Well, I think that I “did a bdiddle”, or maybe “worse than a biddle” (or “better”, depending on your viewpoint :laughing:….
I stacked 2 R200s on top of the 2 R180s, and I measured tailcap on high, and got……
~8.79 amps!!!
that only lasted a few seconds though, until the light died :(…
I inspected the driver, and nothing looked like it burned or popped, so I took the whole head/pill apart.
Then, I tested the emitter (the original XM-L on the big 20+mm star) and, that was dead.
So then, I wanted to check if the driver was still working, but I didn’t want to pop another emitter, so I removed the 2 R200s, and hooked up a new (old) XM-L on a Noctigon, and fired it up connected to my bench supply, and got LIGHT!! And modes even :)!!
So, I added 1 R200 back on top (so I was at 2 x R180 + 1 x R200, or about equivalent to R069), and put it back into the light, and tested tailcap and got ~2.21 amps, or about 17.68 watts (into the driver). That would be about 5.89 amps (17.68/3) to the emitter at 100% efficiency or ~4.71 amps to the emitter at 80% efficiency.
Seems like that’s probably a safe place to be for this light?
Now, going tangentially: I’m wondering how this light would do with an XP-G2 instead of an XM-L? Would this be a good thrower? It seems like the head/reflector, while not huge diameter, isn’t bad, but would an XP-G2 do ok at ~4.71 amps?
Also, would it work with this reflector? Or maybe I’d need to use something like this:
