But most of that is 130w of actinic, which isn't as useful to corals for growth as more 10000k would be. Actinics do provide some but not nearly as much useful light spectrum as more white light would & its more for our "viewing pleasure". When I switched out my 50/50s for straight 10000k bulbs, it made a huge difference in growth.
