This sale is for only 3 months old Metal Halide Ballast by Lumatek LK 400. I bought this ballast brand new and I have switched to Led\'s on my reef tank and I am selling these ballasts. This ballast can run multiple wattage bulbs (250, 275, 400 and super lumens. Anytime you need to change the bulb to higher wattage, You don\'t need to buy new ballast, Just switch to high wattage via dial and you are good to go, It come with special pump that gets connected to MH reflector. As per my understanding, This can run doubble ended and single ended metal halide bulbs. Please send message if you have any question.
Thank you for looking,
