How to choose LED strip lights based on lumens per foot for various uses?

Table of Contents


LED strip lights are a popular lighting choice for homes and businesses due to their flexibility and energy efficiency. However, selecting the right LED strips can be overwhelming. One important factor to consider is lumens per foot, which indicates brightness. In this guide, we'll explore how to choose LED strip lights based on lumens per foot for various uses.

What are Lumens?

Lumens are a measurement unit used to quantify the brightness of light emitted by a source. Unlike watts, which measure power consumption, lumens indicate the actual brightness perceived by the human eye.

Lumens per Foot

Lumens per foot, also known as luminous flux density, measures the total amount of visible light emitted by an LED strip per foot of length. It provides a direct indication of the strip's brightness level, making it a crucial metric in choosing the right LED strip lights for your needs.

Factors Affecting Lumens per Foot:

  • LED Chip Quality: The quality of the LED chips used in the strip greatly influences its luminous efficacy. High-quality LED chips tend to produce more lumens per watt, resulting in brighter and more efficient lighting. 

  • Color Temperature: Color temperature, measured in Kelvin (K), affects the perceived brightness and ambiance of LED strip lights. Warmer color temperatures (below 3000K) tend to appear softer and more inviting, while cooler temperatures (above 5000K) provide a brighter, daylight-like illumination.

  • Strip Design and Materials: The design and materials of the LED strip can also impact its luminous efficacy. Factors such as the density of LEDs per foot, the efficiency of the reflective layer, and the quality of the phosphor coating can all affect the strip's overall brightness output.

  • Power Supply: Proper supply ensures optimal performance. It is best to follow the recommended 80%/30% rule when powering up your LED lights installation to ensure that you have enough power. The best way to check this is by using this Simple Power Supply Calculator - this will show the maximum and minimum capacity you’ll need for your installation.

Selecting LED Strip Lights Based on Lumens per Foot

  • Determine Lighting Requirements: Before choosing LED strip lights based on lumens per foot, it's essential to assess your specific lighting requirements. Consider factors such as the intended application, desired brightness level, and ambient lighting conditions in the space.

  • Calculate Lumens Needed: To determine the appropriate lumens per foot for your LED strip lights, calculate the total lumens required based on the size and brightness requirements of the space. This can be done by multiplying the desired illuminance level (measured in lux) by the area to be illuminated (in square feet).

This is a general guide when it comes to Lumens per foot lighting:

Accent Lighting and Mood Lighting: 

100 to 350 lumens per foot

Under Cabinet Lighting: 

175 to 525 lumens per foot

Task Lighting with low distance from light source:

280 to 437 lumens per foot

Task Lighting with higher distance from light source

500 to 1000 lumens per foot

Indirect lighting in a bedroom/hotel/vehicle/lobby: 

375 to 562 lumens per foot

Industrial lighting/signage/tube replacements: 

500 to 950 lumens per foot

  • Compare Lumens per Foot Ratings: When comparing different LED strip lights, pay close attention to the lumens per foot ratings provided by the manufacturer. Opt for LED strips with higher lumen outputs per foot for brighter illumination, especially in spaces where higher light levels are desired or if the project requires one.

In general, here are your benchmarks:

Task Lighting:

Needs brighter lights for visibility

Ambient Lighting: 

Requires softer, atmospheric glow

Large Spaces: 

Need brighter lights for adequate illumination

Small Spaces: 

Lower brightness prevents glare

Indirect lighting in a bedroom/ hotel/ vehicle/ lobby: 

375 to 562 lumens per foot

Industrial lighting/ signage/ tube replacements: 

500 to 950 lumens per foot

  • Consider Color Rendering Index (CRI): In addition to lumens per foot, consider the Color Rendering Index (CRI) of the LED strip lights. CRI measures the accuracy of the light in rendering colors compared to natural daylight. A higher CRI indicates better color accuracy, which is crucial in settings where color rendition is important, such as retail displays or art studios.

Practical Considerations for Different Applications

Residential Lighting

In residential settings, LED strip lights serve multifaceted purposes, from accentuating architectural features to providing functional lighting in kitchens, bathrooms, and closets. When selecting LED strip lights for residential applications, consider the following:

  • Kitchen Task Lighting: Opt for LED strip lights with higher lumens per foot to ensure adequate illumination for food preparation and cooking tasks.
  • Accent Lighting: Choose LED strip lights with customizable brightness levels to create dynamic lighting effects for ambiance and visual interest.
  • Closet and Cabinet Lighting: Select LED strip lights with moderate to high lumens per foot output to enhance visibility and facilitate organization in confined spaces.

Commercial and Retail Environments

In commercial and retail settings, LED strip lights play a pivotal role in enhancing visual appeal, highlighting merchandise, and optimizing operational efficiency. To achieve optimal results in commercial applications, adhere to the following guidelines:

  • Showroom and Display Lighting: Utilize LED strip lights with high lumen outputs and adjustable brightness settings to showcase products effectively and attract customer attention.
  • Office and Workspace Lighting: Incorporate LED strip lights with uniform brightness distribution to minimize glare and foster a conducive environment for concentration and productivity.
  • Outdoor Illumination: Choose weather-resistant LED strip lights with sufficient lumens per foot output to withstand environmental elements and ensure visibility in outdoor signage, pathways, and architectural accents.

Summary - Consider these factors when choosing LED strips:

  • Product Specifications
  • Lumens per Foot: Choose the right brightness.
  • Color Temperature: Select the desired ambiance.
  • CRI (Color Rendering Index): Ensure accurate color representation.
  • Quality and Efficiency
  • LED Chip Quality: Opt for better chips for longevity.
  • Energy Efficiency: Choose energy-efficient options.

In Conclusion

Choosing LED strip lights based on lumens per foot requires understanding your lighting needs and evaluating available options. By considering factors like brightness, ambiance, and efficiency, you can select LED strips that light your space effectively while saving energy. Make informed choices to brighten your surroundings with confidence.
