For anyone who wants to run an 18650 with your original RRT-01: a Crelant 7G3CS battery tube fits nicely onto the original RRT-01’s head. Gives the RRT-01 more runtime with a lockout clicky. Overall length is roughly 120mm, IIRC . Anodize color will be off, but I use my lights for more than photo-ops.
Cheaper and much less time consuming than taking to the lathe and CNC.
The light lends itself to much improvistion. The screw in lanyard makes adding machined or 3D printed attachments easy as well. On a 3D printer, I made a twist off RRT01 lanyard cap for father-in -law that holds pills and hearing aid batteries
Incidentally, the threads in the old RRT-01 are compatible with the threads in the Manker E14 / Astrolux S41.
This means you can take an 18650 tube from those lights and lego it onto your old version RRT-01 head to get instant 18650 support.
There also tailcaps available for that thread pitch without without switches on them. So if you want a flat back with no switch it’s possible to do. I just tried it with parts on hand and it worked.
While the threads on those lights are the same as the threads on the RRT-01 head, it should be noted that there are more threads on the Astrolux/Manker tubes. If you want it to be watertight and cover the o-ring on the body tube you may need to shorten the threads slightly by sawing or filing off the top of the battery tube.
The old RRT01 also legos with a Convoy S2 tube, IIRC. But it requires sanding down the tube threads to make it short enough for a good fit. Or dealing with exposed threads and no waterproofing.
Yeah I agree with what you said about aesthetic…
That said, I got the 2019 for a review, so basically for free (is free time that free ?) so I’m not considering paying for an older model
I never tried any in the new model. The reflector in it seemed decent. Its possible this same reflector may drop in the new model. I measured it at 18mm earlier in this thread.
unmodified optic
legs wont fit into the Original RRT-01
trimmed leg sides on non-carclo triple optic for RRT-01
the non-carclo brand narrow clear optic sold by kaidomain is modified to fit without any glass lens over the optic, because the optic has a smooth face
when using a carclo 10507 besides trimming the sides of the legs as pictured, it is necessary to install a glass lens over the optic, to cover the holes on the non smooth face of the carclo narrow clear optic.
