Abstract
An amalgam fluorescent lamp is operated under high output and loading conditions by implementation of a control circuit to monitor and adjust lamp temperature. A variable density multi-element heater sleeve is connected to a controller which monitors the sleeve temperature and adjusts the power input to one or more of the sleeve segments. A separate control circuit maintains the lamp illumination output at a programmed level by monitoring a detected level of lamp output and comparing it with a pre-established reference signal.
