$2? Where do you shop? I can't get those prices at Home Depot. The
normal tube are about $6 a piece I think. As for normal light, my
understanding is that it contains spectrum between red and blue. It
makes the light look brighter but encourages algae growth. Well, at
least that was what I read. The chart of that Zoo-med Flora Sun tube
showed two humps one at red and one at blue. To my eyes, the light
looked dim and unappealing, but my plants seem to like it.

Maybe it was a sale or something but there were $1.99 cool white
and warm white tubes at Home Depot around xmas.

Green makes tubes look brighter, not red or blue. But plants
can more easily utilize red and blue.
