I've checked on their light spectrum starting at 380 nm. Which means they have some UVa, but the energy radiated at the shortest wavelengths is not really much. What level of light intensity can you reach at the plant tops? Maybe I am totally wrong in believing that it's mainly UV that causes sunscald. My plants indoors get direct sunshine through the windows and the only problem is that glass does not let much UV in. That is on sunny days, which aren't numerous here. And they get scalded as a rule. Do you think CXB 3590s could solve my problem? That would be great, even though they are energy "guzzlers".
