Abstract
A lighting system and a method are provided with an adaptive power balancing scheme which reduces or eliminates flicker by sensing the operation of a lamp that is connected to an electronic transformer and adaptively controlling the drive circuit of the lamp to prevent unexpected reset of the electronic transformer. There is provided a lamp with a light source and a drive circuit for the light source; said drive circuit has a power stage for regulating a voltage supplied to the light source, an energy storage device, and control means arranged to selectively disable the power stage. Power is provided to the light source by the energy storage device when the power stage is disabled.
