This item is standard 4ft T8 LED tube for plant growing. 240 red LED and 48 blue LED are included. It only emits light with wavelength which is helpful for plant growing. Therefore, 15W LED grow light tube can replace over 80W fluorescent tube or HPS lamp. Much less heat. It replaces T8 fluorescent tube directly. Please remove ballast when you install LED tube.
There are hundreds of choices of flowering bulbs that you can force into bloom indoors. These ones do not require any pre-chilling. Just plant them, water lightly, and count down the weeks until you have gorgeous blooms. If you've always wanted fragrant paperwhites or massive amaryllis blooms brightening up your winter days, be sure to order your blooms a few months ahead. Enjoy! #sponsored
