High Pressure Sodium Lamp Vs Led

Sodium based lights require a warmup period. Low and high pressure sodium lights are the only light whose source efficiency compares to leds values range between 50 and 160 lumens watt for lps and slightly less for hps. When comparing high pressure sodium vs led lighting options led wins with its high color rendering index cri.

Led area lights have a much easier immanence than high pressure sodium lights.

High pressure sodium lamp vs led.

How do high pressure sodium lights affect workers. This can take up to 20 minutes in some cases meaning your lights must be turned on at least 20 minutes prior to use to ensure maximum illumination. Led lights are slightly more expensive than high pressure sodium lights at 10 20. Led fittings are instantly at full output.

They lose roughly 15 of their heat emissions which adds to their inefficiency. The large color spectrum of leds creates a widespread light output for better visibility and safety. The biggest differences between led and high pressure sodium lights are color temperature and cri. Like metal halides high pressure sodium lights are omnidirectional which wastes light and makes them less efficient.

High pressure sodium lights have long warm up time usually around 15 20 minutes. When it comes to high pressure sodium lights vs led energy consumption led lighting has become the industry standard. The biggest differences between led and high pressure sodium lights are color temperature and cri. Led area lights have a much easier immanence than high pressure sodium lights.

Led lighting has excellent color rendering and better overall brightness. Most values for led system efficiency fall above 50 lumens watt. Hps light costs differ based on the particular fixtures but are cheap compared to leds. Most values for led system efficiency fall above 50 lumens watt.

Low and high pressure sodium lights are the only light whose source efficiency compares to leds values range between 50 and 160 lumens watt for lps and slightly less for hps. Led lights have a wider variety of color temperatures along with higher cris. Led lights have a wider variety of color temperatures along with higher cris. Leds last longer than any light source commercially available on the market.

As mentioned previously hps lighting gives off a little more yellowish hue than the true white glow of the led lights. This not only provides more lumens per watt but also provides better overall lighting efficiency thanks to the lumens providing more visible light. Hps lights have good lifespans around 14 000 hours though this is significantly less than leds. This is because their lumen efficacy is much better.
