Before measuring the tube, there are several key considerations that we need to pay attention to.

Choose the right measuring equipment

Measuring LED and fluorescent tubes requires the use of specific measurement tools, such as photometers, color thermometers and color rendering index meters. Make sure you choose the right equipment for your measurement needs to get accurate results.

1.1 Choice of luminometer or photometer

For measuring luminous flux and luminance, you can choose a suitable photometer or luminometer. Note that when choosing an instrument, consider factors such as its measurement range, accuracy and stability.

1.2 Choice of color thermometer

To measure the color temperature of the lamp, you need to choose a suitable color thermometer. Make sure that the color thermometer can accurately measure the desired color temperature range and has good reliability.

1.3 Selection of color rendering index measuring instrument

Measuring the color rendering index of a lamp requires the use of a color rendering index meter. Select an instrument with high accuracy and reliability to ensure accurate assessment of the color reproduction capability of the lamp.

Understanding the measurement environment

It is important to understand the conditions of the measurement environment before performing the measurement. Make sure that the light conditions in the environment are stable and uniform to avoid interference with the measurement results from external light sources.

Prepare the sample

Make sure the lamp is installed and operating properly before performing the measurement. Wait for fluorescent tubes to reach a stable working condition, while LED tubes need to consider their thermal effects and control the measurement time according to the guidance provided by the manufacturer.

The measurement method of fluorescent tubes

The measurement of fluorescent tubes involves parameters such as brightness, color temperature and color rendering index.

Measuring luminance (luminous flux)

Use a photometer or luminometer to measure the brightness of fluorescent tubes. Make sure that the measuring instrument is placed in a fixed position and angle and record the measurement results. This will ensure consistency and comparability of measurements.

Measuring color temperature

Use a color thermometer to measure the color temperature of a fluorescent tube. Place the color thermometer close to the lamp and wait for a period of time to ensure that the fluorescent tube reaches a stable operating condition. Record the measurement results to evaluate the color temperature performance of the lamp.

Measuring Color Rendering Index (CRI)

Use a color rendering index meter to measure the color rendering index of a fluorescent lamp tube. Determine the color reproduction capability of the lamp under test by comparing it with a standard light source. Note that the accurate color rendering index value is obtained based on the comparison results of the standard light source and the lamp under test.

The measurement method of LED lamps

The measurement method of LED lamps is similar to that of fluorescent tubes, including brightness, color temperature and color rendering index and other parameters.

Measurement of luminance (luminous flux)

Use a photometer or luminometer to measure the brightness of LED lamps. Again, pay attention to the consistency of the measurement position and angle, and record the measurement results to ensure the accuracy of the measurement.

Measuring color temperature

Use a color thermometer to measure the color temperature of the LED lamp. Make sure the lamp reaches a stable operating condition and take the measurement. Record the measurement results to evaluate the color temperature performance of the LED lamp.

Measuring Color Rendering Index (CRI)

Use a color rendering index meter to measure the color rendering index of LED lamps. Determine the color reproduction capability of the LED lamp by comparing it with a standard light source. Based on the comparison results, obtain the exact color rendering index value of the LED lamp.

Precautions and tips

Before conducting the measurement, there are some precautions and tips that we need to understand.

Preparation before measurement

Before measurement, make sure that the measuring equipment has been calibrated and is in a charged state. Also, control the warm-up and stabilization time to ensure that the lamp reaches normal working condition.

Selection of the measurement position

When selecting a measurement location, consider the light distribution characteristics of the lamp. Ensure that the position chosen is representative of the light output of the entire lamp and that the measurement position is consistent.

Control of measurement time

According to the characteristics of fluorescent tubes and LED tubes, control the measurement time to avoid the influence of thermal effects on the measurement results. Especially for LED lamps, pay attention to the long measurement time may lead to thermal effects, which affect the measurement accuracy.

When selecting lighting equipment, it is important to consider the methods and considerations for measuring LED and fluorescent tubes. The right measurement equipment, understanding the measurement environment, preparing samples and mastering the essentials of the measurement method are all critical to obtaining accurate measurement results.
