I will try and get some good ones today. When I first installed them they were a nice blue shade. I unplugged the actinics and noticed no difference. On my reeflux I could definitely tell the difference. The blue actually intensified a little more the next day. So far no i'll effects on the sps. My actinics are only on for 3 hrs now. 1.5hrs before the halides come on and 1.5 before they come off.
