Fireflies ROT66 Flashlight

I’m really interested in what kind of runtimes we can get out of the highest regulated output for the Nichia version and if heat is an issue. I’m assuming that’s 1-1500 lumens?

Thanks for the response.

I suppose if I do buy one, I can make a simple adapter for tripod use.

I’m trying to hold off buying more lights, but this seems like such a great worklight, it’s really tempting.

I ordered a Nichia version from the GB.

Hoping I won’t regret not ordering the XPL HI version which has more throw and nearly twice the output. I was thinking the 3D tint might be too cool and the 4B tint might be too green. So I chose the Nichia, which should have great tint but won’t have the wow factor of the 3D.

@Fireflies:
May I repeat my question:

How is the bezel fixed?
Is it just screwed, or glued, or pressed …
Can I open it without damaging the light?

Edit:
One more question: can I open the switch bezel to get access to the switch board without scratching it?

steel_1024 got his off and only mentioned the driver glue but I suppose this is not definitive confirmation:

The switch bezel looks to have the little notches on the inside edge. So it looks like it’s threaded. Whether or not you can unscrew it without scratching it depends on your snap ring pliers and your skill.

As far as it being glued as well, maybe someone can tell us.

I’m able to tighten or loosen any protruding screwed (unglued) bezel with my sophisticated bezel tool:

We were refering to the side bezel around the switch.

Wait, you are the one who asked about the side switch bezel.

On the Q8:

From etex

Switch bezel, No notches, not easy to open
Looks like interference fit

Driver’s bezel fixed by some glued.
You can disassemble the MCPCB first.
Then use the Needle-nose pliers to open.

Will leave some scratches on bezel.

Well that is great. I guess I was seeing little shadows on the ring that looked like notches.

So what do you do if the switch goes bad? Throw the light away?

Maybe with the driver out, the switch bezel can be pushed from the inside?

No, can not pushed from the inside too. Very small hole.

I will try the leverage……

I’ve got a light with what may be a press fit bezel. I was thinking of sliding a dull razor blade under the edge to try and lift it. It may scratch the finish, so I haven’t tried yet.

Leverage principle, not difficult, but be careful

Will not hurt the rubber press, bezel

Thanks. :+1:

Thanks a lot!
Same principle as Emisar D4.

The black ROT66 has a black switch bezel though, painted, I guess. Probably more chances to scratch that one. I’ll try to print some plastic tool for removal when necessary.
Or I simply might remove the paint from the bezel, if scratched.

Thanks!
Just to check if I understand correctly:

1.) The lens bezel is screwed without glue?
If yes I would still like to see a statement of Fireflies if this remains true also with the production units.We have seen problems with glued bezels on later production units with other lights in the past.

2.) The driver board is retained by a screwed and glued ring?
But why do I have to disassemble the MCPCB first?

Would you mind to remove the driver boards retaining ring once more and make a picture of the board only (board can stay in place)? And what’s the inner diameter of the driver boards retaining ring? I intend to design my own board and would like to know if I can place the vias for a programming interface between spring and retaining ring.

1.) Mine is not glue on the lens bezel.

2.) Yes

The wires connecting to the MCPCB are very short.

The inner diameter of the driver boards retaining ring is:10.8mm
Here put a black plastic insulation ring
I re-solder the (+)spring so I removed it

Thanks again, Steel!
10.8 mm is narrow, might fit with a small spring, but I guess I can widen the inner diameter by 1 or 2 mm. The opening of the insulation ring has to be widened anyway.
I think I can start designing this board now. But there is also our first 3d printer waiting for launch, and the kids are pushing …

ROT66 received. SW45K R9080 confirmed, very pretty beam confirmed. Review coming up hopefully early next week.

Nice!
