This it?
So still everyone finds these better than T5's?
Not just for color but for growth?
Im going to have over 7 clams all VERY large so i want good lighting.
yup those are the bulbs..i think there like the aqua blue t5s...from my exp. it takes two t5s to equal one of those vho's when it comes to pop or color....there power hogs but they perform...
