WTB Makkua Calibration Light

Hi all. Feeling around for someone willing to sell me their Makkua calibration light(s). Prefer US only. I’m looking for the S2+ and the 348, but if you have just the S2+ that’s fine.

Thanks

I sent a S2+ and a 348 to a friend who had a light tube and Makkua lights —calibrated mine through his —worked for me

Thanks for that, but I don’t have a 348 or S2+. I built a tube and need to calibrate it. Plus I’d like to have them if I need to do a re calibration.

Any regulated lights with known(calibrated)outputs will work —If you can’t find the Makkua lights

I know and have a bunch of lights from reputable manufacturers, but like to have independently tested samples also. If I can’t find any no worries. They make calibration easier/quicker.

Did you build a 3” or 4” tube — are you trying to make yours where it reads right off the meter or use a calibration multiplier — I just use a multiplier—I never could get mine right like the ones sold on BLF —it suits my needs

4 inch opening reduces to 3 inch. I use multiplier also, but getting the miltiplier consistent is the tricky part made easier by a calibrated light.

The transition between Throwers and High Lumen Flooders will make you crazy —- I put DC Fix on a glass shelf that helped a lot

I’m thinking of using a piece of white grocery bag (the single-use ones) ad a diffuser, but maybe not. I have a dedicated sphere for other ights. I built the tube for big lights (heads over 65 mm).
