Thermal Test

Thermal test is conducted under conditions representing normal service, to make sure no part of the luminaire; including the LED module and driver, the supply wiring within the luminaire, and the mounting surface; attains a temperature which would impair customer safety.

Thermal Test

The Thermal test is carried out in a closed room which is maintained at the test ambient temperature.

Surface luminaires are mounted on a standard 18mm medium density fibreboard (MDF) and orientated for wall or ceiling mounting. Recessed luminaires are mounted in a sealed recessed box representing a typical installation.

Temperatures are recorded using numbered probes attached to the points of highest temperature on the critical components, and to the exposed surfaces of the luminaire.

The luminaire is switched on and allowed to stabilise for 3 hours (16-24 hours for emergency luminaires) before temperature measurements commence. Temperatures are recorded every 10 minutes until a stable state is achieved, and the highest temperatures attained are noted.  

Compliance with the standard BS EN 60598-1 is met if the highest luminaire component temperatures attained are within the limits stated in Section 12 of BS EN 60598-1 and the luminaire does not become unsafe

Product testing is vital to ensure our luminaires remain up to our standard. To find out on other ways in which we test our luminaires, in our lab click below:
