How to replace 40W fluorescent with 15W LED tube light T8

The calculation that 15W LED tube light T8 replace 40W fluorescent

We already know that:

1, ordinary fluorescent tubes emit the light in all directions, wasting nearly 50% of luminous flux, while the LED tube light emit light at 120 degree light, only 60% of the the fluorescent lamps using the Lamp panel actually to reflect effect is valid, the rest are wastage.

2, there is theoretically no light decay in three years for the LED tube light, there is mostly up to 70% light decay in five years,, and light decay of the ordinary fluorescent reaches about 80% in three years, which is that 20% of the flux lost.

3, the actual wattage of 40 W is 36W fluorescent instead of the standard 40-watt, we collectively call that the 36W fluorescent lamp is 40W

4, the light efficiency of the fluorescent tube is generally 60 ~ 70Lm / W, but many lamps are actually not. Here we take the 80LM / W for example.

So we get the following conclusions:

LED 15W * 80LM / W = 1200LM (Luminous Flux)

LED 15W * 90LM / W = 1350LM (Luminous Flux)

LED 15W * 100LM / W = 1500LM (Luminous Flux)

Fluorescent 36W * 80LM / W = 2880LM 2880LM * 60% (light loss) = 1728LM      1728LM * 80% (lumen) = 1382LM (actual flux)

the overall brightness of 36W fluorescent lamp is actually 1382LM

Several formulas can be seen from the above, what is completely satisfied that 15W LED tube instead of T8 40W ordinary fluorescent lamp, let alone LED tube light that is of 100LM / W high light efficiency.

Nowadays,the LED flood lamps and LED tube light are the most widely used as the representatives of the decorative lighting and the home lighting in daily life,the LED tube light enjoys a great popularity in our corridor, restaurants, shopping, leisure and entertainment, galleries, exhibition halls and other indoor environments everywhere, the LED flood lamps is mainly used in city squares, parks, stadiums, the facades of large commercial buildings and hotel, stage, waiting rooms, airports etc. where the higher brightness is needed to illuminate,meanwhile,there a large number of factory engaging in developing and producing the LED light,Lead Lighting is just one of them,which adopts high brightness SMD as the light source of the LED tube and highly integrated and high brightness COB as the light source of the LED flood lamps so that fully guaranteed stable and soft light of the LED tube light and octahedron breadth and brightness irradiation range of the LED floodlight, while low voltage constant current driver ensure the AC can be converted into the DC to improve energy efficiency of the LED tube light and LED flood lamps and reduce the waste heat energy and stroboscopic effect exciting the human eye, the most important is that the LED lighting without adding mercury and other heavy metals harmful to our body and pollution the environment, that’s why the LED light is Known as energy-saving and environmental protection. Login http://www.ledclan.com to learn more features and uses of the LED tube light and surf www.lead-lighting.com  to know more awesome LED floodlights and other LED lighting.

London street light ”tell ” the Chanel love story

In London, if you want to see the “Chanel ” ,it is not necessarily to enter the upscale department store , walking in the streets as you can do so,which is a “secret” all the Londoner has known, in fact, the symbol is carved on the lamppost of the streets light in the center city.

Infatuated Duke commemorated the love

In front of Big Ben and flowering Regent Park , on the both side of the Europe’s most bustling commercial street Regent Street , the anti-rust black paint is painted on the surface of the high copper lamppost year after year , so that the street lights of the central London have seemed to be great sense of history,the symbol ( as shown ) that is the same as the premium luxury brand “Chanel “has been inscribed with gold paint as color and black as the bottom on lamppost base. This is not the “Crash ” of the London Municipal Design and French luxury goods company’s design, but the genuine “Chanel ” logo both countries have recognized .

Many Britons believe that “Chanel ” that is engraved on the streets lights in the London street originated the founder of the French luxury brand of the same name , which is a section of a exotic romance from the masters of the London City – the Duke of Westminster. In 1925 , Chanel met the Duke of Westminster- Hugh Richard Arthur Gross Wiener in a social gathering of Monte Carlo. The Duke loved the female designers from the French at first sight, the two lovers have to keep five or six years time , Chanel ultimately refused to marry the Duke , but the world is not known what the reason is.

