Hey guys, I run my 6500k T8 bulbs 18 hours per day from February 1st to late May/early June. That's roughly 2160 hours per season and I have 2 seasons on them, so about 4320 hours so far. This year will be the 3rd season on them. They're still bright, but noticeably not as bright as new bulbs are. Should I replace them for optimal growing results?
I've read that fluorescent bulbs degrade not only in total light output, but spectrum can also change a bit as time goes on and they wear out.
Opinions?
Thanks,
T.
