The Digimark smart LED bulb stays on in the event of an unexpected power outage or load shedding. The emergency bulb is a direct replacement for a standard bulb, and the built-in battery will automatically charge when the bulb is switched on. In the event of a power outage, the intelligent light control automatically reduces the brightness of the bulb to ensure that the battery lasts as long as possible, and gives you 3 hours of backup light.

How does the lamp know the difference between light switch activation and power outage?
– The internal emergency management IC will detect the voltage of L and N
– When the voltage of a single line is cut off (light switch activation), there is still neutral voltages so the lamp will not go into emergency mode.
What is the effect of the lamp switching if there is no other load on the switched circuit?
– The emergency lamp will activate in emergency mode only when the IC cannot detect any voltage in the input cable (power outage), and when a loop is present in the external circuity. The loop is created by other components on the same electrical circuit within the installation.
– In this scenario the resistance between L and N is very small and the IC can detect this
What conditions make the lamp work during a power outage?
– When the IC cannot detect any voltage from the input cable (power outage)
– When a loop is present in the external circuitry. This loop is created by other components on the same electrical circuit within the installation. In this scenario the resistance between L and N is very small and the IC can detect this.
