LED Lighting vs. High Pressure Sodium
High Pressure Sodium Lighting |
vs. |
LED Lighting |
High pressure sodium left versus LED lighting right. LED lighting is closer to true daylight because temperature can be more precisely controlled. True to daylight translates to the perception of greater safety in parking garages. On roadways it means less visual fatigue. In architectural and accent lighting LED's allow improved lighting rendition. LED's start instantaneously and do not flicker or hum. They produce almost no heat and maintenance is reduced because of fewer replacements, and of course the main advantage: they require less energy.
