for me it went from buying individual Cree LED on those 20mm PCB boards and 60degree lens, coming up with a pattern spread, wiring up my own driver and programing a lighting schedule, to 100W multi LED chips, to going away from the DIY look and just buying LED fixture with a remote to program the lights to finally app based wifi controllers.DAILY QUESTION: How has reef lighting technology evolved since you first started reefing?
