First off, I just want to say this is the best forum ever. I don’t do much to contribute at all since I feel as though I am subpar compared to the great gurus here. In any case, since I so avidly real the forum, I have been fortunate enough to receive some stuff at the generosity of out members.
For this mod, I got the XP-C module from a 2-AA LED mini mag from Old Lumens.
I then got an 18500 LiFePO4 cell from mattthemuppet.
So, thanks guys for your kindness, and here’s what I did with the parts.
Everything before I started.
The host was a cheapie 9-LED direct drive from 3-AAA light. The module modes are high, low (with nasty PWM), a slow blink (which might be nice for a bike), and SOS.
I got the cell since I thought it would be a good replacement for the holder. The dimensions are close. The 18500 is just a bit skinnier.
The 3.2 V powered the stock light up as is, but it still is as weak and as blue as ever. Since the mag module is designed for 2-AA, I thought LiFePO4 would be a perfect substitute.
Here’s the head after I swapped out the LED board. I had to flip the “reflector” over so that there was enough space for the whole module. It had enough depth to it so that the “lens” could go back on and not touch the led dome. Everything was just press fit. A bit of copper wire squeezed between “reflector” and tube wall on one end and squeezed between retaining ring and module side.
Here’s a shot into the tube. I added some TP roll to keep the battery from wiggling too much. I also bent the tab a bit on the module to make sure it contacted the positive terminal well.
It works!
It’s a pure flood mule.
Thanks again O-L, MtM, and BLF!
