Abstract
A solid-state lighting arrangement (10) designed for use within a lighting fixture (100) having existing ballast circuitry (110) for powering one or more discharge lamps. The solid-state lighting arrangement (10) includes a solid-state light source (50) and a startup delay circuit (60) coupled to light source (50). During operation, delay circuit (60) prevents application of power to light source (50) for a startup delay period, so as to provide compatibility with a wide variety of existing ballasts, as well as enhanced compatibility with the protection circuitry that is present in many existing ballasts.
