Alright sounds good to me, if pp does the conversion. I’m in for the set, just PM when their available. :+1:

Very nice, these as the same lights I used to calibrate my own sphere. I just wish I had had them a few years ago, it would of made my life SO much easier. Well worth every penny.

Plus there is a lot of time involved with taking all of those measurements for each light.

Thanks for doing this. Please put me down. I’m glad the BLF348 has a duv of –0.0025, which means it’s the old batch and not the current batch I just bought with slight greenish tint. Instead of just giving us the 30s lumens. Can you also give us the startup lumens for these?

I am in maukka, thank you. :slight_smile:

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.

22

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.

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

26

I’m in for a set please.

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 :smiley:

31

These will be sent in random order. And the number 1101 is already out so you would’ve been out of luck anyway :wink:

32

I’d pay a bit extra for # 1107…… :wink:

These are gonna be great & very useful. Thank you again maukka!! :beer:

33

Oh darn. But at least these should be better than the new Gearbest 348 that probably have duv 0.004+
