So I'm thinking about the goose neck solux.
If that works for you. I'ld recommend you get it. It's the most accurate to the color rendering characteristics of a sunbeam on the planet.
There's an observation I'ld like to relate here about daylight balanced LED's I'm starting to notice in how they circumvent the green to bluegreen spike in their spectra. And I see it in the photo posted by Garnick's studio setup and in my Hyperikon LED bulbs.
Couple of years ago I bought a 27" LG LED sRGB gamut display that was color calibrated at the factory by a very expensive Minolta Color Analyzer. What I've found in the ensuing years comparing its native white to the high CRI LED 4000K- 5000K bulbs is that the bulb's color of white has a magenta filtering component that attempts to neutralize their green spike. Since it is very difficult for us humans to see the exact color of bright transmissive white on a display it works out pretty well but not as perfect as the Solux.
I just found this out when calibrating/profiling my LED display with the Colormunki Display set to target white balance of D65 which now makes my native white and neutral grays look greenish. I checked the Target D65 profile's vcgt tag (I have a Mac) which shows the red and blue curves equally pulled way down from the top that are making my video card render in a way my supposedly native 6500K white point of my display comply with Xrite's definition of 6500K which is attempting to override the magenta bias of white I can't see on my display.
This could be an alternate method of double profiling due to the appearance of the color of white can be subject to adaptation and thus my native display white, though it was measured at the factory to be 6500K, by setting to target D65 (instead of native) tells the software that the Minolta Color Analyzer definition of 6500K isn't so perfectly neutral.
Not sure but when I see a pattern of manipulation of color with daylight LED bulbs compared to LED backlit displays, it makes me take note. Any PAR30 or PAR20 bulb as on the Lumicrest site will work but find out how much light they put out first because you may need to buy more than one to get it to match the luminance of your bright white LED display which is far more influential in color matching prints.
I'm not that concerned about it because my eyes adapt pretty well to slight variances of white light and any tint that might exist in neutral grays. It's so subtle that it doesn't really drastically change the appearance of memory colors but B&W prints might be slightly off from the display under these LED bulbs.
Just something I discovered about LED daylight bulbs.
