1. Structural Differences
Par and surface lights differ in structure. The light source of a Par is a high-pressure mercury lamp encased in a paracoy glass shell. Surface lights are LED lamps with internal and external heat sinks. These structural differences directly affect their lifespan and brightness.
2. Brightness Differences
Par and surface lights also differ in brightness. Because Par lights use a high-pressure mercury lamp as a light source, they offer higher brightness and are suitable for use in residential and commercial spaces requiring strong illumination. Surface lights, on the other hand, use LEDs. While their brightness is lower, they offer superior color reproduction and are suitable for applications requiring true color reproduction.
3. Lifespan Differences
The lifespans of Par and surface lights also differ significantly. The high-pressure mercury lamp in a Par can easily extinguish during use. Prolonged use shortens the lifespan of the lamp, impacting the lifespan of the lamp. Surface lights, on the other hand, use LEDs, which offer a longer lifespan and are less susceptible to environmental influences, making them more durable.
