21700 cell, 40 mm head, not very long - nice format, must feel good in hand
e-switch
USB charging
push-pull action
probably - Lumintop’s good overall quality
Lumintop chose to use a partially frosted lens to smooth out the beam. Fair choice. I suppose it avoids the problems with a hole in the beam in intermediate zoom positions.
With the versatility that zoom1 offers it could easily become one of my most used lights.
There are several things that could make it better and most seem to be achievable with modding skills somewhat above mine.
Lumintop, if you go for beam quality - how about adding high CRI options?
Narsil / Andruil would be awesome
XHP35 HI seems like a natural choice for this light with its better efficiency, better throw and easily double Turbo output ( GXB172 ).
Type C….Lumintop offers it in several lights already and I wonder - why not this one?
How about adding a powerbank function?
With these changes….that would be nearly a dream light.
I dropped in a white flat. Had to sand the mcpcb a tiny bit. It was a 16mm, needed to be 15 or so to fit the cap that covers it. Super east mod other than the sanding. I used a Dremel with sanding wheel.
Kept the driver the same. Long press to off kinda sucks.
Meh, still. Hotspot, zoomed out, is still too big. Not nearly zoomed in enough to get a clear die shot. Needs another few mm of outward movement.
I got 16,314cd with the oslon. Didn’t bother with the stock emitter.
21700 will not fit out of the box, gotta buy their tube. Quality is good, just not happy with the short zoom distance.
Removing the optic and holding it further from the emitter yielded 59kcd with the zoom1. Beam pattern was nearly identical to the cometa in this configuration.
Lower current than the l4p drivers i’m using in the other lights.
This was very close to the optic being flush with the end of the head (bezel removed), and zoom fully extended outward. I don’t see a realistic way to mod it without a new head.
With an aspheric lens type zoomie, you can easily lose 50-75% of the total lumens when cycled to spot mode. This is because the light is emitted from the LED in a wide cone, and most of this cone hit the sides of the sliding bezel rather than the lens when the bezel is extended for spot mode.
With a zooming TIR mechanism like on an LED Lenser, the light loss when cycling from flood to spot can be as little as 0%. This is because in theory all parts of the LED’s emission cone are collected by the optic and directed out the front in both flood and spot positions.
However, not all LED Lenser type optics are created equal. I’ve seen some where there is no visible lumen loss in a ceiling bounce test. But I’ve seen others where significant lumens are still lost.
I take it all back… 464 lumens at zoom out, followed by 388 focused tight. 83.6% or a reduction of 16.4% Battery hot off the charger in both instances.
