I have tinkered with high brightness LEDs for some time. My conclusion
was LEDs significantly outperform other sources only in situations
where you need single color, such as nav lights, red cockpit lights,
traffic lights etc... For white light applications their performance
is less impressive. That is reasonable because LEDs inherently produce
single color photons, while incandescent sources produce a broadband
of photons. You lose efficiency converting a broad band to a single
color, and you also lose efficiency converting a single color to a
broad band.


This is not true anymore... the LEDs we are using are now available in
efficiencies as high as 100lumens/Watt. That is better than a compact
fluorescent light bulb. You can not look directly at the LEDs we are
using when they are on. If you do, you will see spots for quite a
while afterwards.

Also, it is not fair to just compare the brightness. You should also
consider the weight of the heat sink and extra circuitry. In addition,
LED lamps are typically thermally bonded to their heat sinks so
individually replacing burnt out LED may be difficult or impossible.
You might have to replace the whole array. They are insensitive to
vibration, but are more sensitive to temperature fluctuations.- Hide quoted text -


Equivalent halogen wing-mounted landing lights are no lighter than our
product, and we are much brighter. Duckworks touts their light-weight
halogen light as being only 15.5 Oz (0.97 lbs) which is about the same
weight as our unit...
