Lighting fixtures like chandeliers add an extra layer of elegance and sophistication to any space, whether it’s a grand ballroom or a cozy living room. However, not all chandeliers are created equal. Some may look stunning but lack quality, durability, and safety standards. This is where tests and international certifications come into play.

How can GTG assist you with the tests on chandelier?

(1) Electrical safety test

To guarantee that your chandelier is safe to use, it needs to pass a series of electrical safety tests.

  • Insulation resistance test: the insulation resistance test is an essential electrical safety test that measures the quality of electrical insulation in the chandelier. This test is conducted using a megohmmeter, which measures the resistance of the insulation material. The test is designed to identify any insulation breakdown that could lead to an electrical shock or fire hazard.
  • Ground continuity test: the ground continuity test is another crucial safety test that checks the continuity of the electrical ground connection in the chandelier. This test is conducted to ensure that the chandelier is grounded correctly, and there is no risk of electrocution.
  • Dielectric withstand test: the dielectric withstand test is a high voltage test that checks the ability of the chandelier to withstand electrical stress without breaking down. This test is conducted using a high voltage tester that applies a high voltage to the chandelier. The test is designed to identify any weaknesses in the chandelier’s insulation that could lead to electrical shock or fire.
  • Current leakage test: the current leakage test is a safety test that checks the amount of current that leaks from the chandelier to the ground. This test is conducted using a leakage current tester that measures the amount of current that flows to the ground. The test is designed to identify any current leakage that could lead to electrical shock or fire.
  • Overload test: the overload test is a safety test that checks the chandelier’s ability to withstand a high load. This test is conducted using a high current tester that applies a high load to the chandelier. The test is designed to identify any weaknesses in the chandelier’s wiring that could lead to electrical shock or fire.
  • Short circuit test: the short circuit test is a safety test that checks the chandelier’s ability to handle a short circuit. This test is conducted using a short circuit tester that applies a short circuit to the chandelier. The test is designed to identify any weaknesses in the chandelier’s wiring that could lead to electrical shock or fire.
  • Polarity test: the polarity test is a safety test that checks the electrical polarity of the chandelier. This test is conducted using a polarity tester that checks the wiring polarity of the chandelier. The test is designed to identify any wiring polarity issues that could lead to electrical shock or fire.

(2) Photometric test

  • Lumen output test: lumen output test measures the amount of light emitted from a chandelier. It is an essential test as it determines the brightness level of the chandelier. The test measures the lumens per watt (lm/W) ratio, which indicates how efficient the chandelier is at converting electricity into light.
  • Color rendering index test: color rendering index (CRI) is a test that measures the ability of a chandelier to reproduce colors accurately. The test measures the color rendering ability of a chandelier on a scale of 0-100. The higher the CRI, the better the color rendering ability of the chandelier.
  • Color temperature test: the color temperature test measures the color of the light emitted from a chandelier. It is measured in Kelvin (K). The color temperature can range from warm white (2700K) to cool white (5000K).
  • Beam angle test: beam angle test measures the spread of light emitted from a chandelier. It determines the coverage area of the light.
  • Glare: glare is the amount of discomfort caused by bright light. Photometric testing can help measure the amount of glare produced by a chandelier, which is important for ensuring comfort in your space.
  • Flicker test: the flicker test is used to measure the amount of flicker emitted by the chandelier. Flicker can cause eye strain and headaches, and it is essential to ensure that the lighting fixture does not emit excessive flicker.

(3) Photobiological safety test

Photobiological safety tests are conducted to measure the level of safety of lighting products. The tests evaluate the potential risks that the lighting equipment poses to human health. The tests are conducted in compliance with the international regulations set forth by organizations such as the International Electrotechnical Commission (IEC), the International Commission on Non-Ionizing Radiation Protection (ICNIRP), and the American Conference of Governmental Industrial Hygienists (ACGIH).

  • Radiant power test: radiant power testing is done to measure the amount of UV and IR radiation emitted by a chandelier. This test is done using a spectroradiometer, which measures the power of the light at different wavelengths. The results are then compared to the safety limits set by the International Commission on Non-Ionizing Radiation Protection (ICNIRP).
  • Spectral power distribution: spectral power distribution testing is done to measure the wavelengths of light emitted by a chandelier. This test is important because different wavelengths of light have different effects on human health. For example, UV radiation can cause skin cancer, while IR radiation can cause eye damage.

This test is done using a flicker meter, which measures the frequency of flicker. The results are then compared to the safety limits set by the ICNIRP.
  • Glare test: glare test is done to measure the amount of glare emitted by a chandelier. Glare is a harsh, bright light that can cause eye discomfort and fatigue. This test is done using a glare meter, which measures the intensity of glare. The results are then compared to the safety limits set by the ICNIRP.

(4) EMC test

  • Radiated emissions test: this test measures the amount of electromagnetic radiation that the chandelier emits when it is in use. The chandelier is placed in an electromagnetic anechoic chamber, and a spectrum analyzer is used to measure the radiation levels. If the chandelier emits too much radiation, it may interfere with other electronic devices in the vicinity.
  • Conducted emissions test: this test measures the amount of electromagnetic radiation that is conducted through the power supply and wiring of the chandelier. The chandelier is connected to a spectrum analyzer, and the levels of conducted emissions are measured. If the levels are too high, the chandelier may cause interference with other electronic devices.
  • Electrostatic discharge test: this test measures the chandelier’s ability to withstand electrostatic discharge, which can occur when a person touches the chandelier. A high-voltage generator is used to simulate the discharge, and the chandelier is monitored for any malfunctions or failures.
  • Immunity to electrostatic discharge test: this test measures the chandelier’s ability to withstand electrostatic discharge from external sources. The chandelier is exposed to a high-voltage generator, and the levels of discharge are increased until the chandelier malfunctions or fails.
  • Radiated susceptibility test: this test measures the chandelier’s ability to withstand electromagnetic radiation from external sources. The chandelier is placed in an electromagnetic anechoic chamber, and a spectrum analyzer is used to measure the levels of radiation. The levels are increased until the chandelier malfunctions or fails.
