How can you test and commission a lighting system for optimal performance?

1 Preliminary checks

Prior to testing and commissioning, it is essential to perform preliminary checks to guarantee that the lighting system is ready for inspection. This includes verifying that the power supply is available and stable, with circuit breakers and fuses in place and functioning. Additionally, check that the lighting fixtures, switches, sensors, dimmers, and controllers are correctly installed, aligned, and connected with no visible damages or defects. Furthermore, ensure that the wiring and cabling are correctly routed, labeled, and secured with no loose or exposed wires. Moreover, make sure that the lighting layout corresponds to the design drawings and calculations, while the lighting levels and distribution are suitable for the intended use of the space. Finally, confirm that the lighting system complies with applicable codes and standards such as the National Electrical Code (NEC), Illuminating Engineering Society (IES) guidelines, and Energy Policy Act (EPAct).

2 Functional tests

After the preliminary checks, you need to perform some functional tests to verify that the lighting system operates as expected. These tests should include testing the switching and dimming functions of the lighting system, ensuring the emergency lighting system provides adequate illumination and backup power, testing the lighting control system's communication with the fixtures and devices, and verifying that the lighting performance and quality meet the design criteria and user requirements. Examples of such criteria include illuminance, color temperature, color rendering, glare, flicker, and uniformity.

3 Commissioning report

After the functional tests, you need to prepare a commissioning report that documents the results and findings of the testing and commissioning process. This should include a summary of the lighting system design, specifications, standards, and codes; a list of the equipment and instruments used for testing and commissioning; a record of the preliminary checks and functional tests performed; a description of any issues or problems encountered during testing and commissioning; and a confirmation that the lighting system meets the design expectations and user satisfaction. This ensures that it is ready for operation and maintenance.
