GrowPros Solutions HM480 480 Watt 3ft by 4ft LED Grow Light

The GrowPros Solutions HM480 LED Grow Light is a powerful and energy-efficient horticultural lighting system designed for indoor grow tents, hydroponic cultivation, and commercial grow facilities. Built to deliver strong illumination across a 3 ft × 4 ft flowering canopy, this 480-watt full-spectrum LED fixture provides balanced light output that supports plants through every stage of growth—from vegetative development to flowering.

Engineered with an optimized full-spectrum LED configuration, the HM480 closely mimics natural sunlight to maximize photosynthesis and plant health. The balanced spectrum promotes vigorous vegetative growth, improved flower formation, and higher overall yields while maintaining energy efficiency compared with traditional HID lighting systems.

The fixture produces approximately 1300 µmol/s of PPF with an efficiency of around 2.7 µmol/J, delivering strong light intensity and consistent canopy penetration. This performance allows the HM480 to outperform many larger traditional grow lights while using significantly less electricity, making it a practical choice for both professional cultivators and home growers.

Designed for flexibility and control, the HM480 supports 0–10V dimming and wireless control options, enabling growers to adjust light intensity according to plant growth stages. Its passive cooling system ensures quiet operation while maintaining stable temperatures for long-term reliability.

With a coverage area of 3 ft × 4 ft for flowering and up to 4 ft × 4 ft for vegetative growth, the HM480 provides even light distribution across the canopy. The durable design and efficient thermal management make it suitable for continuous operation in demanding indoor cultivation environments.
