Introducing The FOHSE LED Grow Light - A3i 1500W - Samsung Diodes - IP67

The Fohse A3i model is an industrial LED light designed for high-bay, single-level grow environments.

It is built to withstand harsh conditions, such as exposure to pests and submersion in water, and uses diodes from leading manufacturers.

It has swiveling light bars for maximum canopy penetration and can provide up to 12 years of light.

It is also highly efficient in terms of heat management, producing 60% more light per BTU than HPS systems and has high photosynthetic photon efficiency levels due to its abundance of diodes.

It also has a low surface temperature and three layers of protection against electrical overload.

Made with diodes from industry-leading diode manufacturers, the A3i is Fohse’s answer to the low output and poor canopy penetration of the growing industry’s early-generation LED systems, with swivelling light bars to achieve maximum canopy penetration via cross illumination to neighbouring grow plots.

Models of the A3i provide between 50,000 and 110,000 hours of light up to 12 years’ worth.

The system is safety-conscious as well, with an average surface temperature of 115 degrees Fahrenheit approximately the temperature of a sink full of dishwater at full heat and three layers of protection against electrical overload scenarios.

Detailed Specifications

Wattage and Power

• Wattage at Full Power = 150ul cull l0 (+/-30 watts due to common variability in driver consumption. This is measured at the plug and NOT at the internal power supply like some manufactures claim. This means that 1500 watts is actually what is pulled from the outlet) 
• Voltage Options - Low Voltage Model accepts 100v up to 277v & High Voltage option accepts 250v up to 480v
• Amperage at Full Power (Amps = Watts * Volts) 12.5A @ 120V; 7.2A @ 208V; 6.25A @ 240V; 5.41A @ 277; 4.32A @ 347V; 3.1A @ 480
• Amperage at Full Power (Amps = Watts * Volts) - 12.5A @ 120V; 7.2A @ 208V; 6.25A @ 240V; 5.41A @ 277; 4.32A @ 347V; 3.1A @ 480V
