That is a big disadvantage compared to HPS bulbs which can go closer to 18-24 months. After one year of continuous use the MH bulb will be shinning at only 60-70 percent of original so, you are paying for 1000 watts and only getting about 700. You may not have noticed it by eye because of course this happens over time.

AugustWest,

What are the temps in the grow room? I see the margins starting to fold over indicating heat stress.

I have a light meter and its at 89% from what it was...

Big difference between me and other using these lights is my room is Airconditioned and cool a/c air is being blown in on one end and sucked out the other (the hood) so they are not running as hot as someone with just in out fans.

but yes i know, and i consider myself very very lucky so far
