A prelit tree is a convergent product of Christmas lights and an artificial Christmas tree. The product is an artificial fir tree that comes pre-wired and strung with lights, which cannot be removed and are usually embedded within the artificial branches. The product can be sold as a kit - the user assembles the tree and plugs it into an electrical outlet - or the dealer may assemble it before the sale. Prelit trees may have traditional mini bulb lights, LED lights, or fiber-optic lights. Larger trees usually contain traditional strands of bulb lights while smaller tabletop trees have fiber optic branches. Some more expensive trees come with energy-efficient LED lights. Prelit trees are being classified into the categories of electrical products. ==History== The first lighted Christmas trees made use of candles. Attaching the candles was a difficult process, and proved to be a fire hazard. The tree could not be left unattended when the candles were lit. A bucket of water also had to be kept near the tree and someone had to keep watch for a possible fire. Candle wax was expensive, so later trees used lamps that were made from nutshell halves filled with oil and a wick. More elegant lamps were made from different colours of glass. The new candle holder, called a counterbalance candle holder, had a weight attached to the bottom that kept the candle standing upright. However, even with these improvements, the trees still proved to be fire hazards. The invention of the electric light added a new dimension to Christmas trees. In 1882 an inventor named Edward Hibberd Johnson working for Thomas Edison devised a way of wrapping small electric lights in red, white, and blue crêpe paper. These coloured lights that were strung on a tree provided the earliest version of contemporary Christmas lights. However, Christmas tree lights were still experimental throughout the 1880s. Miniature Christmas lights were first developed in 1895 by Ralph E. Morris, an employee of the New England Telephone Company. Morris’ idea for miniature Christmas lights occurred as he was looking at the tiny bulbs on telephone switchboards. However, many Americans still distrusted the safety of electric lights throughout the early 1900s and candles were still used to illuminate trees. The early Christmas tree lights were simply night-lights strung together to form light strings. When General Electric commercially introduced Christmas lights, they quickly became popular. 〔(【引用サイトリンク】url=http://www.history.com/topics/christmas/history-of-christmas/videos/christmas-light-technology )〕 〔 Edison Electric soon followed suit with an electric Christmas lamp. In the early 1990s the world's largest artificial Christmas tree maker, Boto Company (bankrupted in January 2008) started the first production of prelit trees supplied to Target stores. Recent technical advances in the manufacturing process of prelit trees has made them easy to assemble and realistic looking. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Pre-lit tree」の詳細全文を読む スポンサード リンク
