LED Performance

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.
