6. Quiet
The controlLED Lite does not use a ballast and therefore makes no humming or buzzing noises. It’s external
driver is a small electronic module. It is an excellent choice for maintaining quiet environments in libraries and
offices.
7. No Flickering
Conventional fluorescent lamps utilize alternating current to operate. The electrical discharge through the low
pressure gas/mercury mixture has a slightly perceptible flicker equivalent to twice the 60 cycles per second
alternating current. This can cause a strobe effect, where something spinning at just the right speed may
appear stationary. As a result, fluorescent lamps are unsuitable for workshops. Some people even find that
this flickering can cause migraine headaches.
However, controlLED Lites change AC directly into DC and do not flicker. Therefore they protect the eyes and
provide a safe work environment.
8. Does Not Attract Insects
Unlike fluorescent lamps, controlLED Lites do not emit ultraviolet rays which attract mosquitoes and other
insects. controlLED Lites therefore, make a perfect outdoor light source.
9. Better Light Quality
Fluorescent lamps are most often used where light quality (color temperature) is not important, such as
factories, offices and outdoors. When better light quality is needed the fluorescent lamps are often supple-
mented with halogen or incandescent spot lights. LEDs are available in almost any light quality. Therefore
the replacement of fluorescent lamps with controlLED Lites of the desired color temperature can make the
extra halogen and incandescent spot lights unnecessary. Using LED light sources, rather than fluorescent
lamps, also minimizes the harmful effects of ultraviolet light on printed documents (in museums) and cloth-
ing (in retail stores).
10. Operates in a Broad Voltage Range: 109V to 304V
LED lamps will stay bright despite a broad voltage range in the power source. The conventional fluorescent
lamp illuminates its phosphor coating by passing high voltage (with the help of a ballast) through the mer-
cury/gas vapor inside the tube, and will not work without proper voltage present.
11. No ignition Required
Unlike traditional fluorescent lamps, the controlLED Lite does not require the use of a starter or ballast since
it does not need to heat electrodes before starting. controlLED Lites have an immediate turn-on, unlike the
well known flickering start of traditional fluorescent lamps. Dimmable controlLED Lites require our external
LED Driver/Signal Conditioner installed in place of the ballast (which uses the same footprint).
12. Vibration Resistant and Safe
controlLED Lites use a Polycarbonate housing unlike the fragile glass of fluorescent lamps. In handling
and operation, users can feel secure about the safety built into these lamps.
13. Less Waste
Presently over 500 million fluorescent lamps are discarded annually in the U.S.
The controlLED Lite is constructed like other electronic devices; therefore the tube and LED core could be
disassembled and recycled. Since the controlLED Lite has a lifetime at least five (5) times longer than most
fluorescent tubes, they generate 1/5 of the waste in replacement tubes.
14. Environmentally Conscious
Replacing fluorescent lamps with LED lights may qualify for LEED points. Contact your engineer or LEED
consultant for more information.
