Let the battle of the kings continue..
I put on some XP-G2 R5 3Cs on copper. XM-L centering rings were connected with fujick. I put some kapton tape on the back of the reflector (short circuit saftey). Solder connections were low.
The MCPCBs were a bit loose so I only checked emitter current for 5 sec. Results:
3,55A... (!!??) What, that high, on XP-G2?? That looks promising. Did not expect that.. :)
2,61A.. what, that low, that was lower than anticipated..
2,71A.. Low on that on too..
That is 8,87amps total, or an average of 2,95. NCR18650B @ 4,05V+ were used. They were not freshly charged and slightly used. I double checked the 3,55A and got the same number twice. Dont ask me...
Supfire M6 XP-G2 R5 3C on copper @ 2,95 average vs SRK XM-L2 T4 5B1 @ 3,09 on copper
Sure it out-throw the XM-L, but not by much. The XM-L light "throws" a much more wider beam, and it puts out a lot more light. To me, the XP-G2s were more of a let down in real life than in the pictures.
Supfire M6 XP-G2 R5 3C on copper @ 2,95 average vs SRK XM-L CW-dedomed @ 2,3A on copper
The de-domed XM-L at lower current (2,3A) kills the XP-G2 light at 3A. No contest...
For this particular test, I had rings and one ugly ring in the XP-G2 beam. So question is, would there be a significant improvement if the reflector sat lower?
After I took the beamshots I removed the XM-L centering rings, did another attempt at getting the soldered wires even lower. That should make the reflector sit marginally lower. Result was pretty much the same. I know I could make the reflector sit lower by using some pieces of brass plate on the MCPCBs instead of wires, or just modify the underside of the reflector. Instead of messing around with the M6 reflector I changed to SRK reflector since that was easier.
Why?
M6 reflector on the left, SRK on the right. As you can see, the place where the wires on a 16mm mcpcb sits crashed with the flat surface on the M6 reflector . Changing the stock MCPCB with 16 mm stars is no issue when using XM-Ls. But XP-Gs need to sit further inside the reflector. That is easier to achieve with the SRK reflector..
BTW, kapton tape is not a good insulator as it can easily be broken, I just sometimes use it instead of a proper insulation pad/plastic thingy when height is an issue.
Supfire M6 with SRK reflector. The reflector sits directly on the XP-G2s mcpcb now. Focus is much better and no ugly ring..
Temporary I planned on putting the M6 reflector on the SRK, but due to the MCPCBs sitting further outwards in that reflector I would have to cut about 1 mm of the MCPCBs when used in a SRK in order to get them further out to the edge.
To be continued..
PS: Warning once you think you have cycled through all the modes, you point your eyes towards the reflector in order to check something.. "poff, and there goes you vision. D%¤# SOS!
