What is the difference between Solarc and HID lamps?
HID is the acronym for High Intensity Discharge. It refers essentially to any arc (filamentless) lamp with high intensity. There are many types of HID lamps. Most highway and parking lot lamps could be described as HID as well as sports stadium and warehouse lighting. Solarc is a very specific subset of HID lamps. It is a brand name that encompasses a narrow group of miniature low wattage lamps manufactured exclusively by Welch Allyn. Solarc lamps are characterized by their low wattage, short arc gap, daylight color temperature, and miniature size.
