Knog PWR Rider 450 Lumen - Teardown

Teardown

Introduction

The lamp stopped working after it fell. I found no other guide to open it so I tried my own way.

The way to open it is from the lens, but I was not able to remove it without damaging it.

The lens broke by trying to remove it because of the latch there is.

I also broke the o-ring because I first thought there was a hidden screw behind the rubber part of the lamp, but there was not.

For now, I don't have a solution to remove the lens safely. But I managed to place it back on with hot glue.

    • I was not able to remove it without breaking it. It has two latches on it's sides. On the picture, the O-ring is also broken while testing another way of opening it.

    • I managed to force open it (and break the latching parts) by using flat head screwdriver and opening picks.

    • Remove the 2 screws (the ones that are NOT near the led)

    • You can now pull from the red side, the whole assembly will come out.

    • The soldering tabs for the battery are very easily broken. In my case it was the part that caused the lamp to not turn on (although charging and programming was fine)

    • Do the steps in reverse order to mount the lamp.

    • If required, use hot-glue to hold the lens

    • Do not put hot-glue in-between the lens and the LED

спасиб тебе, чувак, нигде нет инфы как этот фонарь разобрать, получается там стоит обычный 18650, что-то спустя 4 года начал быстро разряжаться

Like yours, my pwr too stopped working after it fell. Charging was working fine, but the light wouldn't come on. The battery in mine is shorter and wider than the one in your photo. I reinserted the battery, it didn't work. i guess it's time for the garbage. I never thought I would find guidance on disassembling this light on the internet, but I just want to say thank you for providing such valuable instructions. Your detailed steps and excellent pictures were incredibly helpful.
