Brian,

Try Luxeon Star LED's....they're pretty bright and I believe are available
in 5 watt versions.  You can get them on Ebay or directly from the
manufacturer...Luxeon.

Hi Andy,

Speaking of LEDs, I would like to make a really strong dive light using
LED's ,  I'd like to push them a bit to increase their intensity.  I was
thinking of using a clear vinyl membrain (like the kind Phil had) and
mineral oil as a heat sink and as a pressure equalizer.  Do you know a good
source for some birght LEDs?

Brian

Have you guys ever heard of LED throwies:
http://www.instructables.com/id/LED-Throwies/

The idea is a small battery, magnet, and LED.  I think it would not be
too hard to make it a bit more water proof.  You could low level cheap
independent illumination wherever you needed it.  You could add a button
and or a switch so you don't go throw too many batteries.

Nice thing about a steel hull..you can stick magnets anywhere..
