Active Grow Launches UL Listed LoPro Max Horticultural Luminaires for Commercial and Home Growers

Active Grow, the sustainable horticultural lighting manufacturer, is proud to announce the launch of its LoPro Max 640W and 320W horticultural luminaires. These lightweight, UL Listed fixtures conveniently replace 600-1000 W and 400-600 W HPS lights in vertical racking or sea of green commercial applications, using nearly half the energy and producing half the heat. The concealed-driver design means no messy cabling or bulky external drivers. The ultra-thin profile (just 2.47") allows the luminaires to go to work in spaces with minimal vertical clearance. Integrated dimming and a tool-less installation make these fixtures perfect options for home growers with tents or hydroponic benches.

Each luminaire comes standard with the Active Grow Entourage Spectrum which is optimized to boost growth during both vegetative and flowering cycles by incorporating additional Far-Red 730 nm wavelengths. These Far-Red wavelengths combine with 660-680 nm wavelengths to increase plant photosynthesis rates via the Emerson effect which results in faster grow cycles, enhanced flavonoid content and a higher percentage of trichomes in cannabis. The natural high CRI 94 light also makes plants look more vivid, making inspection and maintenance of plants easier.

The LoPro Max luminaires utilize Philips chipsets for maximum light output and proprietary optics that create uniform light coverage and deep canopy penetration for high DLI requirement plants. The slim form factor and 4-8 bar design allows the fixtures to be placed safely above plants in low height applications without burning the canopy. The 640 W and 320 W luminaires feature typical PBAR (280-800 nm) outputs of 1644 µmol/s and 822 µmol/s respectively, giving each an exceptional efficacy of 2.6 µmol/J. The built-in 0-10V rotary dimmer lets growers adjust the light output from 10-100% without the need for additional wiring or installation.

Active Grow builds each fixture using IP65 rated components to withstand the rigors of tough CEA environments. The proprietary SafeShield optic creates a thermal buffer to protect the LED diodes from overheating, guaranteeing a 50,000-hour lifetime. Both versions use premium universal voltage drivers, can be daisy chained on 120 V, 240 V and 277 V circuits and come with a 5-year warranty. For larger installations, the luminaires can be used with wireless grouping control systems (up to 100 fixtures).
