Designed to ensure reliable operation of 70 Watt TS-R CDM, CDO, MH, SON and HPI lamps this HID-Basic semi-parallel copper ballast from Philips Lighting is ideal for functional outdoor and horticultural lighting applications. This impregnated, electromagnetic ballast offers improved thermal management features, resulting in a cooler ballast and comes equipped with screw terminal blocks for ease of installation. Featuring End of Lamp Life protection as standard it also boasts minimal watt loss. This ballast requires an external semi-parallel ignitor (not for SON-I lamps).
