A lamp or luminaire with LED technology is powered by a driver:
- can be integrated into the bulb (tube or lamp for retrofit) : in this case refer to the power indicated on the lamp
- if separated : in that case it is necessary to take into account the power dissipated in the driver and the power indicated for one or several associated LED modules.
This technology has a very short start-up time. On the other hand, the inrush current at the powering is generally much higher than for fluorescent lamp with electronic ballast.
Note: The power in Watts indicated on the LED module with a separated driver doesn’t include the power dissipated in the driver.
