<p>A track lighting hybrid illumination system comprising a power supply circuit (11, 41, 22) having an input for connecting to a voltage source (12, 42) of low frequency for providing an output voltage with altered electrical characteristics, and a pair of conductors (19, 23, 43, 48) coupled to an output of the power supply circuit. A first lamp (29, 25, 31) is coupled to the conductors via a second power supply circuit (28, 26, 34), and at least one further lamp (29, 24, 25, 31) with electrical power requirements of a different characteristic to the first lamp coupled to the conductors.</p> |
