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.
@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.
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.
I bought some sapphire lenses on aliexpress, as far as I can check it, they are legit. This store has a good collection. Check if they are flat and the correct thickness, because they are sold as watch christals, some are convex.
thanks for the link and suggestions to avoid domed lenses
I have not actually found any sapphire listings in the 18mm diameter range (intended for original RRT-01), yet
I’m not around a lot anymore, made a lovely career change in my 50’s that’s all encompassing at this point.
Try this fellow for sapphire, if he doesn’t have what you need, he will more than likely recommend a source. I just used his lenses for a NiteCore mod last year, very happy. Be cautious of crystal thickness and also of replacements with rounded edges, you made need o-ring changes, depending on the torch. .005 matters
and thanks for the 0.13 mm tolerance ( 0.005) relevance, advance warning about rounded edges, and potential replacement O ring awareness
all very helpful
