A21 - Clear - 8,000 Life Hours - 660 Lumens - 130 Volt
The Philips 222042 69 watt traffic light bulb is an affordable, long-life lamp. A five support filament ensures the bulb will resist vibration and last its rated 8,000 hours while its brass base prevents the lamp from freezing in its socket -- a major advantage for traffic signals. Please note that this lamp should only be operated in a horizontal position.
