How to Install a Ground Light





There are several steps involved in the installation of ground lights. For one, you need to prepare the ground. For this, you must dig a hole that is at least 10 to 12 inches deep and 6 inches wider than the light fixture’s diameter. Next, you should fit a piece of PVC pipe inside the hole with the wire snaking through it. This piece of pipe should be four inches in outside diameter and 10 to 12 inches long. You can purchase this pipe at a home improvement store.

Next, you need to choose the appropriate type of wire and conductor. While low voltage lights can be installed directly into the ground, line voltage lights require the use of liquidtite conduit. Once the conduit is installed, you can feed the wire through it and into the ground light fixture housing. Finally, you must make sure to secure all wire connections using UL listed waterproof silicone filled wire nuts. To prevent water damage, you can also use Teflon tape or mastic putty to keep the wires secure.

Before installing ground light fixtures, you should check the installation guide thoroughly for any errors or omissions. It is important to note that ground lights should have an IP-68 rating. Having a lower IP-value can cause them to be susceptible to water, so be sure to purchase a ground spot with an IP-68 rating.

Common issues

There are several common issues with ground lights. First, the bulbs can become overheated if exposed to direct sunlight. To avoid this problem, be sure to purchase a ground light that is rated for ambient temperature. Another common issue is a blown fuse. In this case, you’ll need to contact an electrician for repair.

You can also check the bulb filaments with an ohmmeter. If they are broken, the meter should beep. If it does not, then the switch or circuit is likely to be to blame. If your meter is set to DC volts, you can use the 20 volt range, or you can use the auto-range setting.

Common applications

In-ground lighting is a common fixture for a variety of uses. Most people use them on soft dirt and turf, but they can also be used on brick and stone patios and wood decks. They can be installed out of traffic paths and can highlight interesting features. They are also ideal for illuminating a garden or other feature.

Ground lighting is a cost-effective and maintenance-free solution for indoor and outdoor lighting. It can illuminate pathways and other areas while creating a calming atmosphere. Common applications include campsites, canal paths, and campuses. The lights can also be used to create mood lighting. These applications are just a small sample of the numerous uses for ground lighting.


When purchasing a ground light, it is important to understand the specs for it. The height of the light must be at least 17 inches and it must not exceed 40 inches. It must be UL 1598 listed for wet locations and be rated IP66. It should also comply with FCC CFR Part 15 and meet the IES LM-80 standard.

The L-851T is rated for a minimum of 2 candelas of coverage at an angle of up to six degrees. In addition, it must be able to cover 15 to 90 degrees vertically. It can be installed directly into the ground or mounted on a standard FAA light base. The L-851 is available in a toed left or straight fixture. The L-851T is also rated for a horizontal beam spread of 180 degrees.

The MSSLC is a group of outdoor lighting Users who share knowledge and experiences. It also develops guidance and tools to support its Users. The Model Specification is not intended to be a standard specification. It should be used as a modular reference for drafting documents. However, it is not a mandatory requirement for a ground light.

When specifying ground lighting for an airport, the FAA issues several Advisory Circulars and Engineering Briefs. AC 67, for example, explains how to use alternate light sources in airports and in obstructions. The American National Standards Institute, American Society for Testing and Materials, and the Institute of Transportation Engineers (ITE) also publish standards.


If you’re thinking about installing photocells for your ground light fixtures, you need to make sure they are installed properly. First, it’s important to place the photocells in a strategic location. They should not face south because too much sun will affect their effectiveness. Second, you must make sure the photocells receive the proper electrical power. Finally, cracks within the assembly can cause intermittent lighting or even no light activation. If this happens, you’ll have no choice but to replace the photocells.

A photocell works by detecting ambient light levels and turning on and off exterior lights accordingly. Photocells are a great choice for many light-sensitive applications. They’re also a great choice for security applications, as they are low-cost, low-power, and don’t wear out.

The sensitivity of a photocell can be expressed in two ways: as the electrical output of the device at a given illumination level, or as a proportion of the light level measured. Often, this measurement is expressed in units of lux (light intensity), or in thousands of lux (illuminance). The level of illumination required to trigger a photocell depends on its wavelength and spectral composition.

When used with microcontrollers without analog pins, photocells can be a useful option. Because they can be used to control single lamps, they’re convenient for turning them on and off. Alternatively, lamp base photocells screw into lamp sockets and turn any lamp into an automatic lighting system. These devices must be installed in each socket.


Proper maintenance of ground lighting fixtures is essential to the safety and functionality of the entire system. It is essential to change bulbs at regular intervals and replace damaged fixtures as needed. It is advisable to replace bulbs with energy-efficient varieties. In some cases, homeowners may wish to change to LED lighting for its energy-efficiency and long-lasting light.
