What did you mod today?

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.

Ahhh, so that means the LH351D R9070 is about as efficient as an XPL R7000.

Very nice indeed. I wish for them to come so I can finally use them in my BLF Q8 like djozz, and send some 351Ds/Bs to a special member.

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.

I’m not sure what you mean?

Just saying your work is so unreal it’s out of this world.

Don’t worry, it’s a good thing. :slight_smile:

Is there a textured wall or coarse paper that is reflecting in the lens? This may be what she is seeing…

Oh this, yeah that’s a textured white mat, the only glowy thing I had to hand for a picture.
I can see how that would be confusing now :smiley:

Not technically a mod but built my first S2 today:

Convoy S2
Nichia 219C
Smooth reflector
DrJones H17Fx Driver
Samsung 30Q 18650
Tail spring bypass

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.

Sounds like a nice mod e1000. As for the soldering a hot iron and good flux makes a big difference.

Isn’t that too much current for 219c?

djozz test here on the 219C.

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.

Absolutely! HA! On full turbo (FET) the LED goes blue-ish. I have my modes set fairly safe, with the high being 2100mA and I avoid full on turbo.

Yup, that’s how it tells the world it’s on the verge of death.

Wait, What? You mean, the emitter isn’t SUPPOSED to gradually turn blue in the first 10 seconds on Turbo?

No, that means you are supposed to buy a triple Nichia 219C board instead.

I wanna learn to mod someday…

Yeah. You are real bad at modding.

How dare you run XPL2s at over 3x their rated current in your Sofirn C8F! Cree engineers must be raging at your incompetence!

I know, I’m bad about stuff like that. I’ll try to get better… :wink:
