AB Lighting’s special structure heat dissipation design keeps the fixture body cool to the touch. It allows the light to work at a much lower temperature compared to traditional HPS/HID grow lights. This unique design not only extends the lifespan of the grow light, but also benefits the grow environment by releasing heat into the room at a much slower rate allowing for more efficient atmospheric turnover.

Slower Heat Release = Better Grow Atmosphere


TL840 Heat Sink


TL840 Waterproofing


The TL840 Grow Light is designed to a certified waterproof level of IP66. This waterproofing keeps the fixture in stable operating condition even during grow room pressure washing days. 

IP66 translates to International Protection -aka- Ingress Protection (IP) against Total Dust Ingress (level 6) and High Pressure Water Jets from any Direction (level 6).
