Quality criteria for drivers
The driver is one of the most critical components in LED solutions. The quality of LED luminaires not only depends on the LED light source and optical design, but also on the efficiency and reliability of the driver. A good LED driver must meet seven quality requirements:
- Lifetime.
- Efficiency.
- Power factor.
- Electromagnetic compatibility (EMC).
- Switching current (Inrush current).
- Waveform current.
- Mains voltage filtering.
Drivers are therefore crucial components in all LED solutions. High-quality drivers can be recognised by requesting the technical fact sheets from the manufacturer to check if the above quality requirements are met. ETAP always provides quality LED drivers, perfectly adapted to the solution and thoroughly tested in our labs.

Det specifika ljusflödet återspeglar förhållandet mellan ljusflöde och effektförbrukning. Precis som för lysrör måste man skilja mellan ljuskällans specifika ljusflöde (LED-komponent, mätt vid 25° eller 85°C anslutningstemperatur och med en standardstyrström) och armaturens specifika ljusflöde, inklusive drivdon och optik.
