75 Watt Mercury Vapor Light Bulbs

Mercury Vapor HID Light Bulbs.

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.  

  • Mercury vapor is the original and now the oldest HID technology and has been supplanted by other HID types that offer higher efficiencies and better color properties.
  • Mercury lamps are used primarily for general street, parking and hi-bay industrial lighting applications where good efficiency and long life is desired and color rendering needs are moderate.
