With the ETC 25 to 50˚ Source Four 70 W Ellipsoidal Zoom HID with Edison Connector (White), you can draw attention to your interior design and architectural details, call out specific objects and dramatize display spaces, or project interest-grabbing patterns, logos and signage. This Source Four HID’s long-life 12,000-hour lamp allows for low maintenance and less lamp change-out, which is perfect for positions that can’t be reached often or easily—like tall museum ceilings or vaulted church areas.
This HID lamp gives you the level of performance of a 2,000-hour Source Four fixture but with 10,000 additional hours. The metal-halide fixture has features that include a cool beam, imaging, pattern projection, and a bright, even field. It uses an electronic ballast with a power factor greater than 95%, and has an efficiency of greater than 90%. With its 1.5 amps operating current, you can safely place more Source Four HIDs on a 20 A circuit. Plus, this non-dimmable fixture is UL Listed for damp locations.
