Samm Sheperd built this awesome water cooled, 72,000 lumen LED flashlight and took it out for a nighttime stroll.
For a list of all parts used, check out the YouTube description page.
Q: why are you only turning it on for short bursts?
A: The reason is just that I only had one night with the camera guy to get all the shots and I was paranoid of losing battery. The other reason is that it’s so bright that it’s annoying and I loose the ability to see at night
Q:Will it eventually overheat?
A: No, it can run off a power supply continuously with a stable coolant temperature.
Q: How long does the battery last?
A: The small battery back I’m using is made out of batteries I already had, and they will last 6 minutes. A bigger battery is easy
Q: Can I buy one? How much?
A: I am only considering because so many people ask, but it would be like $700 and take a month and a half to order parts and make it and ship it. For serious inquiries sammshep(at)gmail.com
