Then you need to calculate needed Rsense. I don’t know what sense resistor 6V is 4A driver has, but if it’s R050 then calculation is like this:
U=RI
U=50mOhm*4A
U=200mV
From there you can calculate needed R for 7A
200mV=R*7A
R=200mV/7A
R=28.6mOhm.
So you need to swap in R025 for bit over 7A or R030 for bit under it. I think they are 1206 sized current sense resistors. Available from Digikey also.
im ordering in a d4s with 6volt driver to make a 3500k sliced dome 50.3 build. just for fun, bc hanks boost driver will be prohibitive for output of course. I really want to make one of the freemans 42w drivers for it, but time is prohibitive. i ahve so many mods already to do lol. Not enough hours in the week.
It’s definitely not the first (original D series, M43, etc), but it’s the first in quite a few years.
I trust Hank to make a good light, if anything it reminds me of the Maglite Solitaire. I’ll probably get two or 3 depending on price (519a 5700k dd, w1, 519a 3500k d)
The DQG Tiny AAA IV had an interesting tail design which could tail-stand and be on a keychain at the same time. I’ve never seen another light use that design though. Basically, the tail end of the light has a raised “O” shape around the edge. A small ring goes through a hole in the wall, and it can flop to either side where it fits into a notch. That allows it to lay flat for tail-standing without removing it from a keyring.
OTOH, if the info I saw is correct and this is a 2A 1-mode driver, it wouldn’t be suitable for tail-standing even if it had a stable base, because it would get too hot. That would be like 700 lumens for 9 minutes… and for tail-standing (or a keychain light in general), I’d much rather have 7 lumens for 900 minutes.
You can source the xhp50.3 HI from mouser, they have lots of them down to 2700K and 95cri. I’m currently using a 4500K 80cri HD which I dedomed to give a lovely tint. Its much easier with the .3 series compared to .2
I was specifically referring to the 3v variant of XHP50.3HI, otherwise my go-to is usually just buying emitters from Convoy. Shipping is very expensive if I buy from Mouser/Digikey
Seconding D4K (and other lights) in red anodizing, it is such a vibrant color on my D2 (and a few other lights). Only colors that in my experience come close in vibrancy and depth are Convoy’s orange and purple anodizing, and the blue on my fireflies T1R.
The end of times is upon us lol
