ССТ 5000 is not good enough. Can’t underatand why every led company starting to produce new kind of leds from low CCTSad

Probably because there is a norm (IS0 3664:2009) in the graphic & art industry. “The standard dictates that when viewing prints, a light source that replicates the D50 light source should be used”.

Thanks. There was rumour a while ago (I hope it is not cancelled in the meantime) that in the future Nichia will come with high power Optisolis leds, if true they may prove ideal for your purpose.

Should be ready for purchase this year:

Clemence will they be compatible with your boards? With your 36 emitter board, we can get like 20k ultra hi cri lumens? Love

My board? What for? With any COBs you can just plug and solder the lead. The idea of COB is you don’t need any MCPCB to mount the LED. Those tiny LEDs already internally pre-wired, soldered ready to use.

Many printings used Philips Master TL-D 90 Graphica 965 before led took the market. Do not know much about the norms,but D65 is also a standart I guess.

 I'm still using my HDS with stock Seoul SSC P4 for its very good CRI despite its poor lumens to size ratio. I mentioned its peculiar beam pattern "here":http://budgetlightforum.com/comment/1487803#comment-1487803. Once I got it, it stopped my flashlights quest for many years. I'm a bit puzzled by McGizmo's measurements about the CRI R12 = 66.1 because to my eyes it has deep and dense blue colors rendition, better than most CRI90 LEDs. -Blue colors look better than with a SST20 4000K to me.-

 

 

I used to own that light, it was my EDC for quite a few years. These days I use a Zebralight SC64c LE.
