This test involves measuring the electrical current flowing through the fixture when it is not in use. If the current is within the specified limits, the fixture passes the test.
  • Ballast test: ballast tests are carried out to ensure that the ballast in the fluorescent light fixture is functioning properly. This test involves measuring the output voltage and current of the ballast. If the output is within the specified limits, the fixture passes the test.

(2) Photometric test

  • Luminous flux test: the luminous flux test measures the amount of light emitted by a bulb, expressed in lumens. This test is conducted in a dark room, where the light bulb’s output is measured using a photometer. The photometer records the amount of light that falls on a specific surface area and calculates the lumens produced.
  • Luminous intensity test: the luminous intensity test measures the amount of light emitted by a bulb in a specific direction. It is expressed in candelas, and it is conducted using a goniophotometer. The goniophotometer measures the light emitted by the bulb in various directions and creates a graph of the bulb’s light distribution.
  • Color rendering index test: the color rendering index (CRI) test measures the bulb’s ability to reproduce colors accurately. The test is conducted by comparing the color of an object when illuminated by the bulb in question and a reference light source. The CRI is expressed as a percentage, and bulbs with a CRI of 80 or above are considered to have good color rendering capabilities.
  • Color temperature test: the color temperature test measures the color of the light emitted by the bulb. It is expressed in Kelvins and is conducted using a spectrophotometer. The spectrophotometer measures the intensity of light emitted at different wavelengths and calculates the color temperature.

(3) Photobiological safety test

Photobiological safety tests are designed to measure the potential hazards of light sources on human skin and eyes. There are several tests that manufacturers use to determine the safety of their products, including the Spectral Irradiance, Retinal Blue Light Hazard, and Ultraviolet Radiation Tests.

  • Spectral irradiance test: the Spectral Irradiance Test measures the intensity of light emitted by fluorescent light across different wavelengths and determines the level of risk for photobiological hazards. This test is important because it helps manufacturers to identify the frequency of light that is most harmful to human skin and eyes.
  • Retinal blue light hazard test: the Retinal Blue Light Hazard Test is designed to measure the potential hazards of blue light on the retina of the eye. This test is important because blue light has a shorter wavelength than other colors of light, which means it can penetrate deeper into the eye and potentially cause damage.
