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

AB Lighting Waterproof Design


The AB Series LED Grow Lights are designed to a certified waterproof level of IP65. This waterproofing keeps the fixture in stable operating condition even in high humid environments. 

IP65 translates to International Protection -aka- Ingress Protection (IP) against Total Dust Ingress (level 6) and Low Pressure Water Jets from any Direction (level 5).

Light output levels for the AB Series can be manually adjusted via the knob control on the top of the fixture. Adjust light levels to 40%, 55%, 70%, 85%, or 100% depending on your plants’ needs.

If your grow requires a higher quantity of grow lights where manual adjustment would be impractical, AB Series Grow Lights can also be daisy-chained in quantities of up to 100 when paired with one of AB Lighting’s Smart Controllers.
