Fireflies ROT66 Flashlight

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 :wink:

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.

Great!

Just received my SST20 6500k head replacement for the faulty XPL version.

I measured it at 7000 lumens bang on. The XPL measured around 9000 with 1 LED not working.

Wow, 7000 lumens, that’s high relative to the XP-L. How long can it last in Turbo before kickdown, is the lumens drop/sag quite a lot? eg at 30 sec, 60 secs.

Got my ROT66 XPL hi today. I thought, wow, not only nice looking but so light with three batteries. Then I unscrewed the cap and no batteries lol.

You should contact fireflies… they probably forgot . Lol… I should get my rot66 sst20 today…

Almost take one month to get here…

Yes I got my rot66 sst20 cw. Took almost one month, but it’s worth the wait… the light is included with the aux led and narsil v1.2. I heard newer version are shipped with Anduril…

I measured the lumen with TA tube. I got 6800 lumen with samsung 30q, and 7000 lumen with sony vtc5.

My XPL measures 2,000 lumens more than my SST20 CW and that’s with 1 LED not working, does the SST20 have any advantages over the XPL?

I don’t have a xpl version… so I can’t answer it… sst20 is cheap. I paid only $66 with the coupon code…

Nice. I didn’t get a lanyard or holster with mine. Are they supposed to come with them?

I ordered it around September 12th… i guess it’s all included it, even the aluminum tailcap.

Supposedly the sst20 has a nicer tint with higher CRI, but sacrifices a bit of output compared to the xpl-hi.
