Text: A 3-way lamp, also known as a tri-light, is a lamp that uses a 3-way light bulb to produce three levels of light in a low-medium-high configuration. A 3-way lamp requires a 3-way bulb and socket, and a 3-way switch. Unlike an incandescent lamp controlled by a dimmer, each of the filaments operates at full voltage, so the color of the light does not change between the three steps of light available. Certain compact fluorescent lamp bulbs are designed to replace 3-way incandescent bulbs, and have an extra contact and circuitry to bring about similar light level. In recent years, LED three way bulbs have become available as well.

Question: can you put a regular light bulb in a 3 way?

Text: The North Pole is the northernmost point on the Earth, lying diametrically opposite the South Pole. It defines geodetic latitude 90 North, as well as the direction of true north. At the North Pole all directions point south; all lines of longitude converge there, so its longitude can be defined as any degree value. Along tight latitude circles, counterclockwise is east and clockwise is west. The North Pole is at the center of the Northern Hemisphere.

Text: The Spanish National Health System (Spanish: Sistema Nacional de Salud, SNS) is the agglomeration of public health services that has existed in Spain since it was established through and structured by the Ley General de Sanidad (the ''General Health Law'') of 1986. Management of these services has been progressively transferred to the distinct autonomous communities of Spain, while some continue to be operated by the National Institute of Health Management (Instituto Nacional de Gestion Sanitaria, INGESA), part of the Ministry of Health and Social Policy (which superseded the Ministry of Health and Consumer Affairs--Ministerio de Sanidad y Consumo--in 2009). The activity of these services is harmonized by the Interterritorial Council of the Spanish National Health Service (Consejo Interterritorial del Servicio Nacional de Salud de Espana, CISNS) in order to give cohesion to the system and to guarantee the rights of citizens throughout Spain.
