While our Pianta grow lights are designed to support plant growth, they can be used as ceiling lights as long as they are pointed directly towards your plants and positioned within 25cm - 90cm for optimal effectiveness. Our grow lights are most effective when used directly above your plants, focusing on wavelengths that promote growth.
