PHOTOBIO•IU - Single Fixture

120W Linear LED Grow Light for Intercanopy, Undercanopy, and Toplight Uses

The PHOTOBIO•IU is a grow light with infinite possibilities. The 4-ft linear light bar with a 150-degree beam angle is a new power play as undercanopy lighting for boosting your light penetration. It hangs vertically as interlighting for your vine crops such as tomatoes or cucumbers. With the side entry of its cable management and the classic best-selling S4 spectrum, PHOTOBIO•IU is a powerful yet simple toplight for greenhouse and indoor growing.

For growers looking for the next frontier of side lighting, angled lighting, or cage lighting, the PHOTOBIO•IU lineup includes a 180-degree tilting tripod stand (sold separately). For growers wanting a versatile light bar to integrate into their next grow system, PHOTOBIO•IU's interconnectivity allows you to daisy chain up to 18 fixtures (actual number may vary depending on wire gauge and input voltages).
