I have a custom Vinz drop-in for sale. This has seen very little use as it was in a back-up light, maybe two 18650’s have been drained through it.
Here is the description from Vinz himself of this drop-in when he shipped it out to me:
1. Massive drop-in with optic – neutral (5000K) XM-L T6-3C – medium current – two modes with fast mode reset (0,3 sec) – to get in the low mode you need a double tab (fast half press followed by a full press).
