Our 23.6-inch(60cm) UV & IR light bar set consists of 4 bars, each UV light bar equipped with a durable and sturdy metal casing and 60 diodes, while each IR light bar equipped with a durable and sturdy metal casing and 44 diodes.
Why use 730nm IR supplemental light bar? Stem Boost, Flower Induction, Light-induced Sleep
