The GrowPros Solutions HM240 LED Grow Light is a compact and energy-efficient horticultural lighting system designed for indoor grow racks, hydroponic cultivation, and greenhouse environments. Engineered to deliver consistent illumination across a 2 ft × 4 ft grow area, this 240-watt full-spectrum LED fixture provides balanced lighting to support plants from seedling and vegetative stages through flowering.

Featuring an optimized full-spectrum LED configuration, the HM240 closely replicates natural sunlight to maximize photosynthesis and plant health. This balanced spectrum helps promote vigorous vegetative growth, strong plant structure, and improved flowering performance while maintaining lower energy consumption compared with traditional HID or HPS lighting systems.

The fixture produces approximately 624 µmol/s of PPF with an efficiency of about 2.6 µmol/J, delivering strong light output and consistent canopy penetration. This high performance allows growers to achieve excellent crop productivity while using significantly less power than conventional grow lighting solutions.

Designed for flexibility and professional cultivation setups, the HM240 includes an integrated dimmer adjustable from 25% to 110%, enabling growers to fine-tune light intensity for different plant growth stages. The system also supports 0–10V dimming and compatibility with grow controllers such as the TrolMaster Hydro-X system, allowing automated lighting management in commercial facilities.

The HM240 features a foldable, plug-and-play design that simplifies installation and transportation. Its passive cooling thermal management system ensures quiet operation and extended LED lifespan while maintaining stable performance. With a wide 120–277V input voltage, the light can easily integrate into both residential and commercial electrical systems.
