Cree MC-E P60 drop-in Mod

Cree MC-E LED P60 Drop-in

I was a little disappointed with my DealExtreme Cree MC-E P60 drop-in (SKU 21037). The specs say that on high, it should be pulling 2800ma and putting out 410 lumens. I measured 1.67A on high with a Li-Ion 18650 battery. But for $23.49 USD, I couldn’t complain too much.

I saw that Shiningbeam.com has a 3-Mode Regulated Circuit Board for Cree MC-E and SSC P7 LEDs (SKU 1217). Their specs say the output current is 2500mA on high. I thought I’d try it as a replacement for the circuit board in my DX drop-in.

It was an easy replacement since the Shiningbeam circuit board diameter is the same 17mm as the DX drop-in board. I am using it in a bored Surefire 6P body with the Surefire 6P bezel and a Solarforce L2-S4 tailcap.

The drop-in was a little loose. I had been using a Malkoff Beryllium-Copper spring washer, but it didn’t work too well this board. I cut one turn of a P60 drop-in spring and it creates a 1mm gap between the bezel and the body, but it works. I also had to put a longer spring on the circuit board because without it, the battery was loose.

After I wired it up, I measured 2.39A on full power with the same battery, so it’s a worthwhile replacement. I don’t have the means to measure the light output except for the current draw but it is much brighter than the stock DX MC-E drop-in – though it still doesn’t look as bright as my direct drive P7 in my Ultrafire C2.

The other nice thing is the Shiningbeam board has Low-Medium-High modes as opposed to the High-Low-Strobe on the stock DX.
