Hi! I have been thinking of getting the jetbeam rrt 0 light for sometime now. I was wondering about the control ring. How reliable are lights with control rings in general? Will they be able to withstand impacts?
The control ring rides on the outside of the battery tube; magnets in the ring are sensed by the control board inside. It doesn't contact any sort of switch, and there's no opening through the battery tube. So mechanically, the ring is actually very simple and sturdy; outside of trying to disassemble it, it's hard to think of a way for it to fail.
Also, does it put out anywhere near the stated 240 lumens?
Just got mine yesterday (Thanks, BugOutGearUSA!), and as soon as it got dark I did some tests vs. my other lights. The closest in form factor is my Quark AA on 14500, which *was* my brighest and best thrower in that size (rated at 206 lumens out the front), but those honors now belong to the RRT-0.
What surprised me is that the RRT-0 also hung in pretty well with my Olight M20 R2, which is rated for 250 lumens OTF; the RRT throws nearly as well, but the M20 has a distinctly brighter spillbeam. Given my brief informal tests out back, and even less formal ceiling bounce tests, I'd say the RRT is cranking out maybe 210 lumens out the front. Not too shabby for a single-cell light.
For EDC lights, I'm finding that flood is generally more useful than throw; I fashioned a cheap, removeable diffuser out of a water bottle cap for my Akoray K-106, and it's become my go-to around-the-house light. While I love the build quality and output and UI of my RRT-0, I really need to come up with a similar diffuser solution for it to become my "do everything" EDC light.
