So I have this light… and I know it’s been out a while… but Massdrop had it for $30 a while back. I bought it, and did some testing on it, and I’m getting 548 lumens out the front. Most old reviews from way back when, and Jetbeam’s figures state a maximum output of 450. I know similar models like the RRT0, produce over 550 OTF. So is it possible that Jetbeam has updated the driver in it’s RRT21? Did anyone else recently get in on this deal, and can confirm? My multimeter got about 1.3A at the tailcap. It may be more, but I don’t have great leads, just the stock ones. Also it just has the old XML led in it.
One more try? Anyone?
Don't know, but if it still has an XML, then I would expect it to have been untouched.
All I can say; that thing looks reAlly good! Love the quality and feel of it.
Okay, I don’t know what’s going on then. Thanks for the response though!
