Hi there,

Does the Refugium and ATS lighting have to be purple or is it about lumen, kelvin, watt and nm numbers?

Regards Duzzy
 
I’ve run refugiums a in the past with old standard fluorescent grow lights. I think those were in the 6500k range. So, no they don’t HAVE to be purple/red.
 
Always worked for me. HD and Lowes sell a 6500 LED flood lamp I use on mine.
