You will probably have to replace the bulbs for that system. One of the places that carries the full line of Odyssea lighting is Aquatraders.com. Many people prefer the Metal Halide Systems from Aquatraders since you will get significantly more wattage at the same price.
Here is a link to a 328W system with 1x Odyssea 250W DE HQI Bulb 15000K, 2x Odyssea 39W T5 High Output Bulb Actinic Blue, 2x Dual Bluemoon LED, and 4 power cords (HQI, LED, T5, and fan).

If I was looking on the cheep for a system I would probably go with this one instead of the 4 Bulb T5 I purchased.
