercial building organizations (e.g.,
large retailers or commercial developers)
to provide lighting solutions for different
locations. Key details of the specification
include the following:
• Luminaires backlight, uplight, and glare
(BUG) rating should be characterized
per IES TM-15.

• Luminaires should carry a five-year
warranty covering the luminaire, finish,
and power supply
• Testing requirements are identified
• Different amounts of light (illuminance)
are needed for different parts
of the parking lot
February 2012
• Both power density and illuminance
requirements are by lighting zone (LZ);
different environments need more or less
light (and thus use power differently).
Refer to Table 2 for more information
on basic power density and illuminance
requirements.

Overall Lighting
System Efficiency
Very efficient because of LED directionality, meaning nearly 100% of
light leaves the luminaire
Life Expected long life (50,000+ hours) but actual end-of-life
performance not completely understood
Maintenance Very low maintenance expected due to long life and durability
Environmental
(Mercury)
Contains no mercury
Light Output
Depreciation
Low lumen depreciation rate
Lighting
Uniformity
Directionality and flexibility make maximum/minimum uniformity
ratios below 10:1 easily achievable
Dimmability Fully dimmable
Durability Solid-state technology is much less fragile and less susceptible to
vandalism, breakage, or damage from high winds and vibration
Light
Pollution
Easy to reduce light pollution effects due to inherent directionality
of source.

Energy efficiency and clean, renewable energy will mean a stronger economy, a cleaner
environment, and greater energy independence for America. Working with a wide array
of state, community, industry, and university partners, the U.S. Department of Energy’s Office of
Energy Efficiency and Renewable Energy invests in a diverse portfolio of energy technologies.

A CBEA Project Team is focused on
making reliable, energy-efficient,
and competitively priced outdoor
LED lighting systems more widely
available in the marketplace.
Members of the CBEA Lighting Project
Team are working to support the increased
use of high-efficiency LED parking lot
lighting that is reliable, energy efficient,
and competitively priced. LED technology
is becoming more common as a practical
solution for parking lot illumination. The
potentially long life of LED products defers
the cost of maintenance. Additionally,
LEDs can provide more uniform illumination
than other lighting technologies.
Some of the many benefits for LED
lighting in parking lots are shown in
Table 1 on page 2.
DOE’s CBEAs are focusing on reducing
commercial building energy costs and
consumption by working with a host of
industry suppliers, including appliance,
heating, cooling, and lighting manufacturers,
to meet members’ energy-efficiency
needs. One area in particular that offers
immediate returns is lighting, because the
performance of high-efficiency lighting
systems using solid-state lighting (SSL).

This DOE-sponsored effort is being implemented by the Pacific Northwest National
Laboratory (PNNL) in coordination with CBEA members. DOE actively supports
research and commercialization of LED lighting through its SSL program, which
focuses on research and development, product testing, technical information development,
product demonstrations, and outreach to energy-efficiency program administrators.

DOE provides technical assistance in support of this specification project, including:
• Product demonstration technical support
• Analysis of energy cost savings
• Analysis/quantification of maintenance cost savings
• Investigations into life measurements and other performance indicators
• Development and maintenance of the CBEA product performance specification
• Performance specification technical assistance as needed.

