Abstract: A retrofit kit allows retrofitting a non-LED canopy or other light fixture for use with LED lamps. The retrofit procedure removes the original electrical components and replaces them with components for use with LED lamps. The same components may be used to manufacture a new LED light fixture that can be used in the same applications as non-LED light fixtures.

Abstract: A power conversion unit converts an AC voltage into substantially constant DC current. The power conversion unit can be placed into an end cap of an LED lighting unit, to power LED modules. The power conversion unit uses capacitors and a bridge rectifier to perform the power conversion. The capacitors and bridge rectifier are selected to configure the power conversion and to produce the desired variable voltage substantially constant DC current.
