I have (5) 2' sections. Each 2' section has 67-72 led 3 watt cree "old school" DIY Reefledlights.com, non-dimmable. All run 100% if on, some have 70/80 degree lenses, some have no lense. In addition to this, I also have a couple/few additional home center clamp on led 120 watt equivalent spots 5k. I start 10-11am with all my blues. Then half white turn on around 11-noon. An hour later all turn on. At around 9-10 pm half whites turn off. An hour later all whites turn off, around midnight blue turn off. About 13 hours total, with 9 hours being full 100% on. Times are approx, timers get messed up when power goes out, sometimes I don't fix it for a while, old school timers too.
