How often do I need to replace my bulbs?

We recommend that HPS bulbs should be replaced at least every 12 months (8 months or less is ideal).

MH bulbs should be replaced every 9 months (6 months or less is ideal) for maximum efficiency. The use of a light meter would be the best and most accurate way in which to measure your bulbs output as well as to help with bulb replacement timing.
