JETBeam RRT2 Tactical Flashlight Review

JETBeam has out a tactical light with a novel switch.  The light overall is a fairly simple one, but the switch is something new.  It’s a sort of a ‘knock’ switch – lean the tail switch in any direction to change the modes.  Is it good?  Well read on and see!

Just the one version!

Price and Coupon

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.

* Standard measurement disclaimer: I am an amateur flashlight reviewer. I don’t have $10,000 or even $1,000 worth of testing equipment. I test output and such in PVC tubes!! Please consider claims within 10% of what I measure to be perfectly reasonable (accurate, even).

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.  Ie 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 removed easily, but the reflector wasn’t willing to budge.

Size and Comps

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 back side 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 over night, 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 on 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 UI table!

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 moderate throw.  The beam has a tight hotspot, a moderate corona, and a small amount of spill.

Tint vs BLF-348 (Killzone 219b version)

The tint isn’t quite as good as this photo makes it seem, unfortunately.

Random Comparisons and Competitive Options….

JETBeam makes all of the lights catalogued 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.


What I like

  • Acceptable build quality
  • Square cut, well lubed threads

What I don’t like

  • PWM
  • Switch is too easy to deflect – easy to miss modes
  • Tint of emitter isn’t my choice
