High pressure sodium lights | Information by Electrical …
Today I was sent to find out why 6 - 150W high pressure sodium outdoor fixtures were not comming on at night. The 6 lights are controlled by a photo cell. When I found that the light with the photo cell mounted on it didnt have any power I went to the breaker that fed the 120V/20A circuit that fed the lights.
Replacing LU70 High Pressure Sodium Bulb with LED?
Your HPS (High Pressure Sodium) lamp has a ballast made of a hefty transformer, capacitor and "ignitor circuit". The transformer limits current (at a variety of voltages, settling at 55V) and the ignitor spikes a 3000 volt pulse onto the HPS bulb to …
