I recall a light at an antique shop bolted to a battery bigger than that one in the photo. I know it was bigger because I have a light like the one in the photo. That is a Ford Model T head light in the chrome dish by the way. The one I remember was a lead acid battery with a light bolted to it. Anything should be lighter than that.
Anyway, last time I was upgrading lights the T6 bulb was the latest thing. I know about the need for constant current drivers. I was thinking if I wanted to make a modern light with a similar form factor, it might have 4-6 Ah 20V drill batteries arranged vertically in parallel. I would need a BMS board that would have a low voltage cuttoff for the batteries, likely one for each cell since I don't code. I could use the power wheel break out adapters to connect the batteries which are about $10-15 each, though we will leave that out of the total. Lets assume I have the batteries already, and I want spot to flood capability. In the summer the night temps are as high as 80F, and my walking commute was 1hr, so I'd want at least 1.5hrs sustained brightness. Hypothetically, I have about $100 for the reflector, bulb, and driver, and have plate steel, and a small pile of Pentium 3 heat sinks that could be in the front or back, as long as they do not interfere with the handle, plus a drawer of 80mm PC fans. What type of diode would I be buying, and what kind of output could I expect to maintain?
