Thanks for your help! I now own and love the GreenForce Tristar LED cannister light. For cave diving it is at least the equal of a 10w HID in all areas--color, brightness, penetration, beam, and ability to signal. Plus it is economical, lightweight, and easy to handle. And the biggies--light head will last forever and is not at all fragile!
OK, I said what we agreed on, do I still have to pay for it?
Only joking, of course. Another great Manta product, and the great service I have come to expect from Manta.
