I have had a couple coralife bulbs blow after a few months use, how much worse can you get than that?
if you have the proof of purchase,
they might replace them for you.
my coralife bulbs are still going
strong after nearly a year of use.
my 8800k CustomSeaLife are also
burning fine after a year, but I can
understand how quality can vary
from bulb to bulb.
so the bottom line is to use a vendor or manufacturer
who will REPLACE bulbs if they are unreasonably faulty,
and you can't really do that with Chinese no name bulbs
on ebaY or some Yahoo virtual store web sight.
