I got a nice Black Friday deal on a JETBeam RRT-0 flashlight from the people at LightJunction.com. I read bondr006’s great review on Candlepowerforums and it looked like a really nice little light. The main feature of the JETBeam RRT series is the ability to adjust the brightness to different levels by turning the Rapid Response Control Ring at the base of the head.
The RRT-0 is also versatile because it can use 3.0V CR123 primary batteries, 16340 3.7V rechargeable Lithium batteries, 1.5V AA primary batteries, 1.2V AA rechargeable batteries and 14500 rechargeable Lithium batteries. The latter three require the AA extender, which adds a little more than a .6 inch (16 mm) to the 3.8 inches (97 mm) length.
I have a JETBeam Jet-I Pro I.B.S. flashlight, which is slightly smaller in size. The RRT-0 is a little larger in diameter because it can take CR123 batteries and a little longer, because of the rotary switch built into the body. I can also set a “lower” low level output on my Jet-I Pro. The RRT-0 also lacks a strobe mode – which I would probably only use if I was lost in the mountains at night needing air rescue. But I could always use the forward clicky switch for signaling.
JETBeam claims an output of 240 lumens. I have not seen independent confirmation of these numbers, but my RRT-0 (with the SMO reflector) certainly looks close to my Malkoff M60 drop-in. In laymen terms, Surefire describes 200 lumens as ten times the light of a big two-D-cell flashlight. For a flashlight this size, the JETBeam RRT-0 puts out a lot of light.
