I prefer the kaidomain one, 1 less cell in series. If it has decent construction we might be able to do a groupbuy with a custom/modded driver that has more amps.
The Fasttech listing states 15W Power consumption which cant be right, it should max around 32W?
Not sure how good a performer the KD is, but It suggests it should operate at 32W which is what should be expected. Visually both look identical other than the printing on the sider.
It can run on two or three 18650 or 26650. Tail switch, five modes including two disco modes, PWM. Plain and solid. Nothing fancy.
The size is impressive. With the full three 26650 setup it strongly reminds of a good’old four D cells Maglite, with a bigger head… and it weights a lot. I thought a Convoy L5 or a Solarstorm DX4 where rather big lights. They look like toys beside.
It does output quite some light - to say the least. I did a quick tailcap current measurement that reads 3.2A (see correction below 2.3A) with three freshly charged 26650. That’s close to 40W which is consistent with a well driven XHP-70 (see corrections below 28W). That’s good news.
The beam pattern, output and throw distance are very similar to a FandyFire UV-S5, a triple XML, 4x18650 soup can. Rather floody but still reaching some distance by shear power. It’s quite spectacular for most people. The big head seems to do a good job at heat dissipation.
I hardly played a few minutes with it yet.
Let me know if i can answer some questions about this light.
@Jubeldum: let me look into that… The pill has two tiny holes for tweezers to grab onto. Not comfortable, but a quick try shows it will unscrew rather easily.
@Rolz: it’s hard to tell… Tail cap current with only two cells reads 4.35A (see corrections below 3.6A). The cells read 4.1V. That’s just over 35W (see corrections below 29W). Still a very good number.
From left to right: Convoy C8, Convoy L5, Fandyfire XHP-70 and Fandyfire UV-S5
The pill:
Some measurements:
Inside diameters driver side: 24.5mm and 27.2mm (where the driver sits)
Inside depth driver side: 14.10mm
Outside diameters: 28.5mm, 31.85mm (threads) and 32mm
PS: you can see there are a few dings and scratches on the body. My parcel arrived with a sticker “opened by customs”… and the extension tube was loose against the light body when they packed it back. Oh well…
