This is a project I’ve been working on for quite some time. The head is a spare from an old fenix E21, the tail is a P60 (specifically a solarforce L2T). On a 3v 123 the stock driver runs at .9A on low and 1.5A on high (on a Li-ion its pulls to much current (>2A) so its limited to 1x123). [if anyone has lumen output estimations that would be great!] the body was turned from 1” Al stock.
(I’m not sure how to post pic’s on this forum software so it may take me a few times).
No dumb questions- I don’t have it any more. I gave my old E21 to my father in law on Xmas eve when he needed a light (unplanned) and this was a spare head I had for it that the stock emitter burned up in so fenix sent me a replacement and didn’t want this one back.
The two things I like most about the E-21 is the good throw and the forward clicky. I run mine with a 14500 and a dummy cell. I find it runs just fine this way. The tint looks better and the output looks about double to my eye. A recharable 16350 would make this a heck of an EDC.
I got some 16340’s today, I was disappointed to see there is no low mode on Li-ion. I don’t mind sticking with 123’s but I was looking forward to the extra umph on a 16340.
Here are some more detailed photos, beam shots will be coming soon. As far as running it on a Li-ion, it’s only slightly brighter on high yet gets a lot hotter and while there is a difference between H and L, low is too bright so I’ll be sticking with 123’s, I’m working with RMM to come up with a ground switched driver for it tho.
