I have (had?) a video of the light connected to DC supply and sweeping through 2.8-4.2V or so. I don’t remember it being regulated. The driver sure is weird though. Mode spacing stayed reasonable, though did get a bit tighter visually. Meaning it’s now medium high turbo IMO. This really helped the tint of the sst20 though.
I’ll see if I can find the any notes I had from the modding.
My measurements for throw were something like 27kcd with the resistor modded sst20 and 16kcd with the lh351. I’m going to try slicing the 351 if I ever get it back lol
Edit: posted a first impressions/review a while back…