LED Performance by lacommerciallighting on 12/3/2017

5 out of 5 stars
 

Save energy
LED light engines use 30-60% less energy than other
light sources, with no loss of light output, which
represents considerable cost savings as well as major
reductions of greenhouse emissions. Furthermore, LED
technology allows designers to create fittings that utilise
light far more efficiently, delivering light uniformly and
only where it is needed, with minimal glare.
Long life
With 50,000 hours of life, LEDs can last up to 4 times
longer than other light sources, which means reduced
maintenance costs. During the life of an LED luminaire
a comparable metal halide fitting would be relamped
four times. Electrical gear on an LED system may need
servicing as little as once during this time.
Colour performance
LED light engines provide light quality that is second to
none, with a CRI value of over 70 that yields high quality
colour rendering. This enables realistic colours to be
seen when objects are lit at night - a big advantage for
architectural and security lighting. And, importantly,
colour quality is maintained right to the end of the
LED’s rated life.
Environment
LEDs require less material to manufacture them and
their extended life means far less frequent replacement.
And when it finally comes to disposal, the hazardous
waste considerations of mercury-free LEDs are far fewer
than with other light sources.
Light pollution is also greatly reduced, as the superior
optics of LED fittings means light goes only where it is
required. LEDs are also more controllable, with ‘instant
on’ switching and dimmability.
The outdoor environment is
complex and demanding for
lighting. Not only are there the
physical demands of weather and
the city environment but outdoor
luminaires must also perform as
efficiently as possible to reduce
energy use and keep publicly
funded costs as low as can be
achieved. Furthermore, outdoor
lighting must provide a safe and
secure night-time environment in
cities that operate 24/7.
LED lighting, together with careful
product engineering, is GE’s biggest
ally in meeting these needs. It is a
solution that has been developed on
four levels – the four dimensions of
LED efficiency.
LED outdoor lighting systems from GE are designed as
a long term commitment to efficiency and
low maintenance.
By creating products that are versatile and have a wide
range of applications, GE’s engineers ensure that they
will deliver efficient service, wherever they are used.
GE LED light sources enable the design of highly efficient
optical systems that only light the desired area. The less
precise control of larger, non-LED light sources often
results in light spillage.
Also, the extreme long life of the LED light source –
typically 50,000 hours - drastically reduces the time and
cost of maintenance compared to other light sources.
• Variety of light sources
• Long life for low maintenance
• Light is distributed only where it is required
• Full compliance with EU standards

Empire Electrical Equipment does not pay legitimate bills owed! by paul on 11/27/2017

1 out of 5 stars
 

*** update to original post/review Empire Electric Equipment Corp does not pay legitimate bills owed *** In October 2017, Empire Electrical Equipment Corp had agreed, through their 3rd party debt settlement company, to make equal monthly payments starting Nov 20th 2017, to come current within 8 months. However, when Nov 20th got here, yep, you guessed it, no payment made. Also, Mike Garcia with Empire told his debt settlement company he would now not pay unless all of the true and accurate negative reviews were removed. We offered to remove this information once we were paid, but not until we were paid in full. According to Empire’s debt settlement company, that was not acceptable.
Please be very cautious doing any business with such an unethical company that does not pay their honest debts even though they are paid by their municipality customers. Also beware of any credit checks you are performing on Empire. If you are considering doing business with Empire, feel free to use us as a credit reference and we will provide accurate and honest history!

Review of understanding Lighting Controls by oaktownelectrical on 10/26/2017

5 out of 5 stars
 

ighting controls are devices and systems that regulate the output of lamps and luminaires. They either turn the lights on and off using a switch or adjust light output using a dimmer. Growing demands for energy savings and flexibility to support visual needs have given lighting control much greater prominence. In particular, commercial building energy codes are driving demand for more sophisticated, detailed and layered control systems. The digital revolution in lighting control technology has enabled manufacturer solutions to keep pace with these demands.?

A good lighting design requires a good controls design. A good controls design, in turn, ensures that the lighting system produces the right amount of light where and when it is needed. Benefits of a good control design include reduced energy costs and flexibility, which can support the user’s visual needs and create a desired mood or ambience. This article provides a brief introduction to how lighting controls work, resulting control strategies and how those strategies are applied to projects.?

A lighting control device or system operates on an input/output basis. An input component or device provides information to a lighting controller. Based on its logic circuit, the lighting controller decides if and how to change output and subsequently signals the power controller. The power controller then makes any required changes to the output of the controlled lights. These functions may be integrated within a single device or enacted as a series of devices that are rated as compatible. The basic inputs are manual or automatic while the basic outputs are dimming and switching.?

Manual controls require a person to interact with them. Because the user initiates the control action, it is typically driven by applications involving output being adjusted based on a desire to achieve certain visual conditions. A good example is a meeting space where the lights may be raised to full during face-to-face discussion but lowered in part of the room for an audio/video presentation.?

With automatic controls, the input is a signal automatically produced by another component or device, such as a computer, occupancy sensor or photosensor. These components and devices generate signals typically based on time, occupancy or light level. Automatic control is generally driven by energy management, that is, saving energy by reducing or turning off the lights in response to conditions such as lack of occupancy or abundant daylight.?

