Been a long time sence we had a lighting fact thread

I have switch from 250 iwasaki to 400 radium on agro ballast 4 month ago and they are IMO the way to go for a show tank they have improve the color and still improve it each day at first I was tinking they were great but with time all the color shift from brown to solid puple,pink,blue....like crazy! The only coral that was looking more beautiful under the saki was a yellow plate so they are not great but amazing! for the grow I have not see any slower grow and I was with the saki for 2+ year the saki was only 6 month old when I have change for radium

I have try the m135 pulse start ballast and found it realy much more dim to my eye but no test have been done with PAR the color was looking similar but I could realy see shadow in the botom tank note that I have not try with a new bulb but only change the ballast on the old bulb. I have now turned back to the agro

I will keep people update for the bulb life but from now I have not see any noticable color shift or slower grow
