PHILIPS 250W ED28 E39 4100K HID Mercury Vapor Light Bulb

Mercury Vapor lamps feature low initial cost but have higher operating costs than HPS or Metal Halide due to its lower efficiency. The clear mercury bulb has a bluish green appearance and the Deluxe White has a higher color rendering. Mercury lamps get dimmer over time and rarely burn out so it is wise to replace them and restore light level.
