I have a couple Solux 4700K I’ve used for color correcting prints. Tailored Lighting used to offer them in a desktop and clamp fixture, but not seeing them on the current web page. The task lamp had a weak joint and so that bulb was available for me to play with. There is a frosted glass convex diffuser to spread the beam a bit. I have it in a box with the diffusion plex about 10" above the convex diffuser which gives an even area for 35mm and maybe medium format. I’d like to get more so I fixed a piece of Dura-Lar half way between convex diffuser and diffusion plex above, but didn’t gain much if any even area. I suppose the solution is a deeper box.
BTW Nate if you’re reading I’m loving NegLabPro, really good stuff. Still testing and setting up but already loving this software.
