Great pics. Looks like another one to add to the list of lights I want badly.
Very well done light.
oh what a gorgeous light! Sideswitch, ramping, extension tube, anodized square treads…. :heart_eyes:
Makes me want to pick up my first “big one”…
And I agree with you that the bezel is to tacti for my taste, but that would be really the one and only thing i would change.
You said Sub-C, so I guess that normal C -Cells would not fit? because wikipedia says there 27mm….instead of 26mm of the 26650’s. And three of them would be 150mm long instead of the 130 from the 26650…hmmm can you confirm that?
Very nice the review 
2.97A on high.
- Could you measure currents for 1 cell @ 4V , 3.7V , 3.5V
- Does it has memory mode when you take out battery?
Thanks
Great photos and very helpful review!
Thanks for your efforts!!
I don't have any NiMH C cells, but Duracell alkaline C measures at 25.5mm and can be dropped in the tube (inner diameter is 26.5mm).
However, three standard C cells are too long for one extension tube. If my calculations are correct, four C cells would fit near perfectly with two extension tubes.
1. I'll try that as soon as I have some extra time.
2. Yes it has.
Thanks for the review! Just pulled the trigger.
Damm I like this light, I just promised Mrs gords I won’t buy any more lights for a while. 
Good! Up to 2 x 26650 will allow long runtimes.
I measured the current at the switch and got results of 2.97A on high and 0.05A on low.
What’s the amps on 1 battery?
Sorry for being unclear. I'll try to update that to make it more readable.
Those were measured with one cell. Two cell results were about half of those (= 1.50A & 0.025A)
Thank you the for your review! 1) The beam profile of the F22 looks a little ringy, can you confirm? 2) The F22’s driver says “LD 33” on it. Visually comparing it to the LD 33 driver HERE they look almost identical except for the second black wire the F22’s driver has attached to it (goes to the switch). The specs for the driver on the website are completely different. the can you verify at all the differences between the driver in the F22 and that shown in the link? I’m wondering if the driver linked can perform like the driver in the F22 with a little mod. 
Really cool light! Thanks for the review!
They are two different drivers, one with 3-9V input for 1 led and one with 9-17V input for 3 leds, that is clear on the Chinese forums.
Great review the !
Hikelite, do you have a link for the 3-9V version? Can it be bought separately? Is it a regulated driver?
Thnx
Any comments, can this light house 2 x of these King Kong Raised Tops?

Better recommendations? ICR or INR better for this use?
If you want to use 2x26650s in series , recommended protected cells.
Great review, bud! Looks like a real nice light. 8)
Do you have to use protected cells with this light? I have king kongs, IMR’s and INR 26650 batteries…will any of these safely work? I ordered this light thinking I could use one of these pairs of batteries!
I bought and just received one of these ROCHE F22’s with the optional extension tube. Like the OP, I immediately noticed that the second plastic sleeve (for using the 18650 calls) was absent. I contacted cnqualitygoods.com and was told that a second sleeve is NOT included. This is deeply disturbing…
- No indications when ordering that a second sleeve isn’t included, even when purchasing the 2-battery extension.
- No mention from customer service during our 3 email exchange, that I may purchase one.
- Just “sorry, the second sleeve isn’t included”.
So now I’m forced to fabricate a sleeve just to use 2 cells.
Bottom line, cnqualitygoods.com won’t be seeing my funds in the future… that’s for sure.
