Need beam shots of that E21a mod Silly maybe compared to the 219b sw45k.

best I can do until daylight, which helps my iphone auto white balance to bias more to daylight white balance (and makes the sw45k look more pink and the warmer LEDs look warmer.. anyway… here are some shots for now)

I hope this next one does not confuse people, it uses a white balance closer to incandescent

this shot may also be helpful, Im trying to compare my warm LEDs to each other

bottom lines
the 3500k E21a is whiter than incandescent, which makes it useful in the evening

and the 3500k E21 is slightly more pink than the 3500k 219b 9080 (though its hard to catch that in the pics).. I prefer the E21a to the 3500k 219b, also because I feel the E21a does a better job with making reds and blues pop.. I was a bit disappointed with the sw35 9080.. a bit too yellow

I especially like the 3000k 219b, it has a nice sunset orange effect, not really easy to capture in the photos.. Im not really that fond of 3500k myself, though I know it is a popular option, so Im experimenting..

I like the sw45k and sw45 for daytime EDC

the warmer LEDs are fun in the evening, before bed, on the nightstand, in full darkness.. they are closer to firelight

I like both choices.. a cooler one, and a warmer one, for different scenarios

===

and some lumen data before and after the e21a mod

Initial V11r lumens on 16340 w
6000k low CRI XM-L2 was 0.01 low and 420 lumens max (spec is 1 lumen low, and 570 lumens max w 16340, neither spec was remotely accurate)

after the swap to
3500k High CRI E21a, 0.02 low, and 255 lumens maximum, that is a 40% drop

I dont mind giving up lumens for CRI the color rendering of the E21a makes me very happy.. totally worth it.. I seldom use more than 100 lumens.. the rest is gravy

since Unheard is OK with the tint of the 219c, I think your link to the 16mm board w 219c is a higher output option.. as long as hes OK grinding down the diameter of the board to fit the 2019 RRT-01

I have to admit I ordered the 10mm PCB. My last experiments in grinding down a MCPCB ended in touching the solder pads. I was never happy with that, ordered another, smaller board and had some fun centering it (SST-40, M20 Warrior S with SX pill). Amazingly, all worked well. Yes, I’m a novice here Blushing

He offers a led reflow service, I think for a dollar.
He also has a store. https://www.virence.com/shop

Thanks! And wow, that’s more or less a symbolic price.

yes
the post office makes more than Clemence does on one of his impeccably lapped copper boards with a reflow of a tiny flat E21a pre mounted

Public service announcement.

The short clip on the Original RRT-01 can remove the anodising from the edge of the head tube when changing batteries. Inserting a business card, or lifting the clip when opening and closing the light, can prevent this.

Strobe discovered
in some of the Original RRT-01 from the recent group buy

credit to moderator007 for reporting this one.
The units with no strobe, say RRT01 in the serial number. as in the top light in the photo:

In the top RRT01 the sn looks more like a date code to me with the letters and numbers.
The bottom one with strobe and sos just uses a plain number for the sn.
I suggest giving your RRT01 a test. Turn it on in about med then quickly to high and back to about med, then back to high. More less when the light is on twist the control ring to high twice quickly or three times. If you have the EYE10 driver you’ll get some flashy modes that are infinitely variable in brightness. Wink

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 Big Smile

Im posting to consolidate some 18650 tube options for the Original RRT-01

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.

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.

@Firelight2, That is not correct.
I just bought an Astrolux S41, and its 18650 tube is NOT compatible with an RRT-01. The threads bind, and the light does not work.

Ah crap.

I have an 18650 tube that I thought was from an E14 whose threads perfectly fit the old RRT-01. The threads do not bind and the light functions normally. The tube has too many threads so some are exposed, but a little time with a hacksaw and file would fix that.

I thought the tube was from my E14, but failed to double-check. Must’ve been from a different light. Maybe a BLF A6. I’ll double-check and report back.
