What a grow light means here
On this site, a grow light means an electric light made to light plants indoors. Makers describe their lights by type, such as LED, and list wattage and coverage on the label.
A light over a wet system
A grow light is an electrical fixture that may hang or stand over water. Follow the maker's instructions for mounting, height, and distance from water. Keep plugs, cords, and connections away from water, and follow every maker's instructions.
GFCIs
CPSC says a GFCI "is designed to protect people from severe or fatal electric shocks," and that ground fault protection is used "especially for circuit outlets in particularly vulnerable areas such as where electrical equipment is near water." Use a qualified electrician for any wiring.
Hours of light
We do not give light hours or schedules. Follow the maker's instructions for the light and any timer you use with it.
Words on the box
Words on a light's box, such as full spectrum, are the maker's terms. We do not check them or compare lights.
What we do not say
We do not say what any light will do for a plant. Results vary.
