Im looking for a good 2 bulb fixture that comes in 30 in. I've looked at Petsmart because it's local but every review i read says that on most fixtures you can only get around 3,500 hours on most of them, that just can't cut it for me, i dont want to be forking out $100 every year!
Your question doesn't make sense. Fixtures don't require replacement. A fixture is what the bulb fits into. What bulbs are you looking at ?
