Yes, there are still artifacts but still so much better than the stock one with pink circle hahaha. Also the beam transition is way better
Did you get the same increased output?

With the beaded Yajiamei
0 sec: 1344 lm
30 sec: 1284 lm
1 min: 1245 lm
2 min: 992 lm

Measured again with the stock optics since the original test was done with a DIY sphere
0 sec: 1135 lm (old measurement 1090 lm)
30 sec: 1082 lm (old measurement 1045 lm)
1 min: 1051 lm

So an 18% increase. Would probably get more with a clear optic, but I’m not going to use them.

Correct, the plain tight TIR produces the most OTF lumens 30ish% in my case.
With Prime max angle for max OTF output is < 20°
With Wizard ax angle for max output is < 60°
The reason is the unusually deep recession in Prime’s lens. It’s not too severe in Wizard because the bezel isn’t as tall as Prime and it’s countersunk.
I use 5° because it’s my sidekick for occasional medium thrower, 90% of the time I use my Tiara Pro for hiking/EDC.

I’ll be trying the 5 degree and XHP35 HI for mine. I’m hoping to get 250m+ FL1 throw with nice tint and 80 CRI.

Can someone confirm that it is, in fact, brightest for city?

It’s right there. In white and black. How can you argue with that?

That really depends on what city we are talking about. In my city, this most probably is the brightest. But in Texas it would be just another ordinary LED flashlight. Especially if you live next to Texas_Ace and DBCustom.

Hi there,

Thanks for all the information on this; I’ve ordered a variety of those optics to experiment with, but I’m having real trouble getting the bezel off!

I see you have a bolt with a triangular head – did you make that yourself from a hexagonal head? I’ve tried strap wrenches, but I can’t get them to grip enough…

Any advice gratefully received!

Cheers

Yes, 100% DIY stuff

I also got some of the beaded Yajiamei optics for my Armyteks. I so far have tried some of them with my modded Prime C2 (Nichia 219B-V1 sw45 R9080). The output increase is very obvious! The 10° optic does not create as smooth of a beam profile as one would expect. The 15° is much better, but the edge of the corona is yellow. The 30° optics creates a very even tint, but I think it decreases the throw too much. I will use the 15° lens in this light.

All of the tested lenses create a pronounced, triangle-shaped corona. EDIT: This is caused by the notches in the bezel.

I will soon test some wider variants with my modded Wizard with the larger Samsung LH351D LED.

5° XP Yajiamei creates nice beam profile with no artifacts. Much better and throwier than stock Prime.

Clemence, could you use the oem glass with this 5° XP Yajiamei lens?

AFAIK no, because this XP lens is a bit taller

Yes, the original lens fits fine at least without the gasket which I found made the beam worse.
