The lighting is Coralife Aqualight - Deluxe Series-Double linear strip. I'm using a 48 inch and 24 inch unit. Both units have 2 each 65 watt true actinic 03 blue and 2 each 65 watt 10,000K daylight straight pin compact flourescent lamps. They also have independant switches so I can run the actinics and 10,00K's together or seperately. They have been trouble free since I set this system up.
