Depends on your setup but a lot of people here like those T5 lights. I was too lazy to figure out how to find ones that would suit my shelves, so I bought these cheap LED ones. They create some color stressing, and our more than enough for props, but they can't stop some of my older succulents from stretching. Especially echeverias.
