So I would love to start a discussion on how long we should run our bulbs before replacing them.

I know the standard answer is 12 months....but why?

Spectrum shift? The sun kelven I believe is 5100k. So you are trying to tell me we are shifting that much? Negative... The ocean seems to do just fine with a spectrum that low.

Dimmer? Even if I lost 30% which is a huge shift I would still grow corals like crazy with my ATI. So negative on that one as well.

So with that said does anyone have any links with actual real testing on t5 bulb's life expectancy?

Maybe I just going at this all the wrong way but I'm starting to get the feeling we are replacing our bulbs to early.

I'm sorry I can't offer any links to studies but I change mine past the one year mark.

That's what the norm is. But Ive yet to see real facts. I'm sure I'm just being dumb here but it's got me thinking.

I believe the ones I am running now are about 18 months. I don't see any problems. I believe if one buys a good quality bulb they should get more than 6months out of it.

I don't have a link but obviously people have done tests with PAR meters and corals need a specific range
