GE ConstantColor™ -
bright throughout life
GE ConstantColor™ halogen lamps have a unique glass reflector
coating that provides consistent colour performance throughout
their rated life. It is GE’s Thin Film Technology that makes this
possible. Conventional halogen products utilise a reflector coating
that is gradually degraded by the heat emitted by the filament,
so the quality of light changes. Unlike any other product on the
market, GE’s ConstantColor™ lamps withstand temperatures of
500°C without a change in reflector qualities. The result is close
to 90% maintained light output over life and identical colour
temperature from lamp to lamp.
With coating applied to both inside and outside the reflector,
wasted backlight is virtually eliminated. The small amount of
light that does escape through the reflector is a consistent hue
which will not vary from lamp to lamp through life, ensuring
replacements do not appear different from existing lamps.
Excess heat is handled the opposite way: the coating allows 66%
of the infrared light (i.e. heat) to pass through the back of the
reflector, so that it is not projected onto displays.
Halogen-IR
Standard incandescent and halogen lamps lose
approximately 76% of the input energy by radiating
heat, and convert only 8% into useful light. The Precise™
IR halogen capsule has multiple layers of very durable,
thin, interference film which redirects heat, which would
otherwise be wasted, back onto the lamp filament. This
increases the filament temperature and allows it to give off
more visible light for the same input power.
The increased burning efficiency provides the same light
performance with a significantly reduced power input,
alternatively allows a longer lamp operating life or a
combination of both.