In both cases, the outputs are switching and dimming. Switching may be enacted as simple on/off, though a degree of flexibility may be gained through bilevel or multilevel switching. This allows a choice of two or more output levels from the luminaire or lighting system (in addition to no output) by assigning alternate lamps, ballasts or luminaires to different control outputs. For example, a three-lamp fluorescent luminaire may be configured with a ballast that controls the outboard lamps and another ballast that controls the inboard lamp, resulting in a choice between outputs of 0 percent (off), 33 percent (one lamp on), 66 percent (two lamps on) or 100 percent (all lamps on). Switching is a simple, relatively economical control method well-suited to applications where a limited range of light-output levels is acceptable and where abrupt, noticeable changes in light level will not be irritating or disruptive. A simple example is a device that automatically turns the lights off (or reduces light output) when a space is unoccupied.?

Dimming may be continuous or step. Continuous dimming enables light output adjustment across a range, with smooth transitions between each output level, resulting in a very high degree of flexibility to satisfy visual need. It is ideally suited to applications where we need transitions between light levels that are not irritating or disruptive to users. Daylight harvesting in an open office is a good example of where continuous dimming is advantageous. As daylight levels rise and fall, electric light levels fall and rise to maintain a constant light level, thereby saving energy.?

Step dimming typically involves one or several output levels with the transition either being abrupt, as in switching, or a smooth fade. Step dimming is well-suited for applications where we want a smooth fade to a preset output level, such as for demand response. It also works for bilevel switching but without changing out alternate ballasts, lamps and luminaires. A good example is light-level reduction in an HID or induction luminaire during times when the space is unoccupied.?

These inputs and outputs can be combined to achieve unique lighting control strategies suited to addressing visual needs, energy management needs or both. Manual control is fairly well understood, so we’ll focus on automatic control. Typically, with automatic control, lighting is reduced to save energy in response to occupancy, a time event or daylight level. Manual and automatic control strategies can be enacted using the same control system by networking controllers with multiple input devices.?

Occupancy sensing: This proven strategy involves reducing lighting use during periods when a space is unoccupied, saving energy by minimizing waste, using occupancy or vacancy sensors. The Lawrence Berkeley National Laboratory’s (LBNL) best estimate of average lighting energy savings is 24 percent.?

The input for “on” operation may be manual (manual-on occupancy sensor or vacancy sensor), automatic (occupancy sensor) or both (auto-on to 50 percent output). The input for “off” operation is automatic; following a designated period of time after the sensor detects a lack of occupancy, it turns the lights off. However, a manual-off override option may be available.?

The output may be switching or dimming. In interior applications, typically the lights are turned off, though for applications that are intermittently occupied, the lights may be switched (e.g., two fluorescent lamps in a stairwell luminaire) or dimmed (e.g., continuous dim to off in an overhead luminaire in an open office or step dim to a lower level for a high-intensity discharge parking-lot luminaire).?

Occupancy sensing is highly suited to smaller, enclosed spaces that are intermittently occupied, such as private offices, classrooms, conference rooms, copy and break rooms, restrooms and other spaces. It is also frequently applied to parking lots and area lighting applications, wallpacks, stairwell luminaires, warehouse aisles, and lighting within or over workstations in open offices.?

Time scheduling: This proven strategy involves reducing lighting use during times of the day when illumination is predicted to not be needed. The LBNL estimates average lighting energy savings of 24 percent (lumping it in the same category as occupancy sensing, though it is arguable that occupancy sensing typically results in higher savings by being more precise).?

The input for “on” may be manual or automatic, while the input for “off” is automatic, usually combined with a manual on/off override. The automatic input is typically a signal from a physical timeclock, timeclock software intelligence built into a control system, or some other building system, such as a building automation or security system. The output may be switching or dimming, depending on whether some light is needed during unoccupied periods or whether the light source cannot return to full output quickly.?

Time scheduling is suited to larger, open spaces that are regularly occupied and spaces that are intermittently occupied but where the lights must remain on all day for safety/security purposes. Local override (time extension) manual wall controls are often installed to allow for irregular use of the space.?

Another method related to both time scheduling and occupancy is the timer switch, which turns off the lights if a set period of time passes after a person enters a room. This type of control device is suited to applications such as utility and storage closets.?

Daylight harvesting: This strategy involves raising or lowering output to maintain a set light level based on daylight contribution. As daylight rises and falls, the electric lights lower and raise to save energy and provide a consistent light level. Due to the variability of daylight, this strategy can be more complicated to apply to spaces, but lighting energy savings average 28 percent, the LBNL estimates.?

