True, not a nice site for searching but this is the shortest route to the lamp measurements, tap again on the lamp measurements at the top right for further searches, do not try the backward routes:http://www.olino.org/us/ov/lamps
Enough measurements there; the CRI measurement has a target included and a percentage is shown per patch. There is a link to comments on CRI in general so it all becomes relative. There are plots of the spectral distribution + the fall off to lower color temperatures at the widest angle edge. There is the S/P ratio number with the plots for rods and cones sensivity shift for that lamp if you really want that studio to be below 50 lumen on the walls. I would count in the Kruithof curve, the lower the ambient light to the monitor illumination the warmer the ambient light can be in my opinion. With 6500K on your monitor and near 140 cd/m2 I would not go too low with the studio lighting and keep it at 4000-5000K at most, you will not find nice lamps that match 6500K and have good CRI anyway, LEDs below 4000K can have quite good CRI numbers for your purpose. Wear a grey shirt or black and white striped one and make sure no reflections are on the monitor. In your case no viewing light nearby helps then. The Olino lamp measurements have all the other things like efficiency, PAR, etc etc that may be of less interest to you. Get one Solux lamp for a viewing light for the few times you have to check prints.
I have 105-110 CD/M2, 5000K on the NEC 2690, CFL lamp of 5000K or Osram 4500K Cool Blue 51 halogens (measured 4100K though but Solux like technology) for viewing lights (+ odd ones for other display conditions), hardly any ambient light but some 3000K halogens 20 watts at the end of the studio, some daylight coming in at the same side. The printers are in the other space with Philips 950s at the ceiling. Larger Just Norm viewing light there with fluorescents. I want to replace the ambient light halogens with good GU 5.3 12 volt LEDS of 4000K but see no good ones yet. I am a printer so it is harder to get it right. Waiting for the quantum dot LEDS with this technology:http://news.vanderbilt.edu/2012/05/quantum-dots/
You have to check yourself but this LED strip should be good for 3000K in my opinion:http://www.olino.org/us/articles/2013/04/21/proled-finland-ledstrip-ledvalonauha-8-3wm-high-cri
At the same color temperature but Edison socket:http://www.olino.org/us/articles/2012/10/21/philips-dimmable-led-light-bulb-with-e27-fitting
Or 4000K tube 150cm:http://www.olino.org/us/articles/2012/12/19/lemnis-lighting-asia-led-tube-light-150-cm-glass-cover
There are more + some 4000-5000K LEDs too in ceiling fixtures but the Red patch drops considerably in color fidelity.
