Light Testing

Lighting testing is an essential part of ensuring that lighting products meet the required quality standards for safety, performance, and reliability. Read on to know more.

Light is a fundamental aspect of our lives and plays a critical role in everything we do. From our brightness of screens to our homes’ illumination, we rely on light to navigate the world around us. And therefore, ensuring that the light we use is of the highest quality and consistency is essential. That’s where Light testing comes in. 

What Is Light Testing?

Light testing is integral to product quality testing because it ensures that the lighting products we use daily meet the required quality standards. This testing ensures that lighting products are safe, effective, and dependable for their intended use.

Take, for example, a light bulb. A light bulb’s lighting testing would include determining brightness, color temperature, and power consumption. A photometer would measure the bulb’s brightness, while a spectrophotometer would be used to determine the color temperature. A wattmeter would be used to measure power consumption. Furthermore, safety tests would be carried out to ensure that the bulb does not overheat or pose a fire risk. Now that you know what the term suggests, let us understand the Light testing significance.

Why Is Light Testing Important? 

Light testing is significant in product quality testing for a variety of reasons. Since lighting products play an essential role in our daily lives, and we rely on them to provide us with the light we need to navigate the world around us. As a result, these products must be safe, effective, and dependable. And Lighting testing ensures that lighting products meet these standards and are of high quality. 

Second, lighting products can be complicated, with numerous components and features. Testing can assist in identifying any defects or issues that may exist, allowing manufacturers to address these issues before releasing the products to the market. This can further help to reduce the risk of potential safety hazards, and product recalls, which can be costly and damaging to a company’s reputation. The type of testing also helps in ensuring that products meet regulatory requirements and standards. This is especially important in industries where lighting products, such as aviation, automotive, and medical, must meet stringent safety standards. Lighting testing ensures that these products meet the necessary criteria and are safe and effective for their intended use.

Last but not least, lighting testing can improve product quality by identifying flaws and allowing manufacturers to make necessary changes. This can result in more efficient, longer-lasting products with better lighting quality, benefiting both the manufacturer and the end user.

What Are The Important Standards To Be Considered For Light Testing? 

After getting familiar with the meaning and importance of light testing, let us not have a glance at some of the most critical standards that need to be considered for proper testing. 

  • IES LM-79 

This standard outlines how to measure the photometric performance of LED products, including their luminous flux, color, and electrical power properties. Photometric performance is defined as the distribution of light. 

  • IES LM-80

The methods for evaluating and reporting the lumen maintenance of LED light sources are laid out in this standard. Depending on accelerated testing, it offers a mechanism for estimating how an LED’s light output would diminish over time.

  • IES TM-21

With the help of this standard, producers will be able to extrapolate the lumen maintenance data received from LM-80 testing to determine the lifespan of an LED product.

  • IESNA RP-27

This standard offers standards for testing and assessing luminaires for outdoor lighting purposes. It offers suggestions for test methods, measuring approaches, and reporting.

  • ANSI C78.377

This standard specifies measuring and evaluating light source characteristics to determine how well they render color.

  • ASTM E308

You need to remember that this standard describes how to determine a light source’s chromaticity variables.

  • CIE S 025

Remember that this standard outlines the criteria for color rendering for various purposes.

You should know that these are only a few light testing standards. There can be more applicable requirements that you should also consider based on your demands.

What Is The Complete Procedure For Carrying Out Light Testing?

Now that you are aware of the standards for a lighting test let’s have a look at the procedure it incorporates. 

Step 1: Check the light source.

Before beginning, make sure the light source is functioning correctly. If the head of light is organic, ensure it is vibrant enough for the test, and check the lamp’s lightbulb to ensure it is not burned out or defective.

Step 2: Darken the room

Next, make the space as dark as you can. Because to analyze the light source you are testing accurately, you need to take out as much ambient light as possible.

Step 3: Measure the light source.

To gauge the brightness of the light source, use a light meter. Ascertain that the meter is calibrated for the light source you are testing. Now, take a reading from the meter after placing it near the start of the morning.

Step 4: Record the results

Now, you need to keep track of the outcomes of your light test. Also, note the light source’s intensity and any further pertinent details, such as the kind of light source or the time of day.

Step 5: Compare the results

Compare your light test findings to the suggested lighting levels for the area. Certain light levels may be advised for safety, efficiency, or other factors based on the application.

Step 6: Adjust the lighting

Modify the lighting as needed if the light levels are inadequate. This could entail switching the kind of light source, putting in extra lights, or moving the lights around.

Step 7: Repeat the test

Repeat the light test after making your lighting settings to ensure the light levels are sufficient.

You should always check the relevant regulations and standards for your sector or application because lighting specifications can vary based on the application.
