Are LED Street Lights Brighter?

Most people are wondering which street lighting source is better: LED or HPS. You are definitely not a light engineer who can know which lighting source is perfect for outdoor use. You may consider LED street lights the same as high-pressure sodium lighting systems. But it is not really true! With the advancement in technology, all people want to replace the outdoor lighting system with LED street lights because of its various advantages:

 ● Less electricity cost. 

 ● Less carbon footprint. 

Well, you can read our other article to know the features of LED street lights in detail. If you want to know the difference between LED vs HPS lighting, then you are at the right place. In order to give a clear answer to your query, we have discussed the cost, efficiencies, performance and many more of these two technologies.

Light Emitting Diode Street Light

It is the best and preferred lighting system because it is more energy-saving than other types of outdoor lighting. If you compare it with HPS technology, then the LED lighting system is 50%more efficient. Due to these features, most people are shifting towards light-emitting diode outdoor lights.

High-Pressure Sodium Street Light

This is the most common type of street light that you see everywhere. If we talk about the production of glow, it produces a distinctively yellow-orange glow. This light technology is used in manufacturing sites, parks, sides of the road etc.

But nowadays, people replace high-pressure street lights with environmental and eco-friendly LED lights.

Below we have mentioned the characteristics of these two technologies that can clear your mind well. Keep reading the following sections.

LED Street Light Vs Normal Street Light

LED street lights win with longevity over! Its life cycle is about 50,000 hours. Furthermore, it emits less heat and much more!

1. Color Rendering Index(CRI)

The color rendering index basically determines how the light source reflects the color of other objects.

CRI criteria for street lights are given below:

 ● In between the range of 75 to 100: Excellent

 ● 65-75: Good

 ● 0-55: Poor

LED street lights have CRI in the range of 65 to 95, which is excellent! It means light can illuminate the color of an object. At the same time, HPS street lights have CRI in the range of 20 to 30.

2. Efficiency

Efficiency is always measured in lumens per watt. It basically describes the ability of light to provide more brightness and consume less energy. It is best to use those lights that have the highest efficiency.

 ● The efficiency value for most LED street lights is 114 to 160 Lm/watt.

 ● At the same time, for HPS street lights, this efficiency lies in the range of 80 to 140 Lm/watt.

Now you can clearly understand that LED lights are brighter and more energy efficient.

3. Heat Emission

Straightforwardly, those lighting systems are the best that emit no or less amount of heat. Or you can relate the energy efficiency with the heat emission factor.

More energy efficiency means less heat is emitted. LED street lights don't emit a large amount of heat. At the same time, HPS street lights emit large amounts of heat that are not good for the environment. So, again LED lights win the race over heat emission.

4. Correlated Color Temperature(CCT)

How warm or cold the CCT factor determines the lighting. Street lights with the 3000K CCT value are considered good.

 ● For LED street lights, CCT values lie in the range of 2200K to 6000K.

 ● At the same time, the CCT value for HPS is +/-2200.

So, LED street lighting systems are good in terms of CCT value.

5. On/Off

How fast the light responds when the switch is on or off? LED street lights are also better in terms of on and off because there is no warm-up or cool-down.

6. Directionality

The directional factor determines how much light is focused in one direction. If we talk about LEDs, they illuminate light at an angle of 360 degrees.

At the same time, HPS illuminates at an angle of 180 degrees. So, LED street lights are highly directional than any other type of lighting system.

7. Visible Light Emission

The light spectrum must b lie in the visible region that is good for human health and the eye. The visible region light has a range of wavelengths from 400nm to 700nm.

Both light technologies give the light spectrum in the visible region, but the light-emitting diode has a stronger light emission.

8. Heat Tolerance

This factor determines the ability of light to withstand high values of temperature. It is good to choose those that have high heat tolerance.

 ● The value of heat tolerance of LEDs is 75 to 100-degree Celsius. 

 ● At the same time, for the HPS street light, the value is 65-degree Celsius. 

So, LED street lights are better in terms of heat tolerance.

LED Street Lights: Maximum Brightness, Less Maintenance and Better Performance

Less maintenance is required by the remote solar LED street lights. They shine brighter than the typical high-pressure sodium street lighting system. LED street lights win all competition in terms of longevity, maintenance and money.

You don't need to replace it frequently. If you are under the yellow color of the HPS street light, then replace it now with LED street light and enjoy the cool color!

The Bottom Line

You can quickly conclude that LED street lights are better than any other type of lighting technology. LED street lights are:

 ● Cost-efficient

 ● Energy-efficient

 ● Brighter

 ● Create no any pollution

 ● Smart lighting system
