Abstract
A retrofit tubular lamp having a single switch device configured to selectively connect a first end and a second end of an input interface together. When the two ends are connected, a converter is bypassed whilst supplying power to a light emitting arrangement of the lamp. When the two ends are disconnected, power is provided to the light emitting arrangement via the converter. The single switch device is further configured so that, when disconnecting the two ends from one another, a creepage distance between the two ends is equal to or greater than a predetermined safety distance (i.e. a safety creepage is created).
