I need a very portable P60 flashlight, powered by 1 x 18650. So far the shortest ones I could find are 13cm long. Does anyone know of anything shorter?
This here is my smallest 18650 host, which fits a p60 pill. Click
However, it's not a real p60 host, since the reflector is smaller and the p60 pill fits without a spring and goes into the threads in the body.
You have very little to work with.
P60 modules are X big.
The bezels are pretty much as small as you can make them.
The 18650 is Y big.
X+Y is pretty much fixed in size.
The tailcap is all you can play with.
May I suggest a compromise? A FiveMega 1x18500 host from Nite. As Nite points out, "Single 18500 is only 17mm (5/8") longer than 16340 but well over twice the capacity." It also will deliver slightly higher voltage under load.Thanks, you are right. Before I give up completely, I am going to try a CR123A P60 host with a 16340 3.6V 1000mAh Protected CR123A Battery. This might be a little underpowered, but, hey, it's a hobby.
Where did you order it from? If you got it from KD then I think I know which one you ordered. I ordered one (L2M R2 direct drive high/lo/strobe) a while back and got it a couple weeks ago. The one I received has one of the counterfeit tailcaps on it and is not bored to accept 18mm cells.
KD SKU=S008288
I do like the direct drive module and modes. The strobe isn't as fast as most of them. I use the AW 16340 cells in it. It came as pictured with a wrist lanyard, flat stainless bezel. The tailcap has a recessed button. From what I have read on here that tailcap is not a true Solarforce. It works fine without any complaints though.
