actinic lights
 
I just bought a light system with 4 T5 HOs. It has 2 actinic bulbs and 2 10000k daylight bulbs. the lights are wired in pairs. so I can turn on two at a time. So here are my questions

1
what is the purpose of the actinic light?? what does it do differently that the daylights?


2
should they be ran at the same time?

They are for coloration, they don't do anything. I don't even run them. With the right combination your corals show more color. That is what its used for, nothing else. If you run a good white light, you can run 4 white lights and keep higher lighting needs corals, and skip the actinics. I like 14k myself.
Most that have them run them one hour before white light and an hour after white light out, then moonlighting.

Is this what you purchased? I am considering this for my 40 breeder. Interesting suggestion on the 14k lights though, ReefingMadness. I'll look into those bulbs myself.
