Before further testing and production are carried out, luminaires under development are subjected to a thermal endurance programme designed to test their durability in a variety of ambient temperature conditions.

The test is designed to stress the product by operating it for 168 hours at 10% above rated voltage and at an ambient temperature 10ºC higher than the maximum the product is designed for. Cyclic switching is automatically controlled and the test duration recorded.

The endurance enclosure can accommodate two luminaires and can reproduce ambience of up to 60ºC to test for any operating climate, particularly valuable when designing products suitable for the international market. The chamber has been designed to test for any ambient temperature in the world up to and including equatorial regions.
