High Pressure Sodium Lamp Vs Led
This is because their lumen efficacy is much better.
High pressure sodium lamp vs led. Led lights have a wider variety of color temperatures along with higher cris. The large color spectrum of leds creates a widespread light output for better visibility and safety. Leds last longer than any light source commercially available on the market. Led lights have a wider variety of color temperatures along with higher cris.
Led area lights have a much easier immanence than high pressure sodium lights. Led lights are slightly more expensive than high pressure sodium lights at 10 20. Like metal halides high pressure sodium lights are omnidirectional which wastes light and makes them less efficient. The biggest differences between led and high pressure sodium lights are color temperature and cri.
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 lighting has excellent color rendering and better overall brightness. When it comes to high pressure sodium lights vs led energy consumption led lighting has become the industry standard. High pressure sodium lights have long warm up time usually around 15 20 minutes.
Led area lights have a much easier immanence than high pressure sodium lights. This not only provides more lumens per watt but also provides better overall lighting efficiency thanks to the lumens providing more visible light. 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. 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. They lose roughly 15 of their heat emissions which adds to their inefficiency. As mentioned previously hps lighting gives off a little more yellowish hue than the true white glow of the led lights. How do high pressure sodium lights affect workers.
Led fittings are instantly at full output. When comparing high pressure sodium vs led lighting options led wins with its high color rendering index cri. Hps light costs differ based on the particular fixtures but are cheap compared to leds. Sodium based lights require a warmup period.
