Because we have so much sun/U/V here on the Gulf Coast I must admit that I only use the lights(I have a Delta and a Safelight unit) when the sun is low or cloudy or repairing in the shade etc.Most of the time works great.I only notice the change on a combo etc with multiple legs etc.I think you may be on to something................Any advise or thoughts??
