I am not really sure when you would need a hand-held 90,000 Lumens flash light.  The kind of light that lights an entire mountain side from far, far away. It is actually so bright, that I find it hard to think about applications for such light. (100W seems to be enough, no?). But it can be made, so youtuber rctestflight made it, and explained how to build one yourself.

The light is made from 10 individual smaller lights, each made from the following pieces and gives about 9,000 Lumens. The mind blowing total is about 90,000 Lumens.

So each “light bulb” is about  $25. Add to that an aluminum bracket, some thermal paste and two 12V LiPO batteries. And you have just made a crazy bright flash light for $300. What will you do with it? I have no idea, it will blind anyone looking at its general direction :), but rctestflight has some ideas:

    Apparently the cheap 100w LEDs seldom function as they are promised. https://www.youtube.com/watch?v=NjKgPLeJ79Q

    That’s not a light, it’s a collapsed sun.

    That’s “heatsink” not “heat sync” just for future reference.

      Hey Desmond! Funny seeing you here – I saw this article and was going to send you the link via the NZ Photography page – you got there first. I thought this sort of mad scientist project would be up your alley…

    Cool. Nothing like being able to light up an entire stadium every time u take a photo

    Looks like it would be perfect to shoot at night; set it up behind a big scrim and you could totally light a big scene.

    Great friend project, I want to ride something like that your project. A doubt about the batteries … They are connected in series or parallel?

    What Heat Sink to get?

    Any way you can put 4 of them together?

    those batteries dont look like they have enough current available to produce 1000 watts for more than a couple minutes, if they even can at all, I build massive Flash Lights” all the time and the battery pack I use for the 300 watt is a lot more than what I see them using, plus the fact Ill wager the 1000 watts is more like 600 at best ( better guess would be 500 or less) and again only for a short duration of time. My lattest is a 400 watt (True output) with a 3 watt UV laser coming from the center LOL

        I would be happy to help although putting an email address online would surely get me LOTS of email :)

      Watts is a measure of power consumption. Not light output. :)

    The link for the LED driver is dead, can you give us the make/model? Cheers

      go to ebay and search 150w boost converter they claim 94% efficient but most I get is around 85%.
      in other words they draw more current than you actually are using for the device, for a 3200mA draw to power a LED the total draw will be around 480mA more

    I made a new style lighting system, first for the paranormal people but it works well for photographers as well, it seems to reveal things that dont show up under normal lighting or IR lighting, once put together in a attractive housing I will put up for others to see and try
