It may be much better to light a single candle than to curse the darkness, however that was before [RCTestflight] came up with this: a 1000W LED flashlight that outputs about 90,000 lumens of light. That’s a lot: the very best pocket LED flashlights output about 700 lumens.
[RCTestflight] developed this monstrosity utilizing ten 100-Watt LEDs, running off two RC cars and truck batteries. Each of the LEDs is linked to a large voltage converter as well as a extremely big heatsink that holds all of them in place. He states he gets about 8 minutes of light out of this thing, as well as that the heatsink gets warm after a minute or two of use. We’re not surprised: LEDs are a lot more effective than a lot of other gadgets at converting electrical energy to light, however some always gets lost as heat.

If you truly want to light something up it does a excellent task (for a short period of time) due in part to the inclusion of a glass lens for every of the LEDs. This successfully focuses the beam on a appropriately distributed area. We question what would occur if all the beams were focused on one point? As long as you don’t cross the streams…
We have covered a few a lot more functional develops utilizing similar LEDs, however this thing does have a specific outrageous charm, as well as might be beneficial for high-speed video, where the a lot more light, the better.
