That’s a big flashlight

Going camping? You’ll need an extra backpack to carry this flashlight along the way. On the business end you’ll find 500 five millimeter super-bright white LEDs, on the opposite end there’s ten times the number of controls you’d expect on a flashlight. At full power, the LED array pulls down 50 Watts, making us question the battery life of the unit. Check out the walk-through after the break. The LEDs are mounted on proto-board, making for some extreme point-to-point soldering. During the control demonstration there’s a background noise like a jet powering up, what’s that all about?

While this terrific torch brings a grin to our faces, we wonder if it wouldn’t do better as a vehicle mounted illuminator. Or if a microcontroller was tossed into the mix some creative code could make this a pretty powerful yet non-lethal weapon.

  1. This 500 LED creation is totally amazing! Around the year 2000 I wanted a bright LED flashlight, all I could find was wimpy little single 5mm LED flashlights. So I started building my own multiple 5mm LED flashlights, etching my own circuit boards, mounting and soldering the LEDs. I made tons of them and sold them to friends and relatives. I used up to 20 5mm LEDs. I’m totally dumbfounded that someone has the wherewithal to build a flashlight with 500 5mm LEDS!!!

    I ended up starting my own company ( http://www.elektrolumens.com ) building high power LED flashlights (Lumileds, Seoul Semiconductor LEDs, Cree LEDs, etc.). I presently build possibly the biggest and brightest multiple high power LED flashlights in the world (up to twelve Cree MCE LEDs), but, I have to say, this creation is quite amazing. I’d love to own one, but I could never ever sit there and solder 500 LEDs into a board, no patience for that.

    Give this man credit for his accomplishment. His flashlight should go in the Smithsonian Institute!

    Saw this as a featured video on youtube so I had to pass it along to hackaday. Brought a smile to my face seeing 51 comments!

    I bought this flashlight:
    Features of Streamlight TL-2 Xenon Tactical Flashlight:
    • 6 volt xenon bi-pin bulb with 30 hour life (approximate)
    • up to 7,900 peak beam cp, 114 lumens

    It’s powered by two 3v 2014 batteries. Imagine using 5 of those xenon bulbs? This flashlight is bright enough to make you look away, even outdoors in full daylight.

    wouldn’t you call batman with this?

    At 50W, can you fry an egg on it?

    Otherwise fantastic – should streamline the build process and sell them at baseball games as novelty spotlights.
