My equipment is just too pro. Ikea LED bulbs and a 4 year old phone = magic.

Replied and shipped.

I’m running out of lights soon (two sets left), but ordered some more S2+ and BLF348. Also got ordered a couple of Convoy C8+ with 4000K CRI90 Nichia 219C. If someone wants check the integration properties of their sphere with a throwier light this could be a good option. It can also replace the BLF348 in a set.

Unfortunately with the C8+ the package will exceed the maximum thickness of 30mm for a small letter so the shipping costs will be a little higher. Around 7-16 € more depending on the buyer’s country. Also the light itself is pricier than the other two. That’s why I just got two for now. S2+ and C8+ together as a set would be 81-90 €.

One C8+ measured and ready to go. On its own, the price is 50 euros if you previously bought a set.

Well, I’m finally joining the calibrated-meter club. Pretty soon, people should be able to expect much more accurate measurements from me.

Nice, are you building your own integrating sphere?

No, Dale took pity on me and is sending a nice calibrated lumen tube. It’ll put my “integrating milk carton” to shame, and eliminate the need to use my other device, the “integrating bathroom”. I also finally ordered some calibration lights to go with it, which might be here by the end of the month.

So… I’m basically joining the club because I got a kick in the pants. But, like, in a nice way. Smile

I didn’t think Dale had a spare integrating sphere/lumen tube. I think TA did. That’s why I wasn’t sure. Anyway, I see Dale is talking about building a new one. Maybe he’s giving you the one built by Manx Buggy. If so, it is a the pvc unit with no diffusers. It tends to read a bit higher for throwy lights compared to floody ones. Then again, he might have built you one from scratch. Oh well, tell us about it when you get it. I’m curious. Thumbs Up

More specifically, Dale and the brothers R decided I needed one, so they made it happen. If I understand correctly, it’s a brand new lumen tube and meter, full of diffusion sheets, calibrated with maukka lights, which should read out lumen numbers directly on the meter with no multiplier.

Of course, things may settle and shift a bit during shipping, so I’ll most likely recalibrate it myself to be sure. I needed to get some calibration reference lights anyway… so both tube and lights are on the way.

It’s a pretty huge upgrade from my current gear.

Maukka I was wondering. Do you have to recalibrate your sphere each time you use it with that “Lisun’s SLS-10W standard light source”. The reason I ask is some how I have found my 3” lumen tube way out of calibration again and I am not sure why. Everything is in the exact same place it has always been. The tempreture in my shop is up a little right now, but for most every test I do I put the lights and batteries in the house for a day before testing. I understand that absorbtion has to be calibrated for, but I’m even getting a different set of numbers on the same lights (such as the calibration S2+).

In Him (Jesus Christ) was life; and the life was the light of men. And the light shineth in darkness; and the darkness comprehended it not.

I always calibrate befoore taking measurements. Not with Lisun bulb but with three calibration lights to make sure everything is in order. There is usually some variation (a percent or two maybe) between sessions but as long as the correction factor between the lights doesn’t differ more than half a percent, everything is go. So there hasn’t been any lomg term drift for me and I also use an S2+ as one of the cal lights.

Dust is an issue I have, I have to clean my sphere every week or so to keep readings the same.

I have a SWM D40A (I measure the highest regulated setting) that I check my sphere with, and it reads between 10.95 and 10.85 (before multiplier, it is around 550 djozz-lumen) for years on end now. So it should be possible to stay consistent with home-made light measuring contraptions.

I do remove dust and grit inside the sphere every now and then with a vacuum cleaner, although some visible dust does not alter readings significantly.

Maukka… that set-up is DOPE!

lol what do you do for work? I’m very curious what professions utilize integrating spheres and the rest of your equipment.

I also one day want to build a lumen tube.. maybe a sphere.. lol I’m pretty ambitious but those both being a long time away I just wanted to say it’s very cool you taking the time to provide proper calibration equipment to the forum, Thumbs Up Beer

He spent thousands of dollars for this equipment, not as part of his job, but just as a hobby. Cool, huh?

ARRRRRRRRRRRR!!! I didn’t catch that until just now…… 5.XX volts in the battery left. Sad The readings were not only off they were scattered. They were all high, but not even by the same percentage. That pretty much took care of it. Now to go back and make updates all over the internet.

Hey guys, am I calibrating my sphere based on the MID mode from (low,mid,high) on the driver?

Thx, was sanding down my sphere and wanted to make sure before I taken too much material off.
