Abstract
A lighting circuit comprises a first light source arrangement and a second light source arrangement, of different types, in series. A driver delivers a controllable current to the light source circuit, with an adjustable DC component and an adjustable modulated component, for example an adjustable duty cycle of a superposed pulse width modulated component. This enables control of the contributions to the overall light output flux from the different types of light source.
