Quality Assurance of Airam Products in Kerava
See what is happening in the laboratory
Airam continuously takes measures to ensure product quality. Before new products reach the launch phase in their design, they are tested in the measurement laboratory located at the Kerava premises. The testing uses a goniophotometer, integrating sphere, and IP testing device, and various electrical safety standard tests are performed on the products.

Goniophotometer
The goniophotometer is a key tool for measuring the optical properties of luminaires. It measures the light distribution of the luminaire, providing accurate data on luminous intensity and light direction. This information is essential in lighting design, as it helps optimize light distribution in a space and ensures the luminaire meets design criteria and standards. The light distribution data obtained from the measurement can be used to design optimized and energy-efficient lighting solutions.
Integrating Sphere
The integrating sphere is a measurement device used to measure the total luminous intensity and spectral properties of light sources. The sphere has a highly reflective inner surface that evenly diffuses light, allowing for accurate and repeatable measurement results. This method can measure, among other things, luminous flux (lumens), color temperature (CCT), color indices (CRI, TM-30), light spectral distribution, and flicker. The data obtained with the integrating sphere is essential in the development and quality control of lighting products, ensuring that light sources meet required standards and performance requirements.
Dimming Testing in the Integrating Sphere
Dimming testing evaluates how the luminaire or lamp and dimmer work together at different dimming levels. The test can identify potential issues such as uneven dimming, possible color shifts in light, non-linear brightness adjustment, or noise produced by the dimmer.
IPx4 Test
The IPx4 test chamber is a device used to test the water resistance of luminaires according to IP ratings. The test chamber simulates the effects of rain and splashing water on products to ensure their suitability for outdoor or damp indoor environments. Testing is performed according to standards EN 60529 and EN 60598-1. In the IPx4 test, the device being tested is exposed to water jets from all directions.
Comprehensive Measurements
Airam’s test laboratory performs a wide range of measurements related to electrical safety and temperature management. Tests are conducted according to standards, ensuring the safety, functionality, and longevity of luminaires and lamps.

Temperature measurements monitor how warm a luminaire or lamp becomes during operation. The tests measure the temperatures of different components, such as the LED module, driver and luminaire housing. The temperature level and its distribution are important factors to assess, as excessively high temperatures shorten component lifespan and may affect luminaire performance.
The measurement results provide information on how the luminaire performs under real operating conditions and whether it maintains optimal performance throughout its service life. Temperature measurements are used in product development, quality assurance and compliance testing. They help ensure the design of energy-efficient and durable lighting solutions that operate reliably in a variety of environments.
Electrical safety testing ensures that luminaires and lamps meet safety requirements and prevent the occurrence of electric shocks, short circuits and other hazardous situations. Key testing methods include insulation resistance testing and protective earth continuity testing.
Insulation resistance testing measures the ability of the insulation materials in luminaires and lamps to withstand electrical breakdown. During the test, a high voltage is applied to verify that the insulation is adequate. This helps identify potential insulation faults that could otherwise result in electrical safety hazards.
Protective earth continuity testing verifies that the equipment’s earthing circuit is intact and capable of safely conducting fault current to earth. During the test, the resistance of the earthing circuit is measured to ensure that it does not exceed the limits specified by applicable standards.
