WTS: Calibration lights for DIY integrating spheres / lumen tubes - 67 € -

Interested.

Missed that because it was on a picture.
Thanks for clarification.

Added you to the list and will PM you when your kit is ready to be shipped. No need to pay anything just yet.

Bump. With all the drama around here lately about calibrating lumen tubes I can’t believe there’s not more interest in this offering. Lots of us have measuring devices - group-buy sphere or tubes, homemade boxes, whatever - and want them to all yield comparable measurements so we can have more meaningful discussions. This is the best way to accomplish that goal, and offered for a very fair price.

Really happy to see this idea coming to fruition so quickly. I’m definitely interested in a kit. I agree with emarkd, this should have way more interest given all the recent output measuring drama!

So 64 euros is $71.62 US dollars right? That’s what a online calculator came up with. Well I used another one and came up with $75.18 US.
Could you clarify what the price would be in US dollars please. I’m pretty sure I’m in for the set just don’t know what the Paypal payment should be.

It’s $75.17 USD right now. You’ll probably pay around 2.5% on top of that for the currency conversion from either your card or PayPal. The PayPal payment will no doubt be in EUR so there is nothing to work out.

Just choose sending euros in Paypal and they will do the conversion (with their conversion fees like Bob_McBob said). If you want to pay in USD it’s $78.

I will take cryptos (BTC, ETH, LTC, MIOTA, VET) as well.

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:

Count me in.

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
