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’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.
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.
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.
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 …
How is the beam profile compared to the Astrolux MF01 Maukka? Is it a nice broad hotspot where all the lumens concentrated in that hotspot with minimal spill? Or is it slightly different?
Also when you do the review can you tell us what the highest fully regulated output is and if the light gets hot at all on it?
I’ll take beamshots comparing it to the MF01 for sure. Highest fully regulated output would be the 7x7135 level, which should be somewhere around 500-600 lumens. However, you would have to switch to the mode groups from the ramping UI to reliably select that level. I ramped the light to ~600 lumens and I’ve been running it for over an hour and it is regulated.
The original driver designed by Lexel had much more of the 7135s, I wonder why Fireflies decided to use less of them? My guess was either to cut costs or they thought it wasn’t necessary to have the higher regulated output levels because the host couldn’t take the heat.
Thank you for confirming for us! Looking forward to your review! Good to know that the CCT is 4200k to 4300k. I was afraid the ultra low duv might make it overly magenta but lower CCT should make it more rosy than magenta. I might still get one to swap in 4000k 9080 though in the future.
BTW, how did you get it so early? Did you buy it or did they send you one for a review?
