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.
