Do Security Lights Use a Lot of Electricity?

Although security lights may be useful in providing extra security to a building or property, they raise concerns regarding the amount of power usage and energy bills. Generally, the amount of electricity used by security lights varies depending on the type of outdoor installation. The electricity consumption of a large commercial building will be greater than a typical home. Before installing security lights, you need to figure out the area where you need more lighting and explore the options for providing light in that area.

This article discusses the factors that determine the energy consumption of your security lights and how to save monthly bills on outdoor lighting.

Factors That Determine the Energy Consumption Rate of Security Lights

  • Type of Bulb

There are different types of outdoor lighting used in residential and commercial buildings. LED-based security lights are more popular because they save more energy compared to incandescent bulbs. They are durable, eco-friendly, and last longer than incandescent light fixtures. This means that if you install several incandescent bulbs for your outdoor lighting, you are likely to spend more on energy bills than if you had LED bulbs. Since LEDs last much longer, you will not have to replace them often, as it would add extra costs to your energy bills. Floodlights may seem like a good deal because they shine brighter and illuminate a wide area but they use a lot of energy based on the wattage.

  • Watts and Lumens

A watt is a unit of electrical power that indicates how much energy it takes for a light bulb to produce a certain amount of light. Although a bulb with a higher wattage uses a lot of energy that makes the light shine brighter. A lumen refers to the amount of light a lamp gives off. Unlike watts that measure energy use, lumens determine the light output of a bulb. If your security lights use a higher wattage than necessary, it will take a toll on your monthly energy bills as it uses a lot of electricity. Lighting experts recommend using Energy Star-qualified LED light bulbs for your outdoor lighting as they are passed through several quality tests before they earn that designation.

  • Control Options

This refers to the mechanism used to turn on your security lights during the specified period. Typical outdoor lighting uses a manual switch that needs to be turned on at dusk and switched off at dawn. You can choose to have timer switches that have been programmed to turn on the lights when you want them to be. Other homeowners use motion sensor lighting that only lights up at night when it detects movement. All these control options determine the amount of electricity consumed based on the number of hours your security lights have been on. You are likely to spend more on your monthly energy bills if you leave your security lights on throughout the day.

How Can I Reduce Energy Bills on Outdoor Lighting?

Although energy-efficient bulbs have revolutionized outdoor lighting, there are still other ways you can reduce your lighting use and energy costs. An overly lit area may be regarded as more secure but it takes up a lot of electricity. It is important to install bulbs whose wattage fulfills the atmosphere you would like to create in the outdoors. Use multiple switches when installing outdoor lighting in a large open-plan space. This allows you to restrict the use of lighting to the ideal areas that you want to use.

If necessary, install dimmers as they increase the lifespan of low-voltage lighting and reduce energy consumption by a significant margin. If you live in a low-traffic area, consider installing security lights with motion sensors. You can have them installed in areas that are prone to theft and burglary such as near your garage, next to the windows, or the front entrance. This ensures electricity is only used when required by turning on after detecting movement. Not all security lights need to be connected to the main power grid of your home. You can illuminate paths and driveways with lamps fitted with batteries that draw their energy from the sun.

Many homeowners use outdoor lighting to enhance the security and appearance of their homes. However, using high-wattage lamps with long hours of operation significantly increases your energy consumption. The best way to save energy with security lighting is to install energy-efficient lamps and control them effectively. You can do this by installing timers, motion sensors, and photocells that turn off the lights in the daytime.
