About this item Upgraded Four Heads Plant Grow Light - We designed this Newest Grow Light with four goose necks not only solved the trouble of setup and inflexibility of traditional hanging grow light but also provides a much wider coverage area than clip grow light with two or three arms. The coverage area with one head is roughly 24-27 inches depending on the height you have the head aimed. Natural Sun Light Required by Plants - Based on the type and output of light (PAR) needed to support photosynthesis, we manufactured this LED Grow Lights with 3 color modes(Red Light, Blue Light & Mixed Light) and 9 brightness settings ranging from 20% to 100%, which effectively supplemented the lack of natural sunlight and promoted the growth of plants at all stages. Intelligent Timing Function & High Quality LED Circuits - This grow light with the circular-memory time function allows to automatically turn on/off every day according to your settings, which requires no manual operation and takes good care of your plants when you are on work or a vacation. The LED Bulbs made of aviation aluminum heat conductive material greatly extended the longevity more than 50,000 hours and provides steady current without flickering, melting or burning. 360-Degree Adjustable Goose Necks & Easy to Use - Powered by USB or AC Power Plug(USB power adapter included ), itҳ portable and convenient to use at home or in the office. The goose necks can be rotated 360 degrees so you can control the angle easily and the distance between the lamp and plants. This grow light applies to indoor potted plants, leaf cuttings, greenhouse vegetables etc. We stand behind our Product Quality!
