New never been used. Has 3 different plugs that can be plugged into timers for full control of sun and moon phases. One bulb is 10,000 k 65 watts. Other bulb is Actinic 65 watts. Also 2 Led blue bulbs. All have there own plug and switch. I bought this as a back up to the pair i had on a 100 gallon bow front corner tank but the pair of old coralife lights i had never broke. We enjoyed looking at our fish with the blue light on and all other lights off it is the moons light.