Input and output are automatic, though it’s arguable that separately zoning lights near a daylight aperture to a manual switch could be considered daylight harvesting as well. The input measures daylight (open loop) or a combination of electric and daylight (closed loop) using a light sensor. The output may be switching or step-dimming (typically in spaces where switching is less likely to be disruptive, such as in circulation areas) or continuous dimming (typically in regularly occupied spaces with intensive tasks).?

As one might anticipate, daylight harvesting is suited to areas adjacent to windows and clerestories and under skylights and roof monitors—wherever outside light is abundant and consistent.?

Other strategies: Other options include demand response (reducing lighting during certain times of day or in response to a utility request during an emergency grid event) and institutional task tuning (reducing lighting by task areas across a large space designed to a single light level). The LBNL estimates task tuning saves an average of 36 percent lighting energy. The LBNL further estimates that combining any of the above control strategies produces average lighting energy savings of 38 percent.?

Combining strategies: Many projects require a layering of control strategies in the same space to satisfy different energy code and owner requirements. For example, in an open office, time scheduling may be layered with manual control (for local override of the schedule) and daylight harvesting. Advances in digital communication technology enable multiple strategies to be combined economically, with multiple devices attached to the same control points using a single low-voltage wiring bus.?

Application: Identifying the right lighting control strategies begins with identifying opportunities, energy code demands and owner requirements. What control capabilities does the project need? Manual dimming to support visual needs? Automatic shutoff to comply with code? Daylight harvesting to maximize energy savings? Or a combination of these??

In existing buildings, owner needs and economics drive this choice of control strategies. In new construction, commercial building energy codes are the primary driver, establishing a set of mandatory strategies that must be implemented (see page 70 for some examples).?

Control strategies can be conceptualized and communicated using a written control narrative and control zoning plan. Also called the basis of design, the control narrative describes the lighting control system, including a sequence of operations, or description of system outputs in response to various inputs for each control point. This document provides a roadmap for the control strategies that will be implemented in each space or space type.?

The control zoning plan indicates which lighting loads will be assigned to which control strategies/controllers. This document bridges the conceptual and finished design, providing a visual or text-based description of how each luminaire in the project is controlled.?

By thinking about lighting controls in terms of strategies based on inputs and outputs, specifiers can be strategic about application, which allows them to engage clients in discussion and decision-making based on their needs before even considering hardware. Once control strategies are decided, these hardware choices become relatively simple because they will flow from the choice of strategies.

Do not do business with this company, they do not pay bills. by Paul on 10/13/2017

Empire Electric Equipment Corporation will not pay their legitimate bills owed to vendors. Beware of a bait and switch routine where Empire Electric Equipment Corporation will establish an account, purchase product, and attempt to settle for much less than the original monies owed. Empire owes our company over $21,000 and has been past due for over 8 months. Attorneys have been retained and Empire continues to not fulfill their obligation.

Representatives from Empire Electrical Equipment Corporation continue to promise payment through debt settlement companies, attorneys, accountants, but do not send settlement contracts or payment. Every email to settle debt turns into a delayed response claiming they will pay in a couple of weeks, but never do.

Do NOT do business with this company if you expect to be paid!

Exterior Lighting Designs by Custom Lighting Design on 9/12/2017

5 out of 5 stars
 

This review provides overviews of exterior lighting technologies that would
best be integrated into national parks as retrofits or new designs, as well as tips for
evaluating light sources, performing a lighting audit, and pairing lamps with lighting
controls. The key issues to consider when performing a retrofit or new lighting
design are energy, cost, and maintenance savings, and this guide is intended to
help make these decisions easier.
Lighting in national parks plays a significant role in keeping visitors safe and
enhancing their stays. For example, using the correct sources to light paths and
trails can contribute to visitors’ safety without upsetting the natural beauty of the
park. And illuminating key attractions with energy-efficient luminaires can make
their trips more memorable.
Exterior lighting often is on for extended periods of time, if not 24 hours a day.
By combining high-quality sources with occupant-responsive controls, the
energy use can be reduced with immediate results. In the past, high pressure
sodium lamps were the most efficient choice. However, the quality of light was
sacrificed for efficiency. Improved ballasts for induction lamps, emerging LED
luminaires, and new improvements in HID sources broaden the scope of choices.
When combined with the right sensors to maximize efficiency without compromising
safety, exterior lighting can be vastly improved, typically saving more than
50% in retrofit applications.

