Light-emitting diodes, or LED’s, are a kind of lighting that works significantly different from a standard light bulb. The diode is an electrical part with two terminals that conduct electricity in one direction only. When an electrical current is passed by the part, the diode gives off a bright light. By combining many of these diodes to a pcb (printed circuit board) we get an amazing uniform light with an unparalleled light quality and at a very minimal energy cost. One other great thing about LEDs is that they can produce a variety of colours easily and brightly making them an extremely versatile light source for many applications, such as mood lighting, commercial use and many more.
LEDs are more efficient than any other lighting source on the market, while the traditional incandescent lamp or halogen lamp transform most of the electricity used to heat instead of light.
They are fully dimmable but please make sure you check the specification before you buy as you will need to buy a dimmable lamp as opposed to a standard LED. Not all dimmable LED lamps are compatible with older dimmer switches so again please check which dimmer switch you have and whether it will be compatible with your new lamps. Most LEDs are designed for trailing edge dimmers which can be setup to a desired cutoff point to avoid lamp flicker, they are pretty easy to setup so should not cause much concern. As LED lighting becomes more shared in households, we will see a greater choice of dimming controls come to market. The biggest complaint for homeowners that use LEDs is the cost of them, but as need picks up the cost will drop dramatically as can be seen on most online retail stores. The thought of spending tens of dollars/pounds to replace LED lightbulbs wards off many consumers from buying them but the reduction in energy usage and long lifespan make them a very wise choice on your investment and with payback times in less than a year you can see why.
LED lightbulbs or downlight’s come in a variety of shapes and sizes with many popular household lamps including the GU10 LED identify, E27 Edison screw lamp and many more, they last on average of 25 times longer and use about 85 percent less energy than traditional incandescent light bulbs (not bad yeah). LEDs also outlast the popular compact fluorescent lamp (CFL) and require no warm up time, giving off the complete light output immediately.
So how do LEDs compare when measuring their output? As you may have already noticed while out shopping or online that most lamp packaging has a figure on it quoting ‘Lumens’. Lumens are just a functional unit of light output that can be precisely compared to other light supplies while wattage is not a useful measure of light output. As mentioned above most traditional lamps transform the electricity used to heat which in turn is using up most of the wattage of the lamp and not producing any use to the end consequence. LEDs produce enough lumens to replace a standard 40 or 60-watt lightbulb. And they only use about 9 to 12 watts instead. So, if you want to replace one 60-watt lightbulb, look for an LED lightbulb with about 800 lumens; for a 40-watt bulb, look for 450 lumens.
So there are many benefits to using LED lighting over traditional CFL or incandescent lightbulbs. They use less energy and last longer, the costs are dropping rapidly and the light quality is far superior. And one enormous advantage that hasn’t been mentioned however is the cost to the ecosystem, clearly with a reduction in your carbon footprint you’re saving on CO2 emissions which ultimately is a big deciding factor for many of environmentally friendly consumers.
So what are you waiting for, make the change today and start saving.
