After watching a few reviews, I conclude for myself that the Aputure MC will be too dim for my needs. The GrafiLite 2 looks promising but I think I will go with the Phottix M180 as suggested by Marcin as it serves the purpose of print evaluation but can also be taken outdoors for lighting a scene.

If anyone knows even better solutions, please share. Thanks.

The Phottix M180 seems to be "unavailable" at most places in the U.S. usually with a note that "we don't know when it will be back in stock".

Here in Germany, there seems to be only one source: photospecialist.de

They sell it for 129Ä. I just ordered it.

There's newer Phottix M200R, maybe it repleaced M180. The brand name is not very important, you can get similar lamps at different names, most of them have reasonable spectral quality.

Thank you, Marcin, you have a point there. I didnít really identify the M200R to be kind of a successor of the M180. A bit more investigation seems to confirm that notion. I asked Photospecialist to change the order.

If you're looking for a dual-purpose light with enough light output to make it useful for image capture, the Rotolight Neo 2 is worth a look. It is more expensive, but has much more light output producing 2,000 lux at 0.9 m (dimmable from 100% to zero), is widely used in professional video and photo applications, and comes with a number of useful accessories. Though more expensive, it has come down dramatically in price since being introduced in 2017. You can easily find lots of reviews on this light.

The Rotolight Neo 2 can be used as a strobe on still cameras and includes HSS and built-in Elinchrom Skyport receiver for remote control. CRI has been justifiably criticized as a method of evaluating color as two lights with the same CRI rating can have very different overall color accuracy. Where LEDs tend to fall short in color is in the red portion of the spectrum, so it's important when looking at CRI for a rough guide to color to look at the R9 rating, which is quite high on the Rotolight.

Rotolight also publishes spectral data, which is something that I would like to see from any manufacturer. While it has a list price of $299 in the U.S., it currently sells for $189.

I see an LED proofing solution at JUST website. (about EUR 1.600.- inkl. VAT). So I draw the conclusion that there must be any LED vendor/producer JUST uses... Any ideas?

What are your experiences with Yuji/Waveform lighting/Soraa concerning UV ratio?

Sorry, I don't have a spectrometer could measure UV rays. All I can do is comparing their SPD (attached below). All the spectrum powers were normalized to the same luminous (according to CIE 170-2 cone-fundamental-based spectral luminous efficiency functions).

Which I believe waveform lighting and Yuji's D50 lighting contain no UV. The JUST LED Proof Light has a raising up curve at 380 nm. That might be a 365 nm LED which is commonly used on market for OBA checking. But other two lights have a natural downward curve. As you can see, these 3 lights have 4 similar wavelength peak. But only JUST LED Proof Light has a 515 nm green light peak, and narrowest band. Unfortunately, it's not my own light, I cannot disassemble it to find out any producer mark or SKU.

data calculating from SPD (base on TM-30-18):
JUST LED Proof Light Ra 97.9 R9 98.6 R12 93.0 Rf 97.4 Rg 101.8 CCT 5007K
waveform lighting    Ra 98.8 R9 90.5 R12 98.7 Rf 97.5 Rg 100.3 CCT 4955K
Yuji VTC D50     Ra 97.8 R9 95.7 R12 88.1 Rf 97.2 Rg 101.7 CCT 4849K

edit: waveform lighting SPD in the diagram is D50, D65 is a typo.

That's more than I could have hoped for :-) Thank you very much.

I will have a look for UV led strips, get me some Yujis and report back if I could find a working DIY proofing solution including UV.
