yeah SE bulbs last like the and i heard DE bulbs need to be replaced a lil sooner like 6-8 months??

My last de bulbs lasted 12 months before I replaced them. Stuff was still growing like mad. They were 10k. I'm sure the ballast and bulb brands you have play a part in the equation.
Probably should have replaced them sooner like you said.

Some upto 18 months. I always change at the 1 year mark.

i just heard that DE bulbs burn harder and faster than SE bulbs so there for they need to be replaced more often but hey u never know i might have been told that so someone could make more money lol

If I had the money I'd replace mine every 8 months like you said Heck, I still have my old bulbs stored away in case one of my newer ones blows out unexpectadly. I'm so cheap lol!

well do they look like regular light bulbs that screw in?? then those are SE single ended bulbs since they screw in at one end
DE are small and slide into a receptical that has to contacts at each side of the bulb
