What Is Highway Lighting?

Highway lighting includes all forms of lighting that you can find on a highway - overpass, underpass, interchanges, exits and merge lanes lighting. Its purpose is to improve the driving experience in dark or night conditions.

What Are the Different Types of Highway Lighting?

There are many types of highway lighting - general street lighting, interchange high mast lights, underpass lights and overpass lighting, to name a few. LED Lighting Supply specializes in interchange high mast lighting.

How Does NAICS Code 237310 Relate to Lighting?

What Is the Typical Cost of Highway Lighting?

That depends on the light being replaced. An underpass light is typically inexpensive. A DOT high mast interchange cluster is more expensive since these are high power lights and there are typically many lights per pole.

Is It Best to Retrofit Highway Lighting or Use New Fixtures When Upgrading Highway Lights?

We believe it’s best to replace the fixtures. While we offer powerful retrofit options, they require optics to ensure the light is distributed properly. That being said, we do offer both, so contact us and we can work through the best option for your application.

Does It Make Sense to Use a Solar Highway Lighting System?

The issue with solar lighting is that it is somewhat limited in the amount of lumens it produces. The second issue is that it has a limited battery power. In case there are a few dark days, the lights may not operate at night.

What Is the Best Lighting to Use in a Highway Underpass?

Usually, we recommend wall packs or canopies for under passes. The fixture used will depend on the mounting required and the needed amount of light.

What Highway Lights Are Best for Piercing Fog?

Lower color temperatures work best, so if that is a major criteria, we would recommend 3000K - 4000K for foggy conditions.

Do You Have Portable Lights for Doing Work on the Highway?

We do not.

What Are the Best Lights for Highway Construction?

Flood lights produce aimable light so that you can easily illuminate the work area.

What Is the Best Lighting to Use in a Highway Overpass?

We would recommend pole mounted street lights for this application.

Do You Have a Retrofit to Replace Our Portable Lighting System Used on the Highway?

Yes, we can easily replace metal halide fixtures with power flood lighting on your portable lighting systems. They can be very compact and provide great light output.

What is the lumen output of highway high mast lighting?

Our most powerful fixture produces around 125,000 lumens - this may be way more than you need. You can easily replace 1000 Watt metal halide or high pressure sodium with much less. Also, optics are very important for highway lighting. It allows you to control the spread of light and to put more light on the ground. When the right optics are used, you will usually need less lumens.

What Is the Best Highway Tunnel Lighting?

Wall mounted / ceiling mounted linear fixtures are a good choice for highway tunnel lighting. They should also be able to withstand the environment of handling car exhaust.


What Optics Are Appropriate to Use on a Highway Application?

That all depends on the type of light. We have found that, for highway interchange, high mast lights and a wide beam optic work best in providing balanced lighting over a large area.

What Is the Best Mounting Height for Lighting on a Highway?

For highway interchanges, 60 to 80 feet or higher is desirable.

Are Your Fixtures Impact Resistant?

Yes, many of our fixtures have a high impact rating. Look for the IK01-IK10 icons on the product pages. IK10 is the strongest.

What Is the Best Height to Mount Highway Lights At?

That depends on the type of light and its purpose. But we usually see 30 feet plus.

What Is the Ideal Spacing for Highway Lighting?

We’d be happy to create a free lighting plan for you, to help you find the right answer. Every location, situation and roadway is different. A lighting plan will sort out the spacing criteria.

Should You Put Highway Lights on a Timer or an Intelligent Control System?

We always recommend simple controls (photocells) over complicated ones, but there are reasons you would want to use intelligent lighting controls (like monitoring of lights). There are always trade offs and complexity but more control versus simple but less options.
