Need help with LED lighting.
I see tons of LEDs and diodes and new flip chip technology. It's all very confusing. I'm basically trying to make the brightest light in the smallest application. It will be mounted on a pair of glasses with a set of loupes on them. I don't want the diameter to be any more than 1 inch.
I found a website that can cut a lens to any dimension I desire. I basically want a spot beam that will be about 5 inches in diameter from about 18 inches in distance. It will have to run off some sort of battery pack.
I was thinking of just taking a LED bulb element from a flashlight and slapping a lens in front of it to focus the light. Really not sure what type of LED bulb to buy or if it might be better to build my own. I see companies advertising their LED dental loupe light at 8,000 lumens which seems fairly impossible since most diodes seem to only be rated at 100 or 200 lumens at the most.
Any advice or guidance would be greatly appreciated.
Thanks in advance....
