Fireflies ROT66 Flashlight

lol. Basically I have a few friends that got inspired by my flashlight collection and whenever I see something super interesting, I let them know and see if they want to buy it. If they do, they just pay me back the cash and they can avoid the hassle dealing with the online transaction. This friend who just got the ROT66 219B is a 5700k fan. He seems to like the 4500k ROT66 but hasn’t compared it side by side with his other lights yet.

I bought a 4xE21A 4000k Tiara Pro from Clemence. The tint and color rendering on that thing is perfect. Also the Tiara Pro is regulated even on high mode so I can run it with 500+ real lumens continuously, which is great as a work light.

My ROT66 (nichia) is from the first batch with GITD and is prone to cut off with bumps but it doesn’t bother me.

Until now I never found a true rival to an HDS with Seoul SSC P4 high CRI. The ROT66 looks green compared to the HDS which seems to show deeper or more saturated colors. Red, blue, yellow, orange, etc look better, more natural than with the Nichia 219B SW45K.

Jk skv. I know this rot66 doesn’t make over 10,000 lumen, but the tint, size, quality, and firmware make it more desirable light. we got atleast 5 people that bought 2 or more rot66 including me…

My rot66 is still stuck in oversea. Will update.

DHL was early.

The SST20 4000K has a nice tint. It looks very similar to a 219B 4000K, so I think people will be very happy with it. I personally think 4000K looks yellow, even when it’s a good 4000K tint, but a lot of people really like it. I’ll try to get some beam shots later, to see if my camera picks up anything weird.

The aux LED board is wired to BAT+ and BAT-, so it does not turn off… even while the main emitters are on. I’m hoping I might be able to convince Fireflies to attach it to the button LED pin instead, so that it can be turned on and off by the firmware. I need to test that first though. So far though, here’s what it does:

  • 3.3V or above: blue, with both outer rings of LEDs on.
  • 3.0V to 3.3V: Red, inner four emitters only.
  • below 3.0V: Off.

I measured standby power usage too…

  • BLF Q8 standby, button LEDs in low mode: ~30 uA
  • BLF Q8 standby, button LEDs in high mode: 100-130 uA
  • ROT66 without aux LED board: ~120 uA on “high” mode (all 4 button LEDs at full power)
  • ROT66 with aux LED board, 4.2V, pots trimmed to maximum power: ~620 uA (blue)
  • ROT66 with aux LED board, 3.3V, pots trimmed to minimum power: ~230 uA (blue)
  • ROT66 with aux LED board, 3.1V, pots trimmed to maximum power: ~350 uA (red)
  • ROT66 with aux LED board, 3.1V, pots trimmed to minimum power: ~210 uA (red)
  • ROT66 with aux LED board, 2.9V: ~100 uA (aux LED board shuts off below 3.0V)

Based on these numbers… The standby time, with 3x3000 mAh cells, should be anywhere from 1.5 years to 9 years.

I haven’t taken things apart yet, but that’ll happen soon.

There are three rings of aux LEDs, each with their own pot to trim brightness, so in theory it could be RGB and it could indicate voltage more precisely. I’d like if it did this instead:

  • Blue above 3.8V.
  • Green+blue from 3.6V to 3.8V.
  • Green from 3.4V to 3.6V.
  • Red+green from 3.2V to 3.4V.
  • Red from 2.8V to 3.2V.
  • Off below 2.8V.

Or maybe just have rings turn off as the batteries get lower…

  • Red+green+blue above 3.7V.
  • Red+green from 3.3V to 3.7V.
  • Red from 3.0V to 3.3V.
  • Off below 3.0V.

Or something like that, anyway. There are several ways it could go. I’m not sure it can change, but if so, these are some ideas for what to do.

I have a request to the owners of ROT66. Can anyone of you screw the battery tube backwards? I have the impression that the pattern on the pipe will look nicer.

Yes you can……

Well, it’s normal. And I wanted the tube reversed

Apparently I reversed the tube when I first lubed the threads and did not notice :person_facepalming:

Hmm, however, it is not better :frowning:
It is a pity they did not do it symmetrically, because now it looks a bit like a bottle cap. Yes, I know, I’m picking on…

I’ve been keeping my ROT66 tube in the reversed orientation. I think it looks better that way, and it seems to have no effect on performance.

Jack has checked on the shipping of my lights for me. Thank you Jack.

SST20 10W NW 4000K CRI95 came in today. Very pleased

Has anyone or can anyone post comparative tint beam shot images for a ROT66 Emitter type: Nichia 219B-V1 R9080 versus the SST20 10W NW 4000K CRI95? THANKS!

Can you confirm whether it has Anduril installed?

This one does not have Anduril :cry:

I just got a 14x7135 model, so I haven’t sent the 14x7135 firmware yet.

I just received my Nichia ROT66 with the Aux LED’s. Beautiful light! Impressive if it can reach 1.5 to 9 years with the auxiliary LED’s illuminated as measured by ToyKeeper.

One thing I can’t get straight is the UI. I can’t seem to get into the strobe modes with any combination of clicks directly from off. I can double click to turbo, then double click to get to strobe. If I double click one more time quickly it goes to a bike mode. That is all I can access. Is this normal for this UI or is there another way to go through the strobe modes?

I assume you have NarsilM.

In ramping mode you do have to double click to go to Turbo and then give a pause and then you can double click to go to strobe. At this point you should be able to cycle through all 5 blinking modes by pressing and holding and it will go backwards through the blinky modes.

When you first go into the strobe mode you’ve got 1.2 or 1.4 seconds to click again which allows you to cycle up through the levels.

You can check out my video of strobes in ramping here.

Here’s a video of the newer NarsilM v1.2 strobe modes.

The only difference is the newer versions allow you to go past the first strobe mode back to the 5th blinky mode instead of turn off.
