GLB Series 1000W Electronic Ballast, DE/SE Compatible, 240/277VAC

The Growlite GLB Series Electronic Ballast is a high-performance horticultural lighting power supply designed to operate both single-ended (SE) and double-ended (DE) high-intensity discharge lamps. Engineered for commercial grow environments, the GLB Series delivers reliable, energy-efficient performance with flexible wattage control and advanced protection features. The ballast supports multiple dimming levels, including 600W, 750W, and 825W settings, along with a 1000W full-power mode and an optional 1150W overdrive setting. This flexibility allows growers to optimize light output based on plant growth stage, environmental conditions, and energy management strategies. Designed for versatility, the GLB Series operates on 240/277VAC input with automatic voltage sensing and includes a standard S-type lamp connector. External control capability via 0-10V input allows integration with lighting control systems for precise dimming and automation. The unit features a fanless design for quiet operation and improved reliability, along with a weathertight twist-lock power input connector and a 6-foot power cord for easy installation. A built-in LED display provides status indication and operational feedback for simplified monitoring and troubleshooting. Advanced protection features include safeguards against short circuit, open circuit, ignition failure, thermal overload, over-voltage, under-voltage, and end-of-lamp-life conditions. Soft-start and staggered ignition functions help extend lamp life and reduce electrical stress during startup. With high power factor (>/=0.97), low total harmonic distortion (<10%), and durable construction, the Growlite GLB Series Electronic Ballast provides a dependable solution for powering HID grow lighting systems in commercial greenhouses, indoor farms, and controlled environment agriculture applications.
