Abstract
A lighting apparatus includes a solid-state lighting circuit, at least one ballast connection port and at least one low-frequency blocking impedance coupling the at least one ballast connection port to the solid-state lighting circuit. In some embodiments, the at least one low-frequency blocking impedance may be configured to block a DC offset. In further embodiments, the at least one low-frequency blocking impedance may be configured to block a nominally 60 Hz frequency component. The at least one ballast connection port may include a first ballast connection port and a second ballast connection port and the at least one low-frequency blocking impedance may include a first low-frequency blocking impedance coupling the first ballast connection port to a first terminal of the solid-state lighting circuit and a second low-frequency blocking impedance coupling the second ballast connection port to a second input terminal of the solid-state lighting circuit.
