LED strip lights are flexible, energy-efficient and highly versatile. They come in various colours, sizes and brightness levels. LED strip lights offer a cost-effective way to transform a space. You can cut the strip light per your requirements, and they are relatively easy to install. However, like any other electronic device, LED strips also need to electricity to operate. Therefore, you ought to know your LED strip light’s power consumption to maintain energy efficiency. In this blog, we will explore LED strip lights wattage, compare LED strip lights with other lights, and learn how to calculate the wattage consumption. 

Factors Influencing LED Strip Lights Power Usage

Here is a breakdown of the factors influencing the electricity usage of LED light strips:  

• LED strip light wattage ratings 

LED light strips come with different wattage ratings, indicating the amount of power they consume per unit of time. Lower wattage strips generally use less electricity, making them more energy-efficient. Higher wattage strips may provide brighter illumination but consume more power.  

• Length of the LED strip 

The length of the LED light strip directly influences its electricity usage. Longer strips typically have higher power requirements. When calculating electricity consumption, consider the total length of the installed LED strip.  

• Brightness levels and lumens 

LED light strips offer various brightness levels measured in lumens. Higher brightness generally corresponds to higher power consumption. When choosing LED strips, balance the desired illumination with energy efficiency to meet your specific lighting needs.  

• Colour and colour temperature 

The colour and colour temperature of LED light strips can affect their power usage. RGB (Red, Green, Blue) or RGBW (Red, Green, Blue, White) strips, may consume more power than single-colour strips. Additionally, warmer or cooler colour temperatures can influence energy consumption.  

• Dimming and controls 

LED light strips with dimming capabilities and smart controls can help manage electricity usage. Dimming the lights reduces power consumption, and smart controls allow you to customise brightness levels for optimised efficiency.  

Calculating LED Strip Lights Power Consumption  

To determine how much electricity your LED light strip uses, you can use the following formula:  

Electricity Consumption (in kWh) = (Wattage/1000) × Operating Hours  

• Here:  

• Wattage is the wattage rating of your LED light strip.  

• Operating hours are the number of hours the LED light strip is in use.  

Suppose you have an LED light strip of 1 metre in length with a wattage rating of 10 watts/metre, and you run it for 4 hours a day.  

• Electricity Consumption (in kWh) = (10/1000) × 4  
• Electricity Consumption = 0.01kWh × 4 hours  
• Electricity Consumption=0.04kWh  

In this example:   

The LED light strip consumes 0.01 kWh for every hour of operation (since the wattage is 10 watts, we divide by 1000 to convert to kilowatts). If you run the LED light strip for 4 hours, the total electricity consumption would be 0.04 kWh.  

Comparing LED Strip Lights with Other Lighting Options  

Here is a detailed comparison of incandescent bulbs, and fluorescent tubes, and a discussion of the advantages of LED technology in various scenarios:
