Fireflies ROT66 Flashlight

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.

Thanks again Jason and TK. I was just logging in to answer Jason. The behavior is like what TK suggested with 2 step ramp. I click to turn on. I get either Moonlight or Bright depending on what mode I last exited. I press and hold to change to the other mode. A single click turns the light off. Three clicks doesn't change anything. I tried several times varying my timing.

Maybe 3 clicks doesn't work when there are only 2 steps. I will add steps as TK suggests. Maybe that will allow 3 clicks to work. I'll report back. Thanks again you too for taking the time to help me out.

If you click 3 times to change the ramp style, it won’t immediately change the brightness. It should just give a very short “blip” at the end where it turns off for a split second. Then if you hold the button to try ramping, it should adjust the brightness in a smooth pattern.

That did the job. Thank you ToyKeeper.

Well, I finally got my replacement head, turns out it was shipped to the wrong address and it did not have enough postage so I had to pay another 5 bucks to pick it up. Unfortunately that’s where the “good” news ends. The head that arrived is all banged up, dented and scratched. I put it on my light and it doesn’t work. I have three fresh, fully charged cells in it that work fine in other lights but I’m getting a low battery indicator on the light, it flickers on and off and the interface is unresponsive…

So I give up, this light is a complete waste. I’m done with Fireflies, their service is terrible and their lights do not deliver on what they promise.

That sucks. It seems weird that two heads in a row would have been faulty.

The only suggestion I have, which maybe you already tried, is to put a thin shim of some kind between the battery carrier and the tailcap. Some people had problems with the battery carrier not being pressed into good contact with the head.

What batteries are you using? Are they the same set you had in when you fell into water?

That is 100% possible.

You may have had a bad carrier.
