They offer the most benefits and features – as well as the fewest drawbacks – of any light bulb.Lumens Are the New Unit of Measurement for Light Bulbsįor decades, we've been buying light bulbs according to their brightness measured in watts. While personal preference accounts for a lot and can have a major impact on what bulb you ultimately select, LEDs are unquestionably the best choice you can make. + Capable of supporting greenhouse production + Coloured and colour changing bulbs (light) Must be recycled at a proper recycling site.To learn more about LEDs and how they work, check out our guide.ĬOMPARE: A Single 700 Lumen Light Bulb Operating 8 Hours/Day They were met with hesitance at first because of their cool colours and unusual shape, but LEDs have since become a superior technology and now boast a number of benefits you won’t find in other bulbs.Įxtremely efficient, long-lasting, and capable of replicating a number of colours and colour temperatures, LEDs are an environmentally-friendly option that should be at the top of your list when looking for light bulbs. Now that the technology is better understood, LEDs are quickly overtaking their predecessors in terms of popularity. This resulted in the invention of white LEDs suitable for use in light bulbs, which first became available commercially in 2002. The first LEDs were green, but in the mid-90s, high-brightness blue LEDs were introduced. LEDs have been in the works for a long time – since the early 1900s! It took over a hundred years and a number of inventors, engineers and innovators for a commercially viable LED bulb to hit the shelves. However, there are some drawbacks to keep in mind:Īn LED is a type of diode that emits photons as light instead of heat. Slow warm-up times and cool colour temperatures made the adoption of this type of bulb slow and sporadic, but they have greatly improved over the years and are now available in warmer colours, dimmable options, and with faster warm-up times.ĬFLs are more durable, longer lasting and more energy-efficient than incandescent and halogens, making them a viable alternative for replacing your bulbs without breaking the bank. In spite of their improved efficiency and lower operating costs, CFLs didn’t hit the ground running. The current reacts with the gas and produces ultraviolet light, which becomes visible light as it passes through the phosphor coating. Instead of relying on a filament, these bulbs operate like fluorescent tubes: two ballasts on either end conduct an electric current through the tubes, which are filled with gas and lined with a phosphor coating. They work the same way as standard incandescents, but use less energy and last longer because they contain halogen gas, which helps extend the life of the tungsten filament.Ĭompact fluorescent bulbs were the first contender for replacing incandescent bulbs. Halogen bulbs are a type of incandescent bulb. Shop our full selection of incandescents. This is because these bulbs have not yet been adequately replaced by newer technologies. Most incandescent bulbs you find now will be specialty bulbs, such as candle and other decorative bulbs, or rough service bulbs designed to withstand use in appliances. So, if your heart is set on incandescent, now’s the time to stock up. The good news is that incandescent bulbs have not yet been outright banned, and they are still available to purchase while supplies last. In spite of its inefficiencies, this bulb is much beloved by those who are finding it difficult to part with the classic shape, colour and glow of the original light bulb. Phasing out special purpose incandescentsĭirectional mains-voltage halogen bulbs (ex. Remaining clear incandescent bulbs under 60W As a result, governments around the world have been phasing them out, and many manufacturers have already stopped producing them, making them difficult to come by much earlier than their mandated phase-out dates: Incandescent Phase-out Timelineįrosted finish bulbs that don’t have an A energy rating That’s why these bulbs get hot to the touch and should not be handled or placed near flammable items until they’ve had time to cool.Ĭompared to other bulbs, incandescents are inefficient and easy to break. They’re called “incandescent” because they use a filament, usually made of tungsten, that is heated by electricity until it becomes incandescent (glowing). Incandescents are the most recognizable and most prevalent light bulbs, and are the type you probably had in your home growing up.
