About this deal

Like all great inventions, the light bulb can’t be credited to one inventor. It was a series of small improvements on the ideas of previous inventors that have led to the light bulbs we use in our homes today. Incandescent Bulbs Light the Way Both Thomas Edison and Nikola Tesla experimented with fluorescent lamps in the 1890s, but neither ever commercially produced them. Instead, it was Peter Cooper Hewitt’s breakthrough in the early 1900s that became one of the precursors to the fluorescent lamp. Hewitt created a blue-green light by passing an electric current through mercury vapor and incorporating a ballast (a device connected to the light bulb that regulates the flow of current through the tube). While the Cooper Hewitt lamps were more efficient than incandescent bulbs, they had few suitable uses because of the color of the light.

modern kitchen lighting, these characterful light bulbs become a design statement in their own right while providing a cosy ambience and plenty of functional illumination. Energy Saving LED Filament Edison Bulbs There are long life versions of both the SON-E and SON-T lamps, giving over twice the standard lamp life, at up to 55,000 hours. One of the fastest developing lighting technologies today is the light-emitting diode (or LED). A type of solid-state lighting, LEDs use a semiconductor to convert electricity into light, are often small in area (less than 1 square millimeter) and emit light in a specific direction, reducing the need for reflectors and diffusers that can trap light. Although industrial lighting sounds like everything would look at home in a factory, there are plenty of other elements that can count as industrial. Of course, for edgier interior décor styles such as steampunk, industrial style lighting is absolutely perfect, since it plays to the retro-futuristic elements that many writers and artists imagine for the style. But it isn’t just tougher stylings that can benefit from industrial lighting. Nautical inspired rooms look great with lighting that features ropes, mesh, or chains, for example, and tripod lamps that are inspired by photography lighting can work in rooms that are inspired by Scandinavian décor styles.

What are the key facts?

Historical footnote: One can’t talk about the history of the light bulb without mentioning William Sawyer and Albon Man, who received a U.S. patent for the incandescent lamp, and Joseph Swan, who patented his light bulb in England. There was debate on whether Edison’s light bulb patents infringed on these other inventors’ patents. Eventually Edison’s U.S. lighting company merged with the Thomson-Houston Electric Company -- the company making incandescent bulbs under the Sawyer-Man patent -- to form General Electric, and Edison’s English lighting company merged with Joseph Swan’s company to form Ediswan in England.) There are a wide range of industrial lighting options too, including ceiling lights, floor and table lamps, wall lights, pendants, and even chandelier styles. You can find industrial lighting options to suit almost every room in the home, offering a little toughness to contrast with softer interior décor styles. How tough you want your lighting to look is up to you, and there are industrial lights made from all kinds of materials – metals and woods of course, but glass and plastics feature heavily too. Finding texture is definitely not an issue despite fabric not featuring much, as mesh, glass, exposed wires, and even rust finishes provide plenty of contrast. Long before Thomas Edison patented -- first in 1879 and then a year later in 1880 -- and began commercializing his incandescent light bulb, British inventors were demonstrating that electric light was possible with the arc lamp. In 1835, the first constant electric light was demonstrated, and for the next 40 years, scientists around the world worked on the incandescent lamp, tinkering with the filament (the part of the bulb that produces light when heated by an electrical current) and the bulb’s atmosphere (whether air is vacuumed out of the bulb or it is filled with an inert gas to prevent the filament from oxidizing and burning out). These early bulbs had extremely short lifespans, were too expensive to produce or used too much energy.

Also called luminous efficacy, a light bulb’s efficiency is a measure of emitted light (lumens) divided by power it draws (watts). A bulb that is 100 percent efficient at converting energy into light would have an efficacy of 683 lm/W. To put this in context, a 60- to 100-watt incandescent bulb has an efficacy of 15 lm/W, an equivalent CFL has an efficacy of 73 lm/W, and current LED-based replacement bulbs on the market range from 70-120 lm/W with an average efficacy of 85 lm/W.White-Lux are also available in elliptical and tubular, Mercury MBF-U is elliptical, whereas the Dual SON & Mercury, White SON [SDW-T] and SOX lamps are all single ended with either a screw or two pin fitting. Selection of Wattages The metal halide and ceramic metal halide light bulbs come in various fittings, including single and double ended, elliptical and tubular. SON-E lamps are elliptical, SON-T lamps are tubular. While Edison was working on the whole lighting system, other inventors were continuing to make small advances, improving the filament manufacturing process and the efficiency of the bulb. The next big change in the incandescent bulb came with the invention of the tungsten filament by European inventors in 1904. These new tungsten filament bulbs lasted longer and had a brighter light compared to the carbon filament bulbs. In 1913, Irving Langmuir figured out that placing an inert gas like nitrogen inside the bulb doubled its efficiency. Scientists continued to make improvements over the next 40 years that reduced the cost and increased the efficiency of the incandescent bulb. But by the 1950s, researchers still had only figured out how to convert about 10 percent of the energy the incandescent bulb used into light and began to focus their energy on other lighting solutions. Energy Shortages Lead to Fluorescent Breakthroughs

Vintage Edison light bulbs feature a loosely coiled filament that offers a unique and stand-out design, allowing you to take your lighting to the next level. Our retro LED bulbs are available in various shapes, including; Pear, Classic, Globe, Small Globe, Cylinder and Tube in three different glass finishes; amber, smoke grey and clear. Industrial style lighting is exactly what it sounds like – lighting that is inspired by historic industrial designs that used to prioritise function and brightness to facilitate working conditions, rather than looking pretty. That was before designers realised that actually, some industrial lighting options are actually very attractive, and today there are plenty of ways to bring industrial lighting into the home. Energy efficient, reliable, long-lasting as well as incredibly stylish, there is no better option than a vintage Edison bulb. With a statement design, filament bulbs cast a soft, warm glow into any space. Vintage light bulbs aren’t only for industrial and retro-inspired interiors; they work beautifully with modern, contemporary spaces, adding a new layer of charm. Retro Light Bulbs To Add Character

Industrial lights are as flexible as you need them to be for your home too. With modern LED, dimmable technology, or by using a smart bulb, you can set the brightness and tone of your industrial lamp to the perfect level that you need, whether you’re relaxing, or are preparing for another busy day. The range of wattages of our industrial and commercial lamps goes from 70 watts to 400 watts, to suit a variety of uses. Long Life Versions By the late 1920s and early 1930s, European researchers were doing experiments with neon tubes coated with phosphors (a material that absorbs ultraviolet light and converts the invisible light into useful white light). These findings sparked fluorescent lamp research programs in the U.S., and by the mid and late 1930s, American lighting companies were demonstrating fluorescent lights to the U.S. Navy and at the 1939 New York World’s Fair. These lights lasted longer and were about three times more efficient than incandescent bulbs. The need for energy-efficient lighting American war plants led to the rapid adoption of fluorescents, and by 1951, more light in the U.S. was being produced by linear fluorescent lamps. More than 150 years ago, inventors began working on a bright idea that would have a dramatic impact on how we use energy in our homes and offices. This invention changed the way we design buildings, increased the length of the average workday and jumpstarted new businesses. It also led to new energy breakthroughs -- from power plants and electric transmission lines to home appliances and electric motors.
