Commonly called 'light bulbs', lamps are the removable and replaceable part of a light fixture, which converts electrical energy into electromagnetic radiation. While lamps have traditionally been rated and marketed primarily in terms of their power consumption, expressed in watts, proliferation of lighting technology beyond the incandescent light bulb has eliminated the correspondence of wattage to the amount of light produced. For example, a 60 W incandescent light bulb produces about the same amount of light as a 13 W compact fluorescent lamp. Each of these technologies has a different efficacy in converting electrical energy to visible light. Visible light output is typically measured in lumens. This unit only quantifies the visible radiation, and excludes invisible infrared and ultraviolet light. A wax candle produces on the close order of 13 lumens, a 60 watt incandescent lamp makes around 700 lumens, and a 15-watt compact fluorescent lamp produces about 800 lumens, but actual output varies by specific design. Rating and marketing emphasis is shifting away from wattage and towards lumen output, to give the purchaser a directly applicable basis upon which to select a lamp.
Huge much light does a 13 W compact fluorescent lamp produce equivalent to a incandescent light bulb.

The city's airport was Plymouth City Airport about 4 miles (6 km) north of the city centre. The airport was home to the local airline Air Southwest, which operated flights across the United Kingdom and Ireland. In June 2003, a report by the South West RDA was published looking at the future of aviation in the south-west and the possible closure of airports. It concluded that the best option for the south-west was to close Plymouth City Airport and expand Exeter International Airport and Newquay Cornwall Airport, although it did conclude that this was not the best option for Plymouth. In April 2011, it was announced that the airport would close, which it did on 23 December. However, FlyPlymouth plans to reopen the city airport by 2018, which will provide daily services to various destinations including London.
By what year is the city airport planned to reopen?
2018

Whitehead's idea of God differs from traditional monotheistic notions. Perhaps his most famous and pointed criticism of the Christian conception of God is that "the Church gave unto God the attributes which belonged exclusively to Caesar." Here Whitehead is criticizing Christianity for defining God as primarily a divine king who imposes his will on the world, and whose most important attribute is power. As opposed to the most widely accepted forms of Christianity, Whitehead emphasized an idea of God that he called "the brief Galilean vision of humility":
