This is a way for me to make money if you order this light. I replaced all my old lights because they had shifted and nothing was growing. These lights are fantastic, but you need at least two or three per shelf. They are strong at 18 inches, and work up to 24 inches with a 45 deg spread. No fans, which is fantastic.
