(2) Photometric test
A photometric test is a type of light measurement that assesses the amount of light produced by a light source. This test is essential to ensure that the light source is providing the necessary illumination.
There are three main photometric tests conducted on street lamps:
a. Luminance measurement: this test measures the amount of light emitted by a light source. It’s essential in determining the brightness of the light source.
b. Illuminance measurement: this test measures the amount of light that reaches a surface. It’s essential in determining the level of illumination provided by a light source.
c. Light distribution measurement: this test measures the direction and pattern of light emitted by a light source. It’s essential in determining the uniformity of light distribution.
(3) Photobiological safety test
Photobiological safety tests are conducted to assess the potential risks associated with exposure to light sources, including street lamps. These tests evaluate the effects of light on the human eye and skin, ensuring that the light emitted by street lamps falls within safe limits. Here are some common photobiological safety tests for street lamps:
- Photobiological risk assessment: this assessment involves evaluating the spectral characteristics of the light emitted by the street lamp and assessing its potential risks to the eyes and skin. It considers factors such as blue light content, ultraviolet (UV) radiation, and glare.
- Blue light hazard test: blue light emitted by certain light sources, including LED street lamps, has the potential to cause retinal damage. Blue light hazard testing measures the spectral characteristics of the light and determines its potential risk to the eyes.
- UV radiation test: some street lamps, particularly those using certain types of lamps, may emit UV radiation. UV radiation testing assesses the UV content of the light emitted by the street lamp to ensure it falls within safe limits.
- Glare assessment: glare from street lamps can cause visual discomfort and reduce visibility. Glare assessment tests evaluate the luminance and distribution of light from the street lamp to determine potential glare issues.
(4) EMC test
- Radiated emissions test: this test measures the electromagnetic radiation emitted by the street lamp and ensures that it does not interfere with other electronic devices. The test typically involves placing the street lamp in a shielded room and measuring the radiation levels at various frequencies.

- Voltage variation test: this test measures the street lamp’s ability to withstand variations in the power supply voltage. The test involves simulating variations in the power supply voltage and measuring the street lamp’s response.
(5) Energy efficiency test
Energy efficiency tests on street lamps are important to ensure that they are using energy efficiently and minimizing wastage. One of the primary tests that street lamps undergo is the luminous efficacy test. This test evaluates the light output of the lamp per watt of power consumed. The higher the luminous efficacy, the more energy-efficient the lamp is.
(6) Mechanical tests
- Impact resistance test: to simulate the effects of a vehicle collision, street lamps undergo an impact resistance test. A pendulum is swung at the lamp to determine its ability to withstand external forces. The test ensures that the lamp will not shatter or break if a vehicle hits it.
