30 watt 47” Far Red LED bar. The 730nm Far Red Lightbar is designed for plant canopy lighting and provides additional red energy outside of normal PAR (400–700nm). The Far Red Lightbar covers you to a 5’ x 12” area with very even intensity at 30” above canopy. The unit fits neatly within our FGI Uniformity Pro 640 LED grow light. We recommend 2 units per 4x4 grow space. Each Lightbar is prewired with an 8’ cord and 110v plug and are stand alone. Separate timer/switches are recommended to control the light interval. Far Red light is believed to create a competitive response in plants. This response generates faster growth rates and larger flowers.