Innovative Lighting by sanfranelectricsvc on 9/12/2017

5 out of 5 stars
 

The importance of light is easily taken for
granted. Good lighting can enhance
productivity, heighten safety, and create powerful
aesthetic experiences. Poor lighting can
disrupt lifestyles and even impact health. Yet,
as we develop a more sophisticated understanding
of how lighting influences standards
of living, and new technical and social innovations
emerge, the realms of what is possible
with lighting are rapidly expanding. If the benefits
of this rapid expansion are to be fully realised
then this accumulated knowledge must be
shared. The aim of this publication is to aid
this knowledge sharing and facilitate the transition
towards better lighting in society.
This transition may take many forms. One
example of such a transition tool, discussed at
multiple points within this publication, is the
Product-Service Systems (PSS) model. These
systems provide a radical re-conceptualisation
of standard business models. However, lighting
innovation has applications beyond the market.
Dynamic lighting models are being developed
that allow for intelligent control of learning
environments and ultimately, improved education.
These novel lighting approaches herald a
shift away from “sufficient lighting to undertake
a task” towards “value added by lighting
itself”.
This publication is a deliverable of the Development
to Dissemination (D2D) project,
which aims to enable “developed innovations
to be commercialised across the North Sea
Region”. D2D membership includes representatives
from business, government and academia,
from countries across the North Sea Region.
One partner is the International Institute for
Industrial Environmental Economics (IIIEE).
Another component of the D2D project is the
establishment of the “Samsø Award”. In collaboration
with the Samsø Energy Academy,
Denmark, the Samsø Award aims to “identify,
recognise and empower community-led ideas,
projects and examples that stimulate a transition
towards sustainability”. The collaboration
between students in the Masters programme in
Environmental Sciences, Policy and Management
(MESPOM) and the Academy helped
inspire the writing of this publication.
The following sections include nine case studies,
which discuss models and applications in
public, private and off-grid contexts. Case studies
within the public sector focus on the social
benefits available from novel lighting systems
(Section 1). Innovative business models are
explored within the lighting sector, including
the drivers and barriers to adoption of novel
approaches (Section 2). The report also discusses
lighting within off-grid systems (Section
3). The document concludes with additional
information regarding the MESPOM
programme, the Samsø Award and acknowledgement
of the people who contributed to the
report’s development.
This publication forms part of a series, produced
by MESPOM students, which can be
found in the Library.

Does not pay legitimate bills - Still waiting after 9 MONTHS by jeanette on 9/6/2017

1 out of 5 stars
 

Unfortunately the lowest rating is only 1 star as I would rate them lower were it possible. This company purchased product from us and refused to pay. They tried to settle for less than our cost for the product they sold to a municipality. They make promises but they are empty promises. In our case they paid $3,000 of a $21,000 bill after 9 MONTHS and we are still waiting for the balance.
Will gladly update if and when the bill is paid in full.

Lumens Per Watt by Smith Lighting on 8/7/2017

5 out of 5 stars
 

The energy it took to produce that work In lighting, the work is measured in lumens. The electrical energy is measured in watts.So, to determine the efficiency of a light bulb, you need to know two things. One is the amount of light that the light bulb puts out and the other is the amount of electricity it consumes to produce that much light.


Both of the values you need to determine the efficiency -- the wattage and the lumens, or "initial lumens," should be clearly marked on the packaging that the light bulb comes in. Once you've found those two numbers, all you have to do is divide the number of lumens by the number of watts. That will give you the standard measure of light bulb efficiency, the lumens per watts.

For the greatest energy efficiency and best color rendering, school lighting should employ either fluorescent T-8 or T-5 linear lamp technology with electronic ballasts. The latest T-8 lamps, called second generation, produce more than 10 percent more light per watt than the original T-8 lamps and 50 percent more light per watt than the old T-12 lamps (still the most commonly used lamps in older schools).

•ENERGY COST
Based on an assumption of three hours of use per day at 11 cents per kilowatt-hour. For a 60-watt incandescent, it’s just over $7 per year. CFLs and LEDs both come in at about $1.50 per year.

•BULB LIFE
LEDs dim over time. They’re considered effectively dead when they produce no more than 70 percent of their original brightness. For LEDs, this lifespan is given in hours or years, the latter an estimate based on three hours of daily use.
