A light-emitting diode, or LED, is a type of lighting that works substantially differently than a standard light bulb. A diode is an electrical component with two terminals that conducts electricity in one direction only. When an electric current is passed through the component, the diode gives off a bright light. By incorporating many of these diodes onto a pcb (printed circuit board) we obtain stunning uniform light with unmatched light quality and at very minimal energy costs. Another great thing about LEDs is that they can produce a wide range of colors easily and brightly making them a very versatile light source for many applications, such as mood lighting, commercial use, and more.
LEDs are more efficient than other lighting sources on the market, while traditional incandescent or halogen lamps convert most of the electricity used into heat rather than light.
They are fully dimmable but make sure you check the specs before buying as you will need to buy dimmable lights as opposed to standard LEDs. Not all dimmable LED lights are compatible with the old dimmer switch, so again check the dimmer switch you have and whether it will be compatible with your new light. Most LEDs are designed for trailing edge dimmers that can be set to the desired cutoff point to avoid flickering, they are easy enough to set up so nothing to worry about. As LED lighting becomes more common in households, we will see more dimming control options come to market.
The biggest complaint for homeowners using LEDs is the cost, but as demand increases, the cost will drop drastically as can be seen in most online retail stores. The thought of spending tens of dollars/pounds to replace an LED bulb keeps many consumers from buying it, but the reduced energy use and longevity make it a very wise choice for your investment and with a payback period of less than a year you can see. why.
LED bulbs or downlights come in a variety of shapes and sizes with many popular household lights including the GU10 LED lamp, Edison E27 screw lamp and more, these lamps last an average of 25 times longer and use approximately 85 percent less energy than traditional incandescent lamp. bulb (not bad huh). LEDs also last longer than popular compact fluorescent lamps (CFLs) and require no warm-up time, providing instant full light output.
So how do the LEDs compare when measuring their output? As you may have noticed while shopping or online that most lamp packaging has an image quoting ‘Lumens’. Lumen is simply a convenient unit of light output that can be accurately compared to other light sources whereas watts are not a useful measure of light output. As mentioned above, most traditional lamps convert the used electricity into heat which in turn consumes a large part of the lamp wattage and does not result in any usage until its final output. The LEDs produce enough lumens to replace a standard 40 or 60 watt light bulb. And they only use about 9 to 12 watts. So, if you want to replace a single 60 watt bulb, look for an LED bulb with around 800 lumens; for a 40 watt bulb, look for 450 lumens.
So there are many benefits to using LED bulbs over traditional CFLs or incandescent light bulbs. They use less energy and last longer, costs drop quickly and light quality is far superior. And one big advantage that hasn’t been mentioned is the cost to the environment, obviously by reducing your carbon footprint you save on CO2 emissions which in the end is a big deciding factor for many green consumers.
