Official Specs and Features
Here’s a link to the JETBeam RRT2 Tactical flashlight product page.
Versions
Just the one version!
Price
This light is surprisingly inexpensive, going for $27.19 at GearBest at the time of this writing.
Short Review
This is a very simple light. With the dual springs, it’s probably ok for gun use, but the switch is much too sensitive for me.

^ Measurement disclaimer: Testing flashlights is my hobby. I use hobbyist-level equipment for testing, including some I made myself. Try not to get buried in the details of manufacturer specifications versus measurements recorded here; A certain amount of difference (say, 10 or 15%) is perfectly reasonable.
What’s Included
- JETBeam RRT2 Tactical Flashlight
- Nylon pouch
- Lanyard
- Tactical ring
- Spare o-ring
- Manual and papers
Package and Manual
Standard JETBeam blue and red package.
The package is a box within a box/sleeve. The light is held in place by two small foam pieces.
Build Quality and Disassembly
I’m satisfied with the build quality for just a general-purpose light. As for actual tactical usage and gun mounting, I’m less sure.
The head lacks many cooling features, but the light is not driven hard at all anyway. i.e., cooling is never a real issue.
The threads are pleasantly square-cut and lubed well, and anodized. Mechanical lockout is easy with a short twist.
Both the head and tail have springs, and they’re quite beefy and long springs.
The bezel was removed easily, but the reflector wasn’t willing to budge.
Size and Comps
Officially:
Length: 143mm
Head Size: 33.5m
Weight: 134.3g (Excluding Battery)
It’s a long light, no doubt.
Retention and Carry
The included nylon pouch is pretty standard, with stretchy sides. The light will fit in either direction, too.
The pocket clip is the collar type and is a nice quality clip. It can be removed easily (slide it over the o-ring carefully). The backside of the pocket clip has a lanyard hole.
With the clip off, the tactical ring may be used. It has a lanyard hole, too.
Both the pocket clip and tac ring can be removed, and the light functions perfectly without them.
Power and Runtime
The RRT2 can be powered by an 18650 or 2xCR123 cells. I tested only with an 18650. My package didn’t include a cell, but I think it’s possible that some might (it’s pictured with a JETBeam cell on the product page). On the high end, the output is the same between the two. On the low end, the 2x cells output a little more.
Below is a runtime on the highest mode. After a little temperature-controlled 20 minutes or so, the output tracks the cell voltage all the way down. The light did not shut off.
Here’s a runtime on Medium. The output is fairly stable but quite low. Also, no LVP in this case. In fact, this test ran overnight, and the light was still on when I got up. That said, the output was so low that the cell never got below 2.75V anyway.
Unfortunately, the light does not seem to have LVP. Also, unfortunately, there’s PWM in every mode. Every mode. It’s particularly bad (not just “noticeable”) on the low mode.
User Interface and Operation
There’s just one switch on this light. It’s clicky like a mechanical switch, but definitely has some e-switch components.
Here’s a user interface table!
| State | Action | Result |
|---|---|---|
| Off | Click | On (Mode Memory) |
| On | Click | Off |
| On | Deflect Button | Mode advance (HML) |
| Any | Hold Button Deflected | Momentary Strobe (Release to previously used mode) |
| Off | Half Press | Momentary Memorized Mode |
Modes and Currents
| Mode | Mode Claimed Output (lm) | Claimed Runtime | Measured Lumens | Tailcap Amps |
|---|---|---|---|---|
| High | 950 | 1.5h | 805 | 1.95 |
| Medium | 180 | 6.5h | 181 | 0.35 |
| Low | 0.6 | 100h | – | – |
LED and Beam
The RRT2 has a Luminus SST40 N4 BC emitter. The reflector is smooth and deepish and is good for a moderate throw. The beam has a tight hotspot, a moderate corona, and a small amount of spill.
Tint vs BLF-348 (KillzoneFlashlights.com 219b version) (affiliate link)
The tint isn’t quite as good as this photo makes it seem, unfortunately.
Random Comparisons and Competitive Options
Here’s a link to parametrek.com, already filtered for you. JETBeam makes all of the lights cataloged by u/parametrek for this emitter. If that’s your sole classification, then this is probably a good tactical light for you. There are many other lights I’d pick first; I do not care for this switch. It’s neat but too easy to overpress.
Conclusion
What I like
- Acceptable build quality
- square-cut, well-lubed threads
What I don’t like
- PWM
- The switch is too easy to deflect – easy to miss modes
- Tint of the emitter isn’t my choice
