GLB Series 315W CMH Electronic Ballast, DE/SE Compatible, 120-277VAC

The Growlite GLB Series 315W CMH Electronic Ballast is designed to deliver efficient and reliable operation for ceramic metal halide (CMH) horticultural lighting systems. Engineered to optimize lamp performance, this ballast provides stable output and high efficiency when paired with compatible 315W CMH lamps, helping reduce color shift, heat, and operational noise. The ballast supports both single-ended (SE) and double-ended (DE) 315W CMH lamps, offering flexibility across a wide range of horticultural lighting applications. Automatic voltage sensing allows operation on 120-277VAC input, simplifying installation and ensuring compatibility with various electrical systems. Designed for performance and longevity, the GLB Series incorporates a soft-start feature that stabilizes startup loads and extends lamp life. The ballast operates at low frequency with constant output, delivering consistent light levels while minimizing flicker and electrical stress on the lamp. An integrated LED status display provides real-time operating feedback, while a standard S-type lamp connector and included 6-foot power cord simplify installation. The compact design allows easy mounting within grow systems or alongside reflectors in commercial and indoor farming environments. Advanced protection features include safeguards against short circuit, open circuit, ignition failure, end-of-lamp-life conditions, overheating, and over/under voltage. These protections help ensure safe operation and long-term reliability in demanding grow environments. With high power factor (>/=0.95), low harmonic distortion (<20%), and durable construction, the Growlite GLB Series 315W CMH Electronic Ballast provides a dependable solution for powering CMH grow lighting systems in greenhouses, indoor farms, and controlled environment agriculture applications.
