thanks selfbuilt
RRT-15 head + RRT-21 body working with 1x18650 Li-ion
beamshot comparison RRT-21, 15, BC40 neutral (last two, 15 and BC40nw)
Nice find! Is there any brightness differences between using RRT-15 head w/RRT15 body and RRT21 body?
I just picked up RRT15 yesterday from the local dealer. Built quality is far more superior than PC25.

Interesting on the hugh weight difference... is the bezel the same diameter on the RRT1 and RRT 15? Here it looks like the 15 has a diameter of 48.7mm - for what ever reason I've seen different sizes listed for the RRT 1 bezel... In fact I was wondering if they actually did change the size at some point?

It better have better build quality than the PC25 -- it costs 56% more.
Jetbeam continues to be my favorite brand of non-custom lights. They seem to be the General Motors (ideal) of flashlights -- a light for every purse and purpose, and none of them (in recent memory) were low-quality relative to their price.

selfbuilt, thanks again for another great review! :thumbsup:
Out of curiosity, have you run the RRT21 or any other broad voltage lights with 2 x IMR18350? If so, are there any issues with the batteries fitting?
Also, is there any advantage to running an IMR18650 in the RRT-21 vs. 'regular' 18650? I understand IMR's are meant for high-drain lights with less runtime as a trade-off but just curious.

Don't have any to try, but if 18650 fit (as they do for the RRT21), you should be ok.
As you observe, not really (unless you like lower capacity and no protection circuits
). Frankly, I don't really see the point of IMR18650 for LED lights - most multi-power lights will not be driven hard enough to benefit from IMR chemistry. The RRT-21 certainly doesn't need IMR18650 - best to stick with protected cells.RGB_LED

Thanks selfbuilt, the main reason I asked about the 18350's is that I recommended the RRT-21 to a friend but he only has an RCR123 charger and going with 18650 would mean he would need to buy a new charger when he is trying to keep his costs down.
Thanks also for your observations and responses about the 18650 - always great to have an expert's opinion!

A really good review.
I just wanted to double check if the RRT-15 can be run on 3 x RCR123 batteries (despite being higher voltage than the CR123 batteries).
This would avoid the need for an extender tube to take 2 x 18650.
(18500 batteries don't appear to be on sale in the UK)

Good question, I don't know. The JetBeam specs don't list an operating voltage for the circuit, and only describe support for 3xCR123A primary batteries.
The difference required for RCR is substantial - you need almost 13V for RCR compared to just over 9V for CR123A (i.e. nominal RCR can exceed 4.2V each). 2x18500 is generally a safe bet in 3xCR123A lights (i.e. 9V is plenty for 2x18500).
Personally, I would be unwilling to try 3xRCR without confirmation from JetBeam (or someone who has run it without issues).
Many thanks for the reply.
I shall go with the 2 x 18650 option (with extender) which will keep the voltage below that of 3 x CR123 primaries.
And now for the outdoor shots. These beamshots were done in the style of my earlier 100-yard round-up review. Please see that thread for a discussion of the topography (i.e. the road dips in the distance, to better show you the corona in the mid-ground).
Sorry, the PA40 should say 4x, not 8x.

Do you know if the Rrt-21 is compatible with jetbeam's pressure pad tailcap?

You got picks at all of the RRT15 with the extender attached?
Did you go the smooth or tactical extender?

Got my RRT15 today along with the smooth extender. Not a bad unit with the extra runtime using 2 x 18650 size rechargeables.
The light looks alot better without the extender but a small price to pay using the rechargeable batteries.

Do you guys think its okay to use the AW18650 3100mah protected cell for the RRT-21? Will that give me the most run time and most brightness out of this light? Will it hurt the light at all?

Should be fine. I haven't specifically tested it, but other flat-top AW cells work fine in the RRT-21. It will definitely give you the best combination of output and runtime.
I have a RRT-15 on the way and would really appreciate any pics you have with the extender on it. If anyone else has extension pics, that would also be great.
