The clear ano would not be my idea, and it will have huge problems running on the FET (15+ amps, on XP-G3 while 3A is sensible for a skinny light like this and already gives lots of light), but still I’m in wholeheartedly.
That is a good idea and I thought briefly about it but was not comfortable with the Battery+ being so close to Battery- (the microcontroller for example needs a connection to Battery+). In case of a short between the two tubes (for whatever reason) you’d fry the battery. With the current design the worst thing that happens is that the light gets turned on and you still can operate it by loosening and tightening the head.
djozz points at my initial thought, anyone realize how hot this will get and how fast it will do it? I’ll wager that on a good cell, in Turbo, you won’t be able to hold it in 20 seconds. (Thermal step down not inclusive, it won’t run long in Turbo in other words, not long at all)
Hey, after all a Turbo is’nt meant to be used for extended time :-p
Seeing my HC30 TA FET driven getting scorching hot in less than 30S, I can’t imagine how this one will get with 3 emitters freely fed by a 30Q !
A true Pocket rocket !
Good thoughts! The tailcap has knurling on it to improve the overall grip and also of course, to make it match to the head. The groove is just to have a clear stop for the knurling and the thickness of the wall is just as much as at other “thin” spots, so there is no decrease in durability there.
The reason the head is used to change the battery is because the head is larger which makes it easier to grip. The tailcap is very short and I think it wouldn’t be very easy to get a hold of it, especially with the clip besides it. Then you’d also have to be careful to not rotate the clip (so the anodizing doesn’t scratch off). That way I think it’s easier - construction-wise it’s also a little safer because then the driver is fixed in place, which is more important than the switch-PCB being held in place.
