Why not Converting Street Lights to Led? 

LED street lights were first introduced in or so, but they were not widely used and promoted until recent years. At that time, LED street lights weren&#;t widely used due to their high initial cost, and it takes several years for the energy savings to cover their cost.

But in the following years, In the context of energy saving and emission reduction, the outstanding advantages of led street lights in energy saving make them become the key municipal lighting products implemented by governments, thus pushing the industry to continuously carry out technological innovation. The performance of Led street lights continues to improve, and the cost is continuously reduced, even close to the cost of installing traditional street lights, which makes Led street lights progressively replace HPS street lights and become the most popular road lighting kits. 

However, this does not mean that there is no place for high-pressure sodium lamps. The fact is that the leading brand of lighting, Philips,  does not stop producing high pressure sodium bulbs and related components such as high pressure sodium ballast, and ignitors.  Most of the HPS lamps and accessories were bought for replacing old fixtures and a few for new projects. 

In this article, we&#;ll take a closer look at the differences between LED and HPS streetlights, and make an updated comparison of the two types of streetlights based on the newest situation to help you make an informed purchasing decision.  

Comparing the Pros of LED Streetlights and HPS Streetlights

Among the options for street lighting, LED and HPS is the most popular. While both types of lights serve the same purpose of illuminating streets and roadways, they have some significant differences in terms of their pros and cons.

Below, we&#;ll explore the pros of LED streetlights and high pressure sodium streetlight fixtures, comparing them to help you make an informed decision when choosing the right type of streetlighting for your needs.

Pros of LED Streetlights:

&#; Energy Efficiency: One of the most significant advantages of LED streetlights is their energy efficiency. To give the same brightness (Unit: lumens), LED lights consume significantly less energy than HPS lights, which can result in significant cost savings over time.

&#; Enhanced life expectancy: LED lights have a much longer life expectancy than HPS lights. It&#;s not uncommon for HPS lights to last between 24,000 to 28,000 hours, whereas LED bulbs can last up to 100,000 hours, which means fewer maintenance costs and fewer replacements.

&#; Customization: LED lights offer a wide range of customization options, including color temperature, brightness level, dimming mode, and beam angle, making it possible to create the desired ambiance and lighting effect.

&#; Instant On : LED lights turn on instantly, with no warm-up time required, making them ideal for use in areas with immediate illumination.

Pros of HPS Streetlights:

&#; Low Cost: HPS lights are relatively low-cost compared to LED lights, making them a cost-effective option for cities and municipalities with limited budgets.

&#; Warm Light: HPS lights emit a warm, amber-colored light that some people prefer over the cooler, bluish light of LED lights.

&#; Good for High-Pressure Areas: HPS lights are ideal for areas with high-pressure sodium vapor, such as industrial parks and manufacturing facilities.

Ultimately, the decision to choose one over the other depends on your specific needs and requirements for the street lighting project.

Comparing the Cons of LED Streetlights and HPS Streetlights

In addition to their respective pros, LED and HPS streetlights also have some disadvantages that must be considered when choosing the right type of street lighting. Below, we&#;ll compare the cons of LED streetlights and HPS streetlights, with a focus on initial installation costs, light quality, and maintenance and replacement costs.

Cons of LED Streetlights:
