bulb life

[borderreef]

Anyone know the life of the coralvue 175 watt 14k mh bulbs?

If they are lit for an average 10 to 12 hours a day, the normal bulb life is 12 months. It is reccommend to change 1 bulb every 6 months so you dont shock your tank with al new bulbs and more lighting strength all at once.

12 months, like most other lamps. I switched to all cv lamps in my tank, and am about due to start replacing them too. They have been great, best i've found for the price, and i've used alot of different lamps.
