Patent abstract
A lighting ballast is programmable as to input and output parameters. Both operational characteristics and sensed data are used to control the ballast parameters. The ballast is configured to recapture as electrical energy heat produced by the lamp. The ballast is constructed in modular fashion with a power factor correction circuit module and a ballast control circuit module that snap together to achieve a large number of input voltage and lamp type variations with a small number of separate units.
