Power Efficiency Guide

LED or Light Emitting Diode Power Efficiency Guide Review lights are solid state lighting units that are made up of a grouping of smaller units, operating using a semiconductor diode that produces an 'electroluminescence' effect to create the light. Although LEDs were invented in the 1920s they weren't really produced in a practical form until the early 1960s. LED spotlights can provide a great alternative to halogen lamps. Higher wattage versions of LED spotlights e.g. 3 watt, can be used for normal area lighting, and even lower wattage (2 watt) can be used for accent lighting. If you haven't really thought about using Led lights, or know little about them, her are a number of great reasons for using them for your home, business, or even vehicles. As previously mentioned, these lights don't use heated filaments, or gas and filament combinations to create light, and unlike incandescent bulbs they don't produce much heat at all. This gives their application even wider scope, and it means that LED spotlights for instance aren't likely to damage precious / delicate items and surface they're placed next to. Also, LEDs don't contain / give off toxins e.g. mercury, which is good for us and our environment. Perhaps their greatest and most prominent feature is their ability to save energy and keep doing so over a much longer period than incandescent bulbs. Most of us are used to buying (relative short life cycle) incandescent bulbs which seem cheap to purchase. Although LED lights have a higher purchase price due to the expensive sapphire substrate used in their production, their life cycle is likely to be 50 times longer! If you think of how much it is to purchase them with that in mind, you'll see that they may actually work out to be cheaper. LEDs have a much higher efficacy than incandescent bulbs - they produce more light relative to the amount of energy used to produce it - this makes them a highly efficient source of light. For example, because they produce more lumens per watt, a 13 watt LED lamp will produce the same lumen value as a 40 watt incandescent bulb, the implication is that less power is needed to do the same job, thus LEDs are ENERGY SAVING - your electricity bills could be lowered by using them. Environmentally their energy saving properties also translate to less CO2 being produced to run Led lamps compared with incandescent bulbs. Using the 13 watt LED and 40 watt incandescent example again, the LED lamp could produce one third less CO2. Just think of the reduction in carbon footprints of homes and offices if LED lamps were used to replace other types of bulbs and lamps.
