Unless money is really tight I would just sell the glued one and order a new one if you absolutely must access the bezel. It’s not worth the risk of melting the optic and other damage when you can order it unglued from the factory.
A strap wrench won’t work on the driver retaining ring.
That part probably doesn’t need glue at all. Usually the point of a retaining ring is to avoid the need for glue.
It was very difficult to open. The thread has been damaged and is no longer correct. It helped me to drill the holes deeper. As far as possible no pressure should be exerted from above to avoid damaging the thread.I used needle nose pliers, spanner and vise.
Exactly!
One problem are the conical holes
in the retaining ring which I cannot grip well with a mounting tool. Therefore I’m not able to apply much force.
This is my most expensive stock light up to now and I don’t like to damage it. If Fireflies doesn’t help I finally will drill additional holes for better grip and use the heatgun but I’m still hoping for their response. Fireflies should know a method for disassembling defective lights - or do they put them in the wastebasket?
Thanks! Bad news though. I consider this a bad design, the conical holes require pressure from above!
What do you think, Fireflies?
A hot air gun might have helped. I was not sure if the heat destroyed anything.
D’oh! I should have read more carefully. I was thinking of the bezel.
We have a few stock ROT66 with minor machining flaws or scratches available, those lights perform perfectly in function. If anyone have interested, please send me private message or email to ff-light@hotmail.com

I noticed on Facebook the other day the ROT66 is now “officially” shipping with Anduril, and the Fireflies site reflects that. Since the firmware status has been up in the air for a little while, can we can a definite confirmation all models (including XP-L) now have Anduril?
I was happy to see there is now a “no glue” ordering option. Does that apply to the driver as well?
I just got mine a few days ago. How do I check?
Check what?
Firmware, Anduril or narsilm.
Has anyone with an order number earlier than #243 received Anduril or a no-glue light? (I ordered a 219b, and asked for those options in the comments before they became standard)
Edit: I got a response; mine will have anduril but be glued. So if anyone wants to know whether theirs will be whatever, compare the order number.
Here is Anduril.
Just try something that is different from NarsilM. If click click hold goes to a blinky mode, it’s Anduril. If 6 fast clicks go to muggle mode, it’s Anduril. Try 3 fast clicks to go to battery check, then 2 fast clicks should be “sunset”. If so it’s Anduril. If it blinks 1.2 or 1.3, then it’s NarsilM. Try cycling through the blinky modes. NarsilM us strobe, alternating strobe, bike light, 2 second beacon then 8 second beacon.
Thanks for the info. So these two versions of Anduril are both configured as 3-channel (7135x1, 7135x6 or 13, FET), right? Then may I know the exact level of 7135x1 100% on the two versions? I suppose that level should be also PWM-free and can be pretty useful in some situations…
It will be even better if you are able to upload the ROT66 specific header files to your firmware trunk so I can figure it out myself 
I uploaded that a while ago, but it’s in the fsm branch, not yet merged into trunk.
Got it, many thanks! So level 65 is the 7135x1 100% on both ROT66 versions.
When going to the (stepped) ramp ceiling from off directly (two clicks), the light may regulate itself to an even brighter level (because target_level is set to MAX_LEVEL?), especially when the ceiling is set to a lower level and enough cooling is applied. However if you go to the ramp ceiling in the other ways (memorize that level and then recall or simply ramp to that level), then it won’t demonstrate this weird behavior.
Not sure if this is intended, just willing to let you know.
Good catch. Fixed.
Hadn’t noticed this during testing, since the ceiling was generally high enough that it would regulate down instead of up. The fix is a tiny patch though, and doesn’t change the code size at all.
