Lighting emergency gear – what waveform should we use?

This article explains the pitfalls in providing DC or a modified sinewave to drive LEDs in emergency mode. Many LED luminaires have built-in drivers, so emergency gear must either simulate mains or attempt to drive the LED with DC power. Lower-power LEDs with low power factors are easiest to drive due to their simple circuitry. […]
