Indeed, I checked into having a company in the US measure some lights in a professional sphere. IIRC they wanted like $300 bucks per light, and that was if I sent them the light. So literally 10 times the money.
There’s usually no reason to measure high output lights for calibration other than having more significant digits in the number. Calibrating with a light measured at 2 lumens isn’t very accurate, especially if your tube close to 1:1 lux:lumen ratio, but 188.3 has plenty of resolution.
Lux meters are linear in their operating range and while some people are worried that their tubes read wrong on higher lumens, that shouldn’t be the case. Even if there’s leakage through the PVC, that will also be linear no matter the output. You just don’t notice it on lower outputs.
Ok, I will just start with the 2 then I would like to mention this on my Youtube channel if your up for making a few extra lights. This is really a big deal as far as I am concerned. If your ok with that I could use some help pronouncing your screen name….
The first batch of S2+s hasn’t yet arrived in Finland but should next week. After I’ve tested those, I will PM the first people on the list with payment information.
Quite a few news articles have appeared recently about the Finns being the happiest people on earth, this one seems to go into a bit more depth than most:
Seeing pictures of maukka’s workbench/space certainly helps me understand the whole concept better, as I know I’d be a heck of a lot happier if I had instrumentation like that!
Nice to see it all being put to good use for the benefit of man/womankind by sharing the peace-of-mind that comes from having properly calibrated equipment with the rest of us.
djozz should be pronounced as if I were a really cool dj (there actually is a belgian dj who is not me but who calls himself djozz) , but my actual name is Jos which is pronounced close to “ioss”.
Errr…Ummmm. I’m still a bit confused. Are you saying the whole thing should be pronounced as one word that sounds like “ioss” The D would be nearly silent? For the “ioss” the “I” would lean toward having a “y” sound?
