Anyone know the productive life of a 315 CHM bulb? Someone told me to replace every year. Also where can I get best price? TIA

Brand will make a slight difference, but here is some info below that I found with a quick search;
Ceramic arc tubes are more resistant to breakdown, so they last a lot longer than MH and HPS bulbs. In fact, CMH grow lights tend to last over 24,000 hours while keeping at least 80% of their original intensity at the 20,000-hour mark. This overshadows the common 10,000-hour replacement rule for HPS & MH bulbs.
