    10k bulbs last 12-16mos, 14-20K is more like 6-8mos, and actinics are about the same as the 14-20Ks....IME the bluer the bulb, the shorter its lifespan.

    Changing bulbs

    Just wondered how often you guys recommend changing the MH bulbs and Actinic bulbs?

    Try the Phoenix 14k, I have some of these in my aquaspacelight and they are quite blue. ypu loose alot of brightness compared to the 10k, but the color is so much better.

    Hi Ryan, check out the new Iwaski -150W-14K-SE. They're reported to have more PAR than other brands's 250W'ers. I believe Premium Aquatics has them, Bob
