MH bulb question

[mopar9012]

I find all these MH fixtures that would fit my tank perfectly...problem is they are all 250 Watts and thats over kill. Can you put a 150 Watt MH bulb in? or will it blow or something?

No. The ballast wattage and the bulb wattage must be the same.

use bulbs with poor par. you'll still have the heat of a 250w bulb but you wont cook the corals. thats one of the advantages of going 250 vs 175 or 150. you can get away with 20k or lower par 12-15k in situations that would require a great performing 150 or 175w bulb. not the most efficient way to go about it but if you have to have it thats what I'd do (or just replace the ballast if your up to it).
