Turning a $10 Flashlight into a BEAST

This host was pretty roached, but it has sentimental value to Paleoellis

Here is a short video of the build: https://www.youtube.com/shorts/0x4qmvxiG4A

The biggest problem with these Zoomies is the “Heat Sink” They are hollow in the middle where you need heat sinking the most.

To solve this I filled it with a 3/4" aluminum rod, by getting the “heat sink” hot enough to expand, and then placing over the top of the cold rod. It made a tight fit.

Drilled/milled holes for wire and set screws.

Cree XPLR has a round die so I think its perfect for an aspherical flashlight

I replaced the missing switch parts, and added a silver plated copper spring

To repair the finish I sprayed it with Duracoat, and baked it. DC is not good for bare aluminum, but it will hold on the harder anodizing pretty well.

I used a mosfet driver so the LED is seeing about 6 amps at peak being driven off one 18650. With the head off, the LED delivers 1800ish lumens.



Paleoellis Sent me this beautiful hand made knife! I really love it, this is the first knapped knife I have ever had.

A real flashlight modding thread?
This must be AI!

A rare sight these days.

Nicely done!
That’s why it’s so important that manufacturers don’t use glue, so that you can swap parts after some time and upgrade the light to keep it modern.

Thanks L4m4. I agree about the glue.. Its especially hard running into potted electronics.

Pretty nice upgrade, thanks for sharing. I really do need to get back into modding lights, posts like this help push me back into the garage and do some tinkering.
