Foot Candle Chart & Lumens to Foot Candle Conversion Calculator

What is a Foot Candle?

A foot-candle measures light intensity, equivalent to one lumen of light per square foot. It measures the light that reaches a surface, while lumens measure the quantity of light produced by a fixture.

Footcandles, equivalent to approximately 10.764 lux, are vital for measuring light intensity in commercial, industrial, and sports lighting. They define the required lighting levels for various environments, ensuring safety and functionality.

As set by organizations like OSHA, compliance with footcandle and lighting standards is essential for safe and adequately lit workplaces. In sports lighting, footcandles ensure optimal visibility for players and spectators.

OSHA Lighting Requirements

OSHA, the Occupational Safety and Health Administration, was created to protect workers by ensuring that working conditions were safe and as risk-free as possible.

To ensure that all industrial and commercial workplaces have effective and adequate lighting without being excessively bright (or without glare), OSHA developed standards as part of its safety initiative.

Glare and excessive lighting can cause headaches and eyestrain to individuals over time. Read more about OSHA guidelines from the United States Department of Labor.

Foot Candles Calculator

What is a Foot Candles Calculator?

A foot candles calculator is a simple tool that allows you to estimate the number of fixtures you will need to properly light an interior space. It’s a starting point to give you a rough estimate of the approximate fixture count.

Another (better) option is to ask us to do a Lighting Plan for you. We can do these for indoor and outdoor spaces. It will also give you a fixture count but will provide you with additional information like light balance and visually show you how well-lit the area will be.

Foot Candles & Lighting Plans

Why are Foot Candles Important?

Foot candles are an extremely important part of designing an effective lighting setup. They are the only way to tell if an area is receiving the intended light levels.
And, although this is important in any type of business, commercial and industrial facilities need to have appropriate lighting levels for both employee safety and efficiency.
It’s so important that OSHA has specific foot candle requirements for certain spaces and industries.

Recommended Light Levels

Lighting systems are not equal. What may be ideal for one location may be unsuitable for another. For instance, a big box store does not need the same amount of light as a packaging warehouse. Even if two facilities have the same square feet, the activities carried out may be different. The work done in a building typically determines the fixtures needed for its associated lighting. This is why choosing lighting for a space should not be a “one size fits all” approach. Foot candles are required by OSHA for workplace lighting measurements. In this article, we’ll give foot candle recommendations for different types of environments.

What is Luminous Flux?

In the science of photometry, it is a measurement of perceived light or brightness by a human. It is sometimes also referred to as scotopic lumens (light perceived by the eye) versus photopic lumens (light measured by a device)

Foot Candles Versus Lux – What’s the Difference?

Foot candles and lux are both light measurement readings. They are just represented by different scales.

Understanding Lighting Plans

A Photometric Study, or Lighting Plan, is a report detailing the light levels and light distribution for a location, either indoors or outdoors. It’s done by software that’s specifically created to do lighting design.

Lighting Plans allow you to simulate space, add lighting fixtures, and set mounting heights and fixture locations within the software model.

The software calculates light levels and how balanced the light is and produces a report showing average, maximum, and minimum foot candles.

For this discussion, the numbers we discuss are the average recommended foot candles. Just as important is the max/min ratio the study calculates. The higher this number is, the spottier the lighting.

So, it’s one thing to hit the recommended average. It’s another to design a lighting solution with even light distribution. A lighting plan study will provide you with this information.

How To Calculate Foot Candles from Lumens?

Understanding Lumens

What is a lumen? A lumen is a measurement of light output created by one bulb, lamp, or fixture. We use lumens to indicate the brightness of a bulb or fixture – how much light it produces. Lumens are a far more accurate representation of the light’s capacity than watts used to make light.

Converting Lumens to Fc – or – Foot Candles to Lumens

A foot candle (also known as fc, ft-c, or lm/ft2) is a light intensity measurement. One foot candle equals 10.76 lumens. You can convert foot candles to lumens by multiplying the number of foot candles by 10.76.

The calculation of foot candles for industrial lighting is made by taking the total number of lumens and multiplying that by 0.001496. For example, 538 lumens x 0.001496 watts = 0.805 watts per square meter so your 50 foot-candles would equal 0.805 watts per square meter.

In the simplest sense, you can install one light in a room above the floor and, while using a light meter, walk around the floor and take foot candle measurements. The amount of light directly under the installed fixture will be brighter than the light in the corners.

Using this same room, you can install four fixtures evenly throughout the room. As you walk around the room, everything is brighter. The light meter is showing higher foot candle measurements throughout the room. The corners are brighter.

That’s all this is. Lights produce lumens, and as you add more lights, the foot candle measurements will increase throughout the space.

The takeaway: the more lights you add, the higher the foot candle readings will be.

Lumens Per Square Foot

What are lumens per square foot? By definition, one lumen per square foot is one foot candle. This means that:

• 20 lumens per square foot: 20 foot candles


• 40 lumens per square foot: 40 foot candles


• 80 lumens per square foot: 80 foot candles

Like the previous discussion of lux, lumens per square foot is an additional description of what a foot candle is. So why do we think of lighting in terms of foot candles and not lumens per square foot?

Mostly because the tools we use to create lighting plans provide us with results in foot candles. However, it’s easy to convert the foot candle measurements we provide to lumens per square foot measurements.

Lighting Plan Software – How it Works

Lighting plan software is a computer-generated lighting model that understands the physical characteristics of how many lumens a light produces and how it distributes its light. The software allows you to install lights in a software “space” and run calculations by simulating foot candle readings on the ground. It’s extremely accurate, and the report generated provides details on light levels and light balance within the space.

The takeaway: we provide free lighting plans for our commercial and industrial customers, electricians, and electrical contractors. Scroll to the bottom of this page to ask for yours.

Understanding Light Efficiency – This is What Saves You Money

Even amongst LEDs, not all bulbs are created equal. Though they are all more efficient than options like fluorescents and metal halides, not every LED is equally efficient.

This is another reason why it’s important to pay attention to the lumens of an LED light instead of the watts. In many cases, a higher quality LED with a lower wattage can produce a brighter light than one that has a higher wattage.

How to Choose the Right Fixture to Meet the Foot Candle Requirements

Now that you understand what the foot candle levels might be for your project, how does that translate into buying the right fixture, or the right type of fixture? That’s where we can help. LED Lighting Supply provides two distinct services:
