7W Golston® 2xCR123A Waterproof Super Bright
I think I am the very first ones to get one of this 7 Watt light and modded it take a 18560 rechargeable Li-ion cell with the reisitor removed.

Anybody tried Dae's $10 5.5W Luxeon?
One more interesting thing about the LED, the emitter is part of the heat sink (star). It appears that on top of the aluminum heat sink, they have put a layer of insulation, then copper, them the LED is directly deposited on the copper printed circuit. Therefor you cannot de-solder the emitter...- dcarch8

a flat 5w Luxeon flashlight
Absolutely. Agree. I know the danger of li-ion batteries first hand. As I said, this is only a proto type for me to figure out a few things before I get to make the final thing, to solicite a few suggestions from the experts here on the design, etc. Thanks for the observation. dcarch8- dcarch8

Suggestions on how to power a couple of CCFL tubes with batts?
They have inverters (5V) which will drive two 10" tubes. You may need to have two tubes going if you are using it as a work light. 12V is a pain for batteries. Unless you have spare laptop batteries, which are 10v to 14v and over 2500 mah. dcarch8- dcarch8

Anybody tried Dae's $10 5.5W Luxeon?
As I said, the LED is very strange, so I inspected it with a high power magnifying glass. First, there is no plastic encasing the anode/cathode. Could it be that mine is a manufacturer's reject? I would be interested in knowing if others are the same as mine.:thinking: Normally there are...- dcarch8
