M@g 1.5C neutral white XP-G

[Hill]

Here is the newest M@g custom to join the ranks. This build was designed to drive the XP-G @ 1.4A using the M@g rebel “deep” reflector. It’s overall output is significantly lower than several previous builds, but what it lacks in total ouput it more than makes up for it in throw. In fact, compared next to by quad XP-G, it has the “appearance” of being brighter due to the pencil like beam.

Thanks to ma_sha for his tutorial on m@g cutdowns from the tail which preserves the head focusing function. The size (1.5C) is a perfect fit in my hand and accepts all sizes of "larger" li-ion cells (26650, 26500, 18650). All maching done by hand with basic tools (hacksaw, dremel, file) pictured below.

Thanks to those that came up with the M@g C switch bounce fix (especially Aircraft800) that help solve that annoying level jumping with the multimode drivers.

Estimated ouput driven @ 1.4A is ~450 lumens compared by ceiling bounce next to my other lights.

The process in reverse order of build




XP-G on lowest setting


White wall shot @ ~ 1 meter. Nice neutral tint.

Size comparisons (left to right) M@g 1C, 1.5C, 2C (stock)


How it looks in the hand (same order as above)




Head removed. The heatsink diameter was a bit to small so the gap was filled with aluminum strips cut from a soda can


Completed light engine mounted to switch


The very short wires meant partially disassembly of the switch to solder the (+) contact to the driver


View of driver mounted to heatsink


Assembly of heatsink, driver, and spacers


Cutdown switch


Heatsink (underside) showing driver slot


Heatsink (emitter side)


Machining of tail end to join the cut sections. This was the most difficult, but came out pretty good. I will JB weld the ends to keep them permanently connected.


Cutdown of stock m@g 2C. The 3rd section from the right was removed

Thanks for looking. Comments always welcome !

Looks good, just shows what can be achieved with minimal tooling, well done.

haha, Glad to see some more DIY cut-em-down going on around here,
looks pretty good

You're a great teacher

We all need to chip in and get Hill a lathe

I'm all for that...then it'll be free unlimited machining to all . Of course, Will Quiles, Mac, Mirage Man, Jesus Hernandez, Led Zep, and the like won't be very happy with that
