YOu have all heard different stuffy but ever since I started in SW
all I have read and heard was that PC
are the longest lastign bulb and MH
bulbs typically need to be replace sooner.
I have heard that PC
need replacment each year and that MH
last 6-8 months before replacment is needed. I am sure different bulbs and different setups will give different lifespans to the bulbs but I have never heard of a MH
lasting over a year.
Again none of us are bulb experts but liek I said the majority of information I have run across is that the MH
are great for reefs but they are more costly and need replacment more often than VHO
