I'm trying to find out if anyone has had any experience with the Metrolux Light Integrator/Timer. I called Redlight (makers of Metrolux) and found that the spectrum for their sensor is quite broad...from approx. 3200K to 7000K?? if memory serves. I'm looking to expose in sunlight (UV) around 52-55K, and was wondering if there might be a UV filter out there that would make the Metrolux sensor more applicable to the UV range. I will also be using the "timer" for a metal-halide lamp when contact printing my PT/PL prints indoors.

Is there any other sensor anyone has had experience with that might be more applicable? Is the Metrolux worth $345? Any other approaches to exposing PT/PL prints that make the exposure repeatable under any conditions?

Thanks!
