Are LED Street Lamps Better Than High-Pressure Sodium Lamps?

Lights are the essential parameters especially if you are living in a metro pollen city or in an urban area. With bright light, clearance to the roads, intersecting points and streets you also get the best visuals to the sight that becomes a plus point. However when it comes to LED lights for the street, there is always a discussion which is, are LED street lamps better than high-pressure sodium lamps or not?

Traditionally we used to see those dull yellow and orangery lightning at the roadsides followed by the buzzing sound that gives nostalgic feeling ever since LED came into our lives. But, when it comes to roads, driving lanes and commercial acres the bulb that burns the brightest is the winner.

And of course, when there is fog, and sun has set, the availability of the focused light ultimately becomes more like a demand.

LED lights are majorly used by everyone and its ubiquitous presence implies its usability. However there are also high-pressure sodium lamps out there that are somewhat making things perplexed. In this article when shall take a look at both and find out which one is better

What are LED Street Lights?

An LED light uses the emitting diode technology as the primary light source. Since these lights are durable, efficient and cost-effective, many commercial places including roads and streets use this. LED Street light readily lessens the electricity bills and makes sure to minimize 30% to 70% energy without a second doubt. Also its low maintenance design is something that makes LED lights worthy enough to be productive.

What are HPS lamps?

High pressure sodium lamps are pretty intense light bulbs that are best for streets and other commercial areas that need security lighting for sure. HPS is the blend of metals and gasses within the glass tube that let out the orange and white light that you commonly see in streets. HPS lamps feature 100 lumens per watt if you measure for photopic lightening and are mostly used outdoors as the light source for streets, parking, etc. however it can also be used indoors but for that color rendering is not a crucial part.

For indoors, high pressure sodium lamps are suitable for warehouse, shipping areas, garage, showroom, and other such places where the major parameter is commercial.

In a word, due to the amber light color these laps appear to be slightly dull and dim visibility to the human’s eyesight.

So are LED street lamps better than high-pressure sodium lamps?

In comparison to LED street lamps and high pressure sodium lamps there is a brief background you should have a look in. The HPS first came in the 1970s and these lamps got instant limelight for wet-lit areas and they also reduced the energy consumption as a whole. Moreover, the considerable amount of photopic illumination is also associated with high pressure sodium lamps.

However, with all of its orange light, HPS lamps are not as worthwhile as the LED street light is. High pressure sodium lacks lucid visibility and that is the major reason why we see LED Street lights everywhere around us. At work LED lights are better than high pressure sodium lamps because they offer you both cost-effectiveness as well as better vision to the sight.

White light source has been the best light for the street mainly due to better driver vision with up to 25% clearance. Due to its eco-friendly and also best for delivering real colors and much more benefits LED street lights are always the first preference. As compared to HPS lamps LED consumes between 40 and 80 percent less energy.

Some Major Downside of HPS Lamps and Lightings

With the new technology in the market especially in lights and electronics, the previous ultimately becomes somewhat obsolete. However, if we especially talk about the high pressure sodium lamps, they are less cost-effective in comparison with the LED light, also the poor visibility is there. They lack in delivering you the natural coloration because of the color limit and narrow color spectrum. For seeing objects on busy roads and motorways that is the major risk that cannot be taken at all.

The prolonged exposure of HPS lamps can be dangerous for the sight, but otherwise by being the shorter wavelength light, high pressure sodium lamps are not too unsafe for eyes.

Is HPS not in use anymore?

Although there are not any major perks of HPS lamps but still it is there and in use by many areas.  But for major cities, urbane areas, motorways and more commercial places LED street lights are the first preference. Moreover, its 50% more efficient approach for energy and durability is appreciable. With up to 15 to 20 years or bright burn performance, you get it right for commercial visibility.
