The HLG 30 UVA Supplement by Horticulture Lighting Group is a high-performance LED light bar designed to introduce ultraviolet-A (UVA) wavelengths into your indoor grow environment. Spanning 24″ in length, it uses both 365 nm and 385 nm UVA diodes and is engineered for use on a 12-hour photoperiod in 4′ × 4′ to 5′ × 5′ grow spaces. This bar integrates a passive, fan-free aluminum chassis with a built-in power supply, ensuring silent operation and reliable thermal performance under humid conditions. It bolts directly onto compatible HLG fixtures using supplied hangers and screws; or it can be independently mounted alongside any other lighting system. But if you’re thinking about another more powerful or a different lighting system, then check out the HLG 650R or even the HLG Scorpion Diablo V2.
