Fireflies ROT66 Flashlight

Did you ever get your light?

I’m having issues with them for a warranty replacement. Despite their claims of IPX8 waterproof rating, I fell into a pool with it and the head immediately filled with water. I contacted them and they said they would provide a replacement head but that was over a month ago and I have yet to recieve any shipping notice. I’ve repeatedly tried to contact them but have been met with nothing but silence, unfortunately it’s too late for me to dispute the charge so right now I’m left with an expensive brick.

It’s a shame, I really like this light, it was one of my favorites but at this point I’m wary of doing business with them again.

UPDATE - I did finally recieve a message back from them, they said they would update me tomorrow on the shipping. Assuming they follow through I’m feeling much better. It would be nice if they were more communicative though.

@pooptoast, did you have a go at finding out why it was not waterproof, like a o-ring missing or so? Here at BLF people are curious about that, also because many have a ROT66 too.

I haven’t taken it apart so I don’t know. The head is still glued and the o-ring is intact between the head and battery tube. If I don’t have to send back the damaged head I can take it apart later but I want to make sure I get the working replacement first.

After a week of silent treatment I got the shipment notice today.

Just wanted to update. Yesterday I was finally provided with a tracking number for the replacement head. This is a little disappointing since it’s been over a month since I reported the issue. That said, assuming the replacement comes and is in good order I will be satisfied, I do understand that these smaller manufacturers can’t respond as quickly as some of the larger ones.

Once the replacement arrives I’ll do my best to open up the old head and see if I can figure out why it leaked so quickly. I might try to test the new one as well but I’ll have to figure out how to do so without risking damage.

In general, flashlight companies should update the firmware whenever possible. The code has continued to change over time, and old build targets remain supported… so it should be pretty easy to do the update any time a new batch of drivers is produced.

Over a month of waiting, yikes. Glad they got back to you. :+1:

I wasn’t so lucky. Mine arrived defective and after many emails he never sent the replacement. I managed to get a paypal refund.

No more 219B option for the remaining ROT66s. The E07 is now the only Fireflies light available in 219B. I asked if the updated ROT would have 219B but haven’t heard back.

I got my rot66 in the mail today. It was flickering and couldn’t ramp up but after cleaning the contacts, adding a paper spacer to the tail cap, tightening the battery carrier screws and tightening the head and tail cap enough to be a PITA, it finally operates normally. The Nichia 219 color rendition is splendid and Anduril is such a intuitive and fun interface.

I guess that’s why V2 uses a contact ring instead of a battery carrier.

Asking this before pulling apart the light. Is there a mode in Anduril for the ROT66 that has ramping functionality, but no specials modes (e.g. no voltage check sunset, ect, no strobe modes, no turbo.)? Only 2 of the switch leds are on. When I do the 7 click thing to turn back on the other 2 leds, they sometimes turn on, but go out when I try to go into any of the special mods (which still don't work). I can't find any electrical connection issues. I haven't yet tried to gain access to the glued driver, but it feels secure when I try to wiggle the driver spring. I think it has the version of Anduril that had a small ramping bug from moonlight. I think this because it would sometimes not ramp directly from moonlight. The ramping behavior seems spot on. So it seems the switch itself is working properly.

So, is there a special mode of operation like this and is there a way out of it? I don't really want to break out the driver if I don't have to.

I don’t have a ROT66 or know what version of Anduril it has.

It might have a muggle mode which is 6 clicks from off.

If I understand correctly, it sounds like it should be able to get back to normal operation by clicking 6 times. It may just be in muggle mode, which has ramping and not much else.

Thanks Jason and TK. That sounds like what I stumbled into. I'll try the 6 clicks tonight.

Me either. I got a response promptly when I first contacted Jacky and he asked me to send a video, which I did. That was several months ago and he hasn’t answered any of my emails since then. Very disappointing.

Did the 6 clicks as suggested. That brought back the special modes, but now I have no ramping. Just a super low moonlight mode and a very bright (maybe even Turbo) mode. Reread TK's Anduril Manual , but I'm still stumped. Anyone have a suggestion to get ramping back?

Explain what it’s doing. You say you have no ramping, but somehow there are 2 very different brightness levels?

How are you changing the brightness levels, by a double click?

Maybe you are in stepped ramping mode and somehow changed the number of steps to 2.

Try turning the light on and do 3 fast clicks. This cycles between ramping and stepped ramping.

Turn the light on, then click 3 times. If I understand correctly, this should get smooth ramping back.

(I’m guessing you’re in stepped ramping mode with the number of steps set to only 2)

If you’d like to configure stepped ramping mode for better results, this may work:

  • Turn the light on.
  • Click 4 times to start ramp config mode. (The light should blink once, then flicker for a few seconds, then blink twice, then flicker, then blink three times, then flicker. Each flicker is a chance to enter a value.)
  • At the first option, click 1 time to set the floor to the lowest level.
  • At the second option, click 1 time to set the ceiling to the highest level.
  • At the third option, click 7 times to tell it you want 7 total steps.
