This has no ballasts to burn out like other plant light is new and never used. It is a LED light bulb with a long lifespan. Extreme energy efficiency permits this new LED panel to pay for itself many times over each year in electricity savings. No IR or UV light radiation. With this you can do the plants in the greenhouse or laboratory, and can completely replace the natural light, to promote plant growth. It is ideal for plant growth, flowering, fruiting.
