I doubt that anyone reading this wants an aquarium to look like it has incandescent bulbs lighting it.

My first tank, back in the 1950's had an incandescent light, which I quickly replaced with a DIY T12 fluorescent light. I was amazed by how much better it looked with the fluorescent light, even though T12 bulbs, all that were available then, were notorious for making people look like ghouls.
