Abstract
A lamp assembly provides both instant light through use of an incandescent/halogen light/lamp source and an energy saving type light provided by a compact fluorescent light/lamp source. Both light sources are enclosed within a common envelope or outer bulb. First and second thermal sensors are provided in the lamp envelope at spaced locations to monitor the temperature of the lamp. When the sum of these two temperatures reaches a preselected value, power to the incandescent lamp source is terminated. Alternatively, when the difference these two temperatures reaches a preselected value, power to the incandescent lamp source is terminated.
