Q: How long should I let my lighting systems(reflective and transmissive) warm up before I start using them for testing?
As a good rule of thumb, we recommend letting your lighting systems warm up for at least 20 minutes before testing.  This will give the lights enough time to achieve equilibrium and a color-stable condition.
