Abstract:
A lamp has a safety circuit connected to first and second electrical connection terminals. A test is used to detect if the first and second electrical connection terminals are both connected to external power without an interfering impedance such a human body, and only then enable operation of the lamp. A time for the test is different from a time when another lamp in the system applies a test.
