Decribed how a vacant C8 host was set-up to be a UV thrower , but left out the beamshot(s). Because White Walls Won’t Work With UV. Then I remembered that djozz showed us we can use the illumination of the UV light on white paper. Of course I did not have a large enough piece of white paper. But I had a piece of shelf paper that was white enough to do the trick.
On the left you see the hotspot of the C8 at 1.8m (6ft). On the right you see the result of the latest model UV Convoy S2+ at 1.8m.
I don’t have access to a stock XP-L Tiara right now, but from past measurements, with the best case Yajiamei optic, the LH351D output is about the same (~870 lumens). Adding the bezel and glass lowers output something like 5-10%, so it will end up somewhat lower than stock. Don’t take any of these numbers as absolute since they come from a calibrated shoebox and ceilingbounce, but they should be reasonably comparable in relative terms. The LH351D is a nice option to have for this kind of mod.
Eventually received my Seoul Viosys emitters so some DQG UV mini goodness today :)

What did you do? That doesn’t even look real. If I zoom in a bit it looks better, but the texture at both ends seems like something which shouldn’t actually exist.
Happy to have this thing fire up on my first try. There’s a few small tweaks I still want to make but happy with my first day progress. I’ll save the pics since everyone here’s seen a S2 and my soldering skills are HORRENDOUS.
Yeah, due to the low Vf, there is a high potential for FET-based drivers to turn single 219c emitters into smoke when used with a high-amp cell. It might be a good idea to use a weaker cell there, or use thin wires to feed the emitters, as well as un-bypassing the spring(s).
An old NCR18650A would probably be safe, if you can find one.
