Been a long time sence we had a lighting fact thread

You always hear so many diffrent opinions.
"Iwasaki best growth......10k good color"

I do like the color of my Iwasaki's with 4 t8 actinics OD 2X.
but I do like the color of 10k bulbs as well.

I suppose another example of a great 10k lit tank is MTDEW man's on RC.
2 10k bulbs, one single ended and one double ended and awsome growth and color on his tank.

How often do you replace your bulbs?
