The new GSE electronic ballast can manage all kind of MH metal highlight and HPS high pressure sodium bulbs at 250-400-600W. A UV- acid and waterproof foil with built in LED indicate the status and you can change the wattage in steps from power 660W-600W-400W-250W or with push and hold even in step less than 660W to 250W. GSE uses only finest high quality components such as aluminium cast and high temperature electrolytic capacitor, transistors Philips-NXP, high frequency ISKRA components etc... and source >84% EU manufactured components. An extremely big-surface aluminium radiator keeps the running temperature low and provides a long life of the components. The high frequency above 80kHz to 220kHz avoids acustic resonance of the bulb.
The ballast comes as a finished assembled product with 3m connector cable and 4m lamp cable to connect to the reflector E40. It is all waterproof sealed and has IP64 protection class.
