Fireflies ROT66 review (3x18650, 9x219B)

I see… so that’s why sales of the ROT66 XPL-Hi have been suspended for the meantime. Hoping they’ll be able to fix the issues with XPL-Hi soon.

So they traced the problem to be with the XPL HI version. That makes a little sense considering the ones Vinh and toobadorz were XPL HI, and the ones the reviewers got that were fine were Nichias. That gives me a little more ease while waiting for my Nichia version to come in. Still though, aren’t those emitters very similar size? They have domes on them so I would think they’d be even easier to crush.

The xpl-hi emitters have a taller base, the white part of the LED, then the Nichia emitters. I believe the xpl-hi are 1mm tall and the 219C are 0.4mm tall.

The 3 legs built into the TIR lens is what’s supposed to prevent the lens from crushing the emitters. I guess they drilled the holes in the mcpcb too deep.

I was thinking about ordering this flashligh. I need a replacement for my Nitecore TM06.
But with this light ive seen and heard of some quality problems… So im not sure…

It stands between three flashlights, what do you guys think? in need of some input thanks guys :+1: :smiley:

Its either this flashlight(ROT66), Emisar D4S, or Noctigon Meteor M43.

I have the D4S and M43 and ROT66 on order since the first day it was announced :weary:

The M43 is a very nice light and the XPG3 measures 1,000 lumens brighter than the XP-L HI version. I am very impressed with the premium quality of the light. However, due to the size, it’s not convenient to EDC for my work, so I stopped using it. I just got the D4S and it is a beautiful light. The auxiliary leds are absolutely brilliant. I love the light. I say it is a must get for all Flashlight enthusiasts. The ROT66 is the first and last flashlight to use the discontinued 219b 9080 emitters, which is considered to have the best looking tint by HI CRI folks. You can get this and use it as a benchmark to compare with all your other lights. It also has a Lexel designed driver, which is better than the other two flashlights. Also the 3x18650 size should make it much more pocket friendly yet still have very good runtime to be practicable. It is also brighter than the D4S and brighter than the M43 with the same emitter due to the better driver. I bought two for myself since this will definitely be a collector’s item when it gets discontinued.

Thank you very much for your input.
Im not going to EDC this one though. This light is going to be used when walking our dog. So the size of the m43 for example, is not a problem since im going to have it in my jacket.
I do REALLY like high CRI flashlights though… i have a D4 with 219c 5000k 90cri, which i love the tint of…

Maybe if i order the ROT66 with 219B, and test it out. If i dont like it, i’ll order a M43 maybe?

Pretty good breakdown. As an owner of an M43, I can admit that due to its size and 4 cells, I don’t use it as much as my more practical single cell lights.

I would have to say that brighter does not equate to a better driver. The Lexel driver I am sure is great, but it’s a linear/Fet driver that is not nearly as efficient as the boost driver in the M43. The lexel driver is brighter only because it pushes the LEDs harder using FET and pwm.

My view is in no particular order:
-M43 for best efficiency and runtime
-ROT66 for best tint and CRI.
-D4S for balance of price, size and single cell.

Am I the only one who thinks that this light looks kinda cheap with the silvery tail?

Also, for 98$ there should be a screw-in plug for the thread.

This light is suppose to replace my TM06, Head Size 50 mm with a uniform body. And that size is no problem for me.
The M43 is 63mm(head) 50mm(body). Almost the same. And i can live with that i guess.
And i can get the m43 with nichia 219 90CRI.

Ive heard that the 219B on the ROT66 is very Rosy on the higher modes. But i dont know if i like that or not… :person_facepalming:
Im more drawn to the M43 to be honest.

But the ROT66 with 219B will maybe be a collectors item as SKV89 said, which makes it desirable. Hmnm…

I could buy both, but that feels kinda unnecessary since im not a hardcore collector…

I dont think it looks cheap. It gives a very nice accent to be honest.

But what i do think´is that since the SS bezel has a smaller diameter than the coolingfins, becuase it has a step from the fins to the SS bezel i think it looks kinda weird.
Maybe its just me… :expressionless:

when is the version of xp-l hi available?

it looks awful. I agree.
The aluminum Tail part should have anodizing in the color of the case

Great review there! I’ll wait for mine too!

The aluminum tailcap being a different finish than the stainless steel head looks pretty bad. The stainless steel tailcap looking the same however looks very nice. I prefer that over a same color ano’d tailcap.

It may also be relevant to include the BLF Q8 on that list, since it’s the most similar to the TM06. But for walking the dog, I’d suggest going with something a bit smaller.

I’ve looked at the Q8 now, but I really doesn’t like the look of it.

Oh, I forgot to say, I’m not walking the dog, my gf is.
So the size really isn’t a problem :slight_smile:
I bought her a Emisar D4.

You might get her some mittens to go with that. :wink:

Hahah, good one :smiley:

Someone just PM me asked for the compare beamshot between 219b & xp-l hi. FWIW, I figure I might just post here as well.

Do you mean like this?
