Re: [PSUBS-MAILIST] LED Lighting Options

Frank I am also trying to use these hand held million candle power lights.

I am just using the reflector and bulb. Putting them in a steel fire extinquisher hsg.

These vessels you can get for free usually from a supplier and I am pretty sure they

will take my modest depths. For sure the heat will be an issue. only turn em on

under water.

They will be powered by some of my external lead acid batteries and will use at

least 3 of em. I have know idea how dark it will be in Lake Superior or the visibility

Love the unknown hehhe

I've used regular scuba dive lights and they don't put out much light. I can see where an LED set-up would give diffused light without much distance capability. I wonder how a high power focused light shone from behind a viewport would work. I have a hand held spot light that's 12 volt and has 1 million candle power. It gets a little hot close to the lens but at 6 inches is only just warm. It can be focused into a tight beam and will run for several hours on it's batteries. It takes a lot of Duracells to load it up though. I plan on using it as a back-up inside the sub so will report on it when I take the sub out. Frank D.
