How to make a very bright flashlight


Sometimes I need a brighter flashlight and I can’t find a placae to buy it because all of them are not so bright. Or if I find one it is very expensive.

With a few dollars you can build one of the brightest led flashlights in the world, something like 900 lumen output.

This is interesting because you can play some games on your friends with that flashlight because it is sooooo bright. I wonder how much energy does it consume.

    Well, if you search for “ssc p7 bin” in google, you do get websites that sell an LED emitter rated at 900 lumens. I guess its just a question of cutting the small LED out of the flashlight and putting the bigger one in. People who are good at hady work can probably figure it out from there, otherwise…

    Yes, this video is missing the how to part. But, remove old led and solder new led in its place? With thermal grease to help transfer heat to pcb? Do both leds draw the same current at the same voltage? LOL, well generally the driver circuit will adj the drive voltage across the led to drive rated current through the led. I wonder how hot the flashlight gets in operation?
