We've used higher than rated voltage on super
bright led's, although as a strobe not a continuous light. It worked well,
but does shorten the life of LED. It REALLY shortens the life if you dont
have a proper heat sink.

I
know a guy who was experimenting with "pushing" the leds with more voltage for
more light, the mineral oil was used as a heat sink.

You can
buy the individual leds and solder them up into big arrays. Then flood
with mineral oil and use a good acrylic lens.

Do
you want to be able to leave your lights on when your out of the water and
not smell the wonderful small of melting acrylic? Do you want to
save more battery power for your thrusters, and windshield wipers. If so
here is a 6,000 meter depth rated option. That depth should cover
most the subs in are group. ;)'

Oh and by the way, Deepsea Power and
Light 20are sponsers of the Deepsea Voyager Project, so it would be nice
to give them some business.
