Start-Up Time

The start-up time, often also referred to as the warm-up time, describes the time it takes for a luminaire to reach a defined percentage of full luminous flux. According to the requirements of Regulation (EU) No. 1194/2012 for LED lamps with non-directional and directional light, the start-up time for 95% of the full luminous flux had to be less than 2 seconds. However, the Ecodesign Regulation 2019/2020 removed this requirement, as today's LED technology achieves full luminous flux almost immediately. Back