The British Duke who had never been able to forget Chanel decided to engraved “Chanel ” brand logo on the light lamppost of London central street from then on, while uppercase W was engraved next to the mark, on behalf of the Duke of Westminster family . This was done because the silly Duke wanted to tell future generations ” there will be many generations of the Duke of Westminster in the future , but only one Chanel .”

Chanel

Love story on the street in London

“Love Memories” is probably apocryphal

Over the past century , the old city center of London experienced a number of alterations , but the unique symbol representing the two Lover have still been engraved on the new street lights erected. Why is the Duke of Westminster could not discuss with the City of London and make such a decision on the design of municipal facilities? Every Londoner can tell you the answer : Because the Gros Wiener family had been the largest of the ” landlord” in the city ​​of London , including the government district of Westminster and many hinterland gold zone in London are the private property of the Duke family , and which are ” rent not sell .” over the years.

Even the British Prime Minister did not dare manage what the “landlord” would like to do in London . But there are some people doubting the “Chanel ” logo everywhere on the streets of London is really witnessed the part of the love last century? Westminster Government’s transport affairs officer Martin Rolle told reporters that someone will ask the question about this flag meaning almost every year. Although he would not disappointed , but had repeatedly clarified that the signs pieced together by the two letters “C” on the lamppost stands for ” CITY COUNCIL “, more convincing is that these lamp posts hadn’t actually emerged only until the 1950s on the streets of London , which is 20 years latter than when the infatuation Duke met Chanel.

French people love to buy souvenirs lamppost

Although the local government reasoned explanation , but most people are unwilling to accept this answer sounds ” disappointing ” in London. Many locals and reporters who talk about this issue , are convinced that ” two C-word is love sign .” Their view is that how the two Reverse C were staggered and carved together by the government that have always been really given to indicate that this is ” public property ” ? Also said that many of urban area of London are private property of Gros Wiener family until now, if the government did such a lamppost design , it is not impossible to raise the Duke family the design.

Whether love story is true or false , it has become one of discussion people keen to talk  in the London city tours. In the Capitol , where tourists is rushing near Buckingham Palace, the local gold paint exceptionally fast signs off on the lamppost, reportedly because too many tourists touch.

Originally, ” Big Ben ” ” royal red mailbox ” or ” black taxi ” anda variety of knick-knacks often only be bought in the souvenirs shop of London, but now many places are selling “Chanel lamppost “, and some of the vendors told reporters that many of customers are French, they said that they prefer to take the unique view of London and the love story we do not know the true and false together back to France.

Chanel engraved on the lamppost of London leads to romance and tourist hot, which also reflects that the street lights is the city ‘s indispensable municipal facility in London, and the street lights not only provide lighting, while also because of inscribed Chanel attract people’s attention , however , more street lighting facility is to convenient people to travel and decorate the city , along with we have been greater emphasis on the city’s beauty and energy saving, more and more cities started using LED road lights such as LED street light and LED tunnel light,

Meanwhile,there are a large number of manufacturers specializing in developing and producing LED road light over the world, lead lighting is one of them,Lead lighting has been continuing to strengthen the use of certified raw materials such as  LED chips, LED drivers, heat sinks, shell, etc., and improve R & D and production team, striving to adopt the best materials and technology to produce best quality LED flood light, LED tunnel light,LED street light, LED tube light and other indoor and outdoor lighting, using highly integrated high-brightness COB as the light source of the  LED Flood light and LED tunnel light and other outdoor lighting,adopting high brightness SMD LED as the light source of the LED tube light, the low-voltage constant current driver ensure the alternating current can be convert into direct current so that improve the energy use and reduces the stroboscopic effect stimulating the human eye, fully guarantee octahedron illuminated area of LED flood lights and bright light to adapt to outdoor open environment ,the soft and bright light of the LED tunnel light and LED street light and LED tube light makes us safe driving in tunnels and enjoy work and study.As an ISO 9001:2000-certified factory,the lead lighting can meet the strict standards of CE, RoHS, FCC certificate, these strict producing standards guarantee our products distribute smoothly both in domestic and international markets.Visit http://www.ledclan.com to Learn more vivid and specific characteristics of the LED tube light or click http://www.lead-lighting.com/products/bid32-1.htm  for more detailed and professional features and uses of the LED tunnel light or return the homepage to know about  more affordable and qualify LED light.
