Product Overview
The GE 92585 is engineered with ConstantColor™ technology, which prevents the "greening" effect common in older metal halide lamps. By maintaining a consistent 3000K color temperature throughout its 15,000-hour life, it ensures your space looks as intended from the first hour to the last. Its ultra-compact T4.5 tubular shape allows for highly efficient fixture designs, making it a favorite for retail displays, galleries, and high-end commercial interiors.
