There are some differences in this batch too. A couple of them don’t have the prettiest beam, some yellowing in the middle of the hotspot compared to the rest of the beam. Only one out of ten is above the BBL though. I also ordered some more from GB so we’ll see what the new batch looks like.
However, the tint shouldn’t matter too much because you shouldn’t EDC or use these lights excessively anyway. Only use them for calibration.
I never EDC the few lights that I use for calibration, I keep them treasured in a holster to keep the lens clean and only take them out for measurements.

Pls
Interested, I’m in for a kit, Thanks!
Interest list updated.
I’ve got 20 Convoy S2+ from Gearbest’s EU warehouse coming in and they will hopefully arrive next week. I’ve got enough BLF348s for the first 10 on the list now so they will be served quite soon, but have ordered 12 more from China.
edit: forgot I already sent one BLF348 light to an early bird
I’m in for a set please.
I’am in thank you.
I am in for a set olso.
Please and thank you 
I’m surprised the tint in the same batch of 219b emitters can range from –0.0045 to 0.0024 and the tint from 4568k to 5119k. But fortunately all of these have better tint than the average 219c.
Are you going to send them based on the number? Since I’m number 5, I would be happy to get 1105 
These will be sent in random order. And the number 1101 is already out so you would’ve been out of luck anyway 
I’d pay a bit extra for # 1107……
These are gonna be great & very useful. Thank you again maukka!! 
Oh darn. But at least these should be better than the new Gearbest 348 that probably have duv 0.004+
There’s more to the light quality than just the hotspot where the data is measured. It might look perfect on paper, but another sample could be better overall. So I don’t feel comfortable promising a golden sample which doesn’t turn out to be one. Certainly I’m not going to charge extra for those.
Yeah, some of them do look subjectively better than others which just goes to show there are big sample differences - part of why this thread came to be. However, ranking them in order from best to worst is counter-intuitive considering their purpose.
Okay, what the heck is duv and why is it important?
I am clueless. :disappointed:
Duv doesn’t matter for these, but it means the distance the tint is from the black body radiator. Bigger number = more green/yellow. Lower (negative) number = pink/magenta.
Duv, R9, and TM-30-15 are the values I look at the most from Maukka’s test. Even more so than the CRI. I also look at Rg when the CRI is very high because I like to see saturated colors.
In general, I like to have 0 to –0.003 duv for neutral tint and –0.003 and below for warm tints for indoor use. But like Maukka said duv doesn’t really matter for these since we are not going to edc them.
