Hi all, I’m accepting offers for my custom 2.5MCD 14500 Lumen superthrower, I’ve calculated the throw based on the intensity and got 3.1Km. This light is powered by a custom 3S 21700 battery pack with a built in BMS. It uses an internal CC boost converter to drive the LED. This is a monstrous thrower that draws around 150 watts and has a built in fan with heatsink (which can get quite loud). This is a one-of-a-kind thrower I’ve been building for a little over a year now and It’s finally finished. I’m forced to let it go because I live in a place where I don’t have much space to use it and actually be able to appreciate it’s throw. I’m hoping I can sell it off to someone that’ll be able to enjoy it a lot more.
Here are some beamshots:





Here are some photos of the light itself:





The material cost of this thrower was around $200 and took me over a year to fully realize, there were quite a few failed attempts and scrapped materials involved in making this thrower. I am accepting fair offers, please PM me if interested. Shipping out from Michigan, US.

You might get a better chance of a good buyer if you gives a little detail of where it would be shipped from. At least the Continent, it is a world wide board after all.

Shipping is generally expensive these days.

What led does it have?
What’s the diameter of the lens?
Is the housing 3d printed?

it uses the osram LE CG P2AQ, which is a high power projection LED never used in a flashlight before. the lens is 150mm and the housing is all custom 3d printed parts.

I have another scrapped project very similar to this that used the LE CG P1AR, which is a very similar LED but less power and emission surface area. I scrapped it because the throw wasn’t as good as this one.
The LE CG series LEDs are fantastic for this sort of application and they’ve never been used in flashlight before probably because of their form factor and power requirements. It makes it kinda hard to implement but with the help of some 3D printing, I was able to get it to work. Osram released these in August of this year so they’re relatively new. I stumbled upon them while doing a parametric search on mouser a few months ago.
