[QUOTE=Gregcoyote;1310503]Different bulbs age differently. The spectrum shifts, usually to the red part of the spectrum, the part corals could care less about. It is why I love LED
lighting, they stay relatively flat until they burn out. Unfortunately, your eye cannot see this slow shift, but your corals can. The only solution is a regular bulb change and that's hard to make yourself do because the bulb visually looks fine.
....so how does one actually know when it's time to change out your bulbs??? And for someone like me who knows nothing about 'em ,what do I look for??
There seems to be so many choices,..right now as I said in the original post I have two blue bulbs a sun bulb and a 454 bulb running,..all which means nothing to me,..is this a good setup or should I look to buy something else the next time? My bulbs are currently only two months old
