250W的，400W的，600W的，1000W电子压载

Efficient - Produces 27% more lumens than core-coil magnetic ballasts. - High energy saving - Produces 11% to 16% more lumens than standard electronic ballasts. - Small heat production - Provides full watts to bulb lightings. - Starts up fast as it reaches full brightness 20 times faster than magnetic ballasts. - Initial power surge to light up the ballast is NOT required. - Provides a broader light spectrum. - Improves lamp life up to 3.5 times. - Every Sunny digital E - ballast is burned for 15 hours at the factory for extreme testing before introducing to the market. - Our return rate is less than 0.85%. Intelligent Engineering - Intelligent microprocessors implemented to adjust the output when lamps are degrading. - Anti-burn system that performs cut-off circuitry for cooling and safety when the ballast reaches 60°C. - High-temperature resistance allows Ballasts to be mounted in areas with temperatures -10°C to 45°C - Ballasts are engineered for easy troubleshooting, identifying errors such as a short in the wiring or a malfunctioning lamp) and gracefully turning the system off, allowing the user to be informed for troubleshooting. - Safety protection such as built-in fuse protections, thermal overload protection, water resistance, and sleep mode function are implemented to emphasize Sunnys dedication to providing safe ballasts. Intelligent Architecture - Less than 10 lbs compared to magnetic ballasts which averages 41.2 lbs. - Output cord designed to be detachable for easy repositioning of other equipment without moving the ballast. - No fans thus no moving parts. No annoying sounds or vibrations. - Output cord is RF shielded which prohibits interference with radio and TV satellite signals. - Smart hanger for convenient hanging in greenhouse.
