Fireflies ROT66 Flashlight

No, but they are on the D4S

I will get FF to look into it.

My ROT66 didn’t have Aux-LEDs, but my D4S has. When the D4S aux-LEDs are configured to “High” mode, they’re nearly as bright as the main light on the lowest “Moon” mode (maybe 1 lumen or a bit less)? Certainly enough to walk around a dark room with.

I wonder how the ROT66’s Aux-LEDs look like (does it also have a Low and a High mode?)

The D4S aux LEDs go from about 30 uA to 1000 uA, on low and high. This is controlled by the firmware.

The ROT66 aux LEDs go from about 200 uA to 600 uA, ish. This is controlled by a screwdriver.

Ordered one “glued”, as it was going to be a gift.

SST20 4000K

All emitters come on when the light is cold. as soon as it heats up one emitter shuts off. And then another one starts giving up. So after a few seconds on turbo, two emitters are off.

FF definitely need to step up their QC game :weary:

So this has turned into a test of the FF 3-year-warranty/customer support.
Sent them a mail three days ago, no response yet.

PM him on here. I had a cosmetic issue with one of mine and Jack went out of his way to do anything he could and there was nothing he wasn’t willing to do. This was just recently.
I’m sure he just overlooked your email with all that’s going on.

does that only happen on turbo? Like normal ramping it’s fine? Always the same two?

He’s sending me a battery carrier to see if it fixes my battery drain problem. No charge. No hesitation.

Always the same two.

Happens with regular ramping at lower levels also. As soon as the MCPCB heats up, they start failing

FWIW I just got a PM regarding my post :+1:

I just got my rot66 xpl hi 5000k… i bought the one with the scratch to save some money… the scratch is just on the bezel. i cant believe sony vtc5a give 1000 more lumen than samsung 30q.

Sony vtc5a 7300 lumen
Samsung 30q 6000 lumen

The 30Q is a nice mix of high capacity and still high current. Capacity and current is always a trade-off. If you don’t mind less capacity, you can get higher currents. For example, the Sony VTC4 2100mah can deliver even higher currents than the VTC5A at around 30A continous. So you just choose what’s best for you.

Hey guys,

Can the aux LED potentiometer be accessed on a glued ROT66? Or do you need the unglued version for access? Thanks.

You would need the unglued version for access.

This is one cool light, just got my champagne sst20 scratch+dent. Tint is spot on at 4K. Ideal beam and tint for a Mtn bike light!

Warranty update: FF are shipping a new head :+1:

10/10 Customer service :beer:

I received my ROT66 today, black Nichia 219B option.

Normally, I’d say the 219C’s in my D4 look about as neutral as one can get. Compared to this ROT66, a hint of green tint shows up in the D4, while the ROT66 does lean ever so slightly pink.

I’m enjoying playing around with the many features of Anduril.

With as well this style light tail stands, I also decided not to wait before making a diffuser for it from a dead A19 bulb:

very impressive Customer Service as I read…… speaks volumes

Has anyone sourced a diffuser yet? I am looking for something with a pretty snug fit. Thanks!

The diffuser Neal is selling for the GT Mini is a bit “loose” when used on the GT Mini, but it actually fits quite snugly when used on the ROT66 instead…

onieanjal - Is my picture showing up for you, two posts above yours?

Cutting the diffuser from an LED light bulb down to rest on the ROT66’s head like I did should be pretty simple if you have a Dremel, hacksaw, or other means of cutting plastic.
