Water Cooled 72,000 Lumen LED Flashlight!!

People wanting a big light for their car: light bars exist now, cheaply and reliably Here's that neat 1150 lumen light: FAQ's!!! 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 LED Chips: LENSES: Resistors I recommend using Boost converters to drive the LED's from 12v or so (No resistors, one per chip, can also drive the cooling stuff with the same 12v): Cooling Blocks
