The long life of the Source Four HID PAR and PARNel lamps ensures they run for 12,000 hours - in comparison with the incandescent lamp of approximately 300 hours and the tungsten halogen lamp life of 2,000 hours. This means low maintenance - ideal for locations that can’t be reached often or easily. Source Four HID gives the level of performance of a 2,000 hour 575W Source Four luminaire, but with 10,000 additional hours. The metal halide Source Four PAR and PARNel HID offer clean washes of light in four beam spreads and the HID PARNel boasts a 25°-45° degree beam angle.
Using a 150W electronic ballast with a power factor of greater than 95% compared to some competitive units’ ballasts at less than 70%, the Source Four HID PAR and PARNel ballast have an overall efficiency of greater than 90%. With their 1.5 amps operating current and harmonic distortion of less than 10%, it’s possible to safely place more Source Four HIDs on a 20A circuit than other manufacturers’ units which operate at 2.3 amps.
The HID PAR and PARNel now complete ETC’s family of Source Four HID luminaires for architectural applications. All fixtures are available in black, white and silver grey as standard, while any custom colour can be made to meet customer specification (with the exception of the Source Four Zooms, available in black only).
There are now five fixtures in the family: Source Four HID Fixed Focus, Source Four HID junior, Source Four HID Zoom (two zoom ranges: 15°-30° and 25°-50°), Source Four HID PAR and Source Four HID PARNel.
