I’m using maxisun pb2000 ( 3 of them ) in a 4×4 tent, first grow with them but plants love em, on sale they are $230 per on amazon. I added ir ( they have near ir diodes ) with $10. Ir diodes for .50c each and an arduino nano ( $3 ) with a light sensor ( $1) wrote a basic program, light sensor senses lights on and turns ir on.. light company’s rape people for single ir diodes in their lights imo. 🙂
