A typical outdoor wall light is likely to be a sodium vapor lamp. Sodium vapor lamps tend to have a very deep yellow or orange hue. Low-pressure sodium vapor lamps produce monochromatic emission, rendering colors poorly in exchange for the relatively better energy efficiency of conventional bulb technology. Interior solutions for wall lighting include traditional incandescent bulbs, but more typically mercury vapor bulbs. While each of these technologies has its advantages, industrial LED lighting outperforms all traditional alternatives in important ways.

LED Wall Lights vs Sodium Vapor Wall Lights: If you've ever walked around a parking lot or outside a building at night and noticed a deep yellow glow, chances are the lights you're seeing are sodium vapor. Low pressure sodium lamps emit a very deep yellow monochromatic light, while high pressure sodium lamps emit a slightly whitish yellowish light. Before the advancement of LEDs, these lamps were the best option for efficiency on the market. Let's take a look at what are the benefits of LED wall hanging lights? Why use LED wall lights instead of traditional lighting solutions?
