The LGM Chrome series of LED plant lighting is both powerful and efficient. The unique, patent pending lens is designed to increase both penetration and PAR output. These Hybrid Compound Lens Inspired by the lenses used in lighthouses around the world to maximize the power and penetration of lights. The Chrome led grow light system includes characteristics of a 30, 60, 70, 90, and 120 degree lens. Just as a prism bends light in different ways, the Chrome lens was developed to optimize PAR at various distances. They are designed to make sure that your plants are getting a perfect mixture of all wave lengths. With a cooling fan to maximize airflow throughout the grow light, the LGM Chrome series grow tent led lights use a high axial-flow 120mm bearing fan with sealed bearings and a thin-profile fan cover for maximum air throughout.
