The AC Infinity IONBOARD S33 is a high-performance, full-spectrum LED grow light designed to enhance plant growth and maximize yields across all stages of cultivation. Utilizing advanced Samsung LM301H diodes, this 240W grow light offers powerful, efficient lighting optimized for germination, vegetative, and flowering phases. The diodes are algorithmically positioned to ensure the most uniform PAR map and deep canopy penetration, providing your plants with consistent and effective light coverage.
Built on a robust, fanless unibody aluminum board, the IONBOARD S33 is designed for durability and longevity. Its IP-65 rating ensures peak performance even in environments with high humidity and heat, making it suitable for a variety of grow tents and spaces. The light fixture includes a pair of metal bar hangers and rope hangers, making installation easy and secure.
The proprietary driver of the IONBOARD S33 allows for precise light intensity control with a dimmer that adjusts from 0 to 100% in 20% increments. This driver also supports daisy chaining and connectivity with AC Infinity's smart controllers, enabling advanced features such as grow cycle scheduling, app control, and integration with other grow equipment. This seamless integration within the UIS™ platform ensures you can create and maintain the optimal environment for your plants.
Key specifications include a coverage area of 3x3 ft., an efficiency of 2.7 µmol/J, and a PPFD of 1702. The light spectrum encompasses 660nm, 730nm, 3000K, and 5000K, providing a balanced range suitable for various plant stages. With a life expectancy of 50,000 hours, the IONBOARD S33 is a reliable choice for any grower seeking to enhance their plant cultivation with cutting-edge LED technology.
