Mini Review: Jetbeam Jet-II MK

LED Flashlights – General Info CR123A Flashlights
1

4 modes a​​nd no mode memory, always turns on in moonlight.

Cannot detect PWM (swinging or camera).

Build as nice as Jet-I MK but threading is nicer, so you don’t have to untwist head as far out as the I-MK to securely turn off. Threading came lubed but slightly dirty. O-ring size/thickness is fair.

Pocket clip keeps rotating in the groove and is a real PITA, makes one-handed operation next to impossible. Clip also grazes the knurling on head while rotating or head tightening/loosening.

Beam is cool white (has a very slight tinge of green) and hotspot is wider than that of Jet-I MK but runs cooler than the Jet-I on max mode despite more lumens (probably due to XP-L HI vs XP-G2 efficiency?).

Tiny gap between head and SS bezel is an eyesore (2/2 samples).

Opinion: I really miss the mode memory feature that the Jet-I has, don’t really know why Jetbeam messed with a good thing. This thing is really well-built though. Despite the XP-L HI and more lumens, this cannot out-throw the Jet-I probably due to a shallower reflector and the orange-peel. Spill areas of beams are similar with the Jet-II being brighter generally, across all modes.

Jet-I MK and Jet-II MK.

IMO, the Jet-II MK doesn’t make sense if you have the Jet-I MK already unless you like moonlight mode and the PWM on the Jet-I bothers you too much. The Jet-I throws further, has 23% more capacity in the 14500 format (although might suffer on runtime on high due to emitter efficiencies?) and can take AAs. The pocket clip is bad but workable and not as irritating as the II’s.

Thanks for the review!

From the looks of it the driver is not pressed from behind with a ring, most probably held by vertical contact posts soldered to the mcpcb, like some of the nite eye models.

Ah, wouldn’t know about that, can’t see a seam in the head, I guess it disassembles through the SS bezel?
