Getting a feeler for these. I'm making a couple locally for some fellow EMS workers, and want to gauge interest here.
Price would be $45 shipped, avail possibly end of this month.
Features:
- P60 Dropin
- Solid copper Cu110 slug thermally attached to base
- Reflector is thermally bonded to dropin base
- Electronics and emitter leads are fully potted with thermally conductive compound
- Inner spring is epoxy bonded to driver board
- Powering an XP-G R5 emitter by a 1.4A, Single stage 7135 board
- 6V max input, runs most efficiently with 1x Li-ion (2x123 can be used with an increase in heat)
- .45" wide 8mil copper strip included for maximum heat transfer from dropin to host body.
At 1.4A the R5 should net around ~445 emitter lumens.
MrGman and bigchelis confirmed the R4 variant had 306 OTF lumens & 287 lumens after 3 mins!
R5's should net ~320 OTF.

I currently have a module built utilizing an R4 (~420 lumens @ 1.4A), but future builds will be using an R5 emitter.
Doing some simple runtime tests using a multimeter I came up with the following (May vary with LED Vf & battery):
Tailcap draw on a fresh Trustfire 2400mah 18650 is 1.39A
:05 min - 4.12v - 1.35A
:10 min - 4.07v - 1.36A
:15 min - 4.04v - 1.36A
:25 min - 3.96v - 1.37A
:35 min - 3.89v - 1.37A
:45 min - 3.82v - 1.37A
:55 min - 3.78v - 1.32A
:65 min - 3.75v - 1.26A
:75 min - 3.72v - 1.26A
:85 min - 3.70v - 1.22A
:95 min - 3.64v - 1.20A
At this point I ran out of time, but the light was still running strong. I'd estimate the runtime to be a little under 2hrs with an 18650.
Although the 7135 board runs better with an 18650, 2x123 can be used with an increase in heat. I wouldn't run the dropin with 2x123 for extended amounts of time; in my testing the 123 cells were quite warm after 15min runs. With an 18650, the light gets warm in the hand after a while but not blazing hot. I would not recommend running this in anything less than a full metal bodied flashlight.
Slug size comparison:
Completed module:
Initial tailcap draw:
Beamshots:
Left: Nitecore Extreme Q5, Right: XP-G R4 Dropin, Solarforce L2 host
10ft away from wall:
12" from wall
The dropin is a mix between throw and flood, testing outside I found that the dropin throws a bit further with a brighter hotspot than the Nitecore & lit up a much wider area. You can see in the beamshots how much area it lights up. I'll try to get some outdoor beamshots later.
So, any interest?
