*The plant light for indoor growing is made of aerospace aluminum, which improves heat dissipation efficiency and makes it more sturdy than ordinary plant bulbs. Meanwhile the 20W 4000K Full Spectrum Grow Light has a CRI of 98+ to make plants look more vibrant. * It provides indoor plants with a full spectrum of 380-780nm (including red/blue light spectrum), which is close to sunlight and perfect for all stages of plant growth such as seed, vegetative, blooming and output. Compared with normal floor lamps, the black industrial grow light stand can also be used as your indoor decorative light, which protects your eyes better. *The indoor plant grow light comes with a 4/8/12H cycle timer system. 4/8/12H on, 20/16/12H off. This means that you only need to set the time once, and the plant grow light with stand will automatically cycle on and off every day, so you don't have to worry about the lighting when you are away from home. *The head rotates 360° and has 6 levels of height adjustment from 16.5-75 inches to accommodate tall plants, small plants, seedlings, and flowering.
