Trubnaya (russian: Тру́бная) is a Moscow Metro station in the Tverskoy District, Central Administrative Okrug, Moscow. It is on the Lyublinsko-Dmitrovskaya Line, between Dostoyevskaya and Sretensky Bulvar stations. Trubnaya opened on 30 August 2007 as a part of the long-awaited line extension northwesternwards. It was a northwestern terminus of the line until June 2010. Name It is named after . Transfer It offers a transfer to the station on the Serpukhovsko-Timiryazevskaya Line. Transfer to Tsvetoy Boulevard station is achieved in a two part process that involves an ascent into an interim hall and then a walk to the older station. History Construction of the station began as far back as 1984, during the building of Tsvetnoy Bulvar station which set provisions for the future station, and during the late 1980s was fully underway with plans to open by the late 1990s. However the dissolution of the Soviet Union in 1991 put a long delay to construction which at time s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fluorescent Lamp
A fluorescent lamp, or fluorescent tube, is a low-pressure mercury-vapor gas-discharge lamp that uses fluorescence to produce visible light. An electric current in the gas excites mercury vapor, which produces short-wave ultraviolet light that then causes a phosphor coating on the inside of the lamp to glow. A fluorescent lamp converts electrical energy into useful light much more efficiently than an incandescent lamp. The typical luminous efficacy of fluorescent lighting systems is 50–100 lumens per watt, several times the efficacy of incandescent bulbs with comparable light output. For comparison, the luminous efficacy of an incandescent bulb may only be 16 lumens per watt. Fluorescent lamp fixtures are more costly than incandescent lamps because, among other things, they require a ballast to regulate current through the lamp, but the initial cost is offset by a much lower running cost. Compact fluorescent lamps are now available in the same popular sizes as incand ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
