The OSRAM Sylvania HPL 115v (Extended or Long Life) model lamp is used in all of the ETC Source Four fixture line; Source 4 Par, Source 4 Zoom, Source 4 ParNEL, and Source 4 ERS. It can also be used in the Altman Phoenix. The 115v versions are most common due to the voltage loss through dimmers and cable runs drop the voltage current at the circuit into this range. The extended life version is great
for churches, high schools, and any other venue where it's difficult to get to lamps to maintenance them.
**If you are using the HPL lamp in a fixture that is being plugged directly into the wall, you may wish to look into the 120v version
available from our site.**
The HPL, or High Performance Lamp was developed as a way of producing the same amount of light from a lower wattage lamp. It's success comes from the fact that its compact filament design focuses all of the light from the most efficient location in a reflector. As a result, a 575 watt HPL lamp can provide the same output as the previous 1000 watt lamps for Ellipsoidal Reflectors. The HPL was proprietary and designed for the Source Four fixture from Electronic Theatre Controls (or ETC for short). Who can be found at etcconnect.com
This lamp uses 4 filaments, which is where the product line found it's name; Source 4. CHEAP COPYCATS:
