Input: Consider Input: Passage: Metal-halide lamp -- A metal-halide lamp is an electrical lamp that produces light by an electric arc through a gaseous mixture of vaporized mercury and metal halides (compounds of metals with bromine or iodine). It is a type of high-intensity discharge (HID) gas discharge lamp. Developed in the 1960s, they are similar to mercury vapor lamps, but contain additional metal halide compounds in the quartz arc tube, which improve the efficiency and color rendition of the light. The most common metal halide compound used is sodium iodide. Once the arc tube reaches its running temperature, the sodium dissociates from the iodine, adding orange and reds to the lamp's spectrum from the sodium D line as the metal ionizes. As a result, metal-halide lamps have high luminous efficacy of around 75--100 lumens per watt, which is about twice that of mercury vapor lights and 3 to 5 times that of incandescent lights and produce an intense white light. Lamp life is 6,000 to 15,000 hours. As one of the most efficient sources of high CRI white light, metal halides as of 2005 were the fastest growing segment of the lighting industry. They are used for wide area overhead lighting of commercial, industrial, and public spaces, such as parking lots, sports arenas, factories, and retail stores, as well as residential security lighting and automotive headlamps (xenon headlights).
Question: is metal halide the same as mercury vapor

Output: 0


Input: Consider Input: Passage: The Woolpack -- The Woolpack is a fictional public house on the popular ITV soap opera Emmerdale. Its sign is a wool bale, a popular symbol in sheep-rearing country. It has played host to many of the soap's storylines and is the focus of the programme. It is the second oldest TV soap pub, opening its doors in October 1972 and being preceded by The Rovers Return Inn which opened in December 1960 and succeeded by The Queen Victoria which opened in February 1985. The Woolpack is the only soap pub to have changed locations as part of a story-line. In 1976, the original Woolpack was found to be suffering from subsidence. Another building was bought by landlords Amos Brearly and Henry Wilks and made its debut as The Woolpack later the same year. This was to cover Emmerdale Farm's move from Arncliffe to Esholt for location filming.
