I seem to recall we discussed calibration on here before and someone from
ETC chimed in that given the control conditions and quality/cost of sensor and test/measurement equipment required it wasn't
practical at this time to have customers field calibrate their own fixtures. Certainly subject to possible change in years to come, but I was looking at picking up a color spectrometer for my own entertainment and I've since backburnered that investment because it's about $1800.
In specific regards to
Selador, there's the also the matter that those are first gen
LED products by
ETC that date back about 10 years. I'm not sure how much difference there is in the brains of those fixtures from the very most original
Selador x7 fixtures before
ETC acquired the
line, but I'd say that the overall product R&D is about 16-17 years old, 10 years at best if there were updates made when
ETC acquired
Selador. When Rob Gerlach and Novella Smith were building these in Rob's garage, I have to imagine that end user field calibration was nowhere on the product development roadmap. At that
point I think they were more focused on seeing that they could even
build what they wanted to and then being able to find customers for it.
