Saw these on sale the other day and bought one.

Has an SST50 led, uses one 26650 battery.

I know there are lots of overdriven xml's and lots of other stuff out there. I'd always been pretty happy with xpg's, then xml's. And I know you can find more lumens for cheaper.
It only puts out 1000 to 1150lm or so, I still really like it though. Can't wait to use it underground for the first time. At night in comparison, it makes my L2P/xml look really dim.

lumens? run time?

I will quote myself from the initial post,

As well I'll put a quote from the LINK that I provided for information,

3 Modes: High (100%) / Mid (60%) / Low (30%) Input Runtime: 2 hours with High mode output

The summary is, similar efficiency to the XP-G, much higher current rating though.

The summary is, similar efficiency to the XP-G, much higher current rating though.

if it's "similar" to the xp-g but with a higher current rating, then it's not really "similar" is it?

I mean, you hear about people hot-amping the xml's all the time, but not so much the xpg's. If you can give an SST50 more current and get a higher output level, but you can't give that much current to an xpg, and can't get the same output, then how's it similar?

Or do you just mean, up to the point that you CAN give an xpg the same amount of current?


Still need to create a custom cradle for my 26650's. Been using alligator clips & rubber bands to charge them. Was using some small magnets at one point but they didn't have as low a resistance as I would have liked. (and, I lost them) =)

The XP-G doesn't overdrive as well as the XM-L. That's partly due to thermal considerations. The SST50 and SST90 have lower efficiency than Cree's best, but they can be run at much higher currents. If you take an XM-L up to about 4 amps, no practical design lets you see any benefit from much more current. The light output will not increase much on a lab bench, and the heat in a flashlight will cut XM-L output dramatically in use over about 4 amps.

The SST50 and SST90 are rated and see benefit to about 5 and 9 amps each. So IF your driver can kick amps that hard, then you can get really monster output in a given-size light. The single-LED offerings from Cree top out at about 1000 LED lumen in a good installation. The SST90 can get up to 2200... At about 3x the current. But that's almost doubled output and throw, so it has its draw.

OF course, these are big LEDs which need big optics.
