Streetlight is one of the inventions that make our life so much better. It provides us with better vision and improves safety at night for driving and walking. We need streetlights around the housing area, highway and even industrial settings as the trucks and operations run 24/7.

Street lighting is widely using sodium-vapour light due to its cheap prices. But the sodium-vapour light has many weaknesses that it loses to LEDs on basically all areas. Yet, many have neglected the fact that LED brings many benefits over traditional street lighting.

Here, we will explain their differences and why LED is better for your factory streetlights.

LED Lights VS Sodium-Vapor Lights

There are a couple of reasons that LED lights are more practical than sodium-vapour lights for your factory streetlights. These elements may help you in decision-making.

Coverage area:

The area a sodium-vapor light can illuminate is much more limited than LED light. Meaning you need to install more sodium-vapour lights to cover the whole plant area. Oppositely, LED lights can cover larger areas, requiring fewer units.

Lifespan:

Short lifespan is one of the major weaknesses of sodium-vapour light. In contrast, LED lights have a relatively long lifespan compared to other lighting technologies. While sodium-vapour light has around 18,000 hours of lifespan, LED light’s lifespan can be greater than 40,000 hours.

Cost:

As mentioned earlier, by installing fewer units of LED lights, there will be a big cost difference. And the extremely low maintenance and replacement costs with LED lights are the significant cost benefit over the long term. Although sodium-vapour lights are relatively cheaper than LEDs, however, you will still need a few more units of sodium-vapour lights to attain the equivalent lifespan as LED light.

Color rendering:

Sodium-vapour light has the worst colour rendering index of -44 on the market as it is monochromatic. Meaning that the illuminated objects will appear shadowy, and you cannot distinguish colour under the sodium-vapour light. On the other hand, LED light has a very good colour rendering. In a score of 100, LED light achieves higher than 80 and some higher-end LED lights achieve almost 100.

Energy consumption:

Sodium-vapor light consumes higher energy than LED lights, and its energy consumption increases 10% over the life of the lamp to maintain its lumen output. Also, roughly 15% of the energy consumed will be turned into waste heat, meaning it is energy inefficient.

But LED lights consume 10% less power than sodium-vapour lights and produce very little waste heat. Thus, most of the energy consumed will be used to emit light and not heat.

Warm-up:

Sodium-vapour lights require a warm-up period of up to 15 minutes until the light arrives at its full power. In contrast, LED lights have faster switching, which requires no warm-up or cool-down period.

Waste Disposal:

Another major deficiency of sodium-vapour lights is that they have been known to start a fire if the lamp is broken. This can be very dangerous and makes it difficult to dispose of. As recommended, it is safest to break the sodium-vapour lights underwater and then subsequently dispose of the destroyed bulb.

Angle:

Unlike sodium-vapour light, which illuminates parallel to the floor, some LED lights are adjustable to illuminate a specific area.

While some LED lights are not adjustable, GlowOne has adjustable light distribution for different street configurations.

Not only does GlowOne LED light has all the benefits mentioned above that defeat sodium-vapour lights, but it also has many features that other LED lights do not offer.

For example,

• Protection against dust & moisture
• Various types of installation
• Easy to maintain and extend
• Special structure for pest control

As good as it sounds, you might be worried about the cost of GlowOne LED lights. But no worries, Syspex does offer a rental option that gives you much flexibility. You can even own the lights after 3 years of rental.
