Abstract
A tubular LED lamp designed for connection to a high frequency ballast. An electrically conductive screen is provided with an electrical connection between an internal node, such as an internal LED ground, and the screen. This provides a low impedance path5 for leakage currents which bypasses the LED string and thus prevents glow.
