When it comes to energy savings, LED lights certainly have come a long way. LED lights are applauded not only for being energy-efficient compared to traditional incandescent lightning, they are also highly recommended in terms of safety and longer lasting thus making them the preferred lightning choice for residential and commercial establishments.
LED or Light Emitting Diodes are made up of conductors which light up when a series of voltages or electric current pass through them. LEDs are divided into three main categories – miniature, high-powered and customized. Miniatures are single-die LEDs which are further sub-divided into low current, standard and ultra-high output and are commonly used as indicators. The mid-range LEDs are commonly found on automotive tail-lights, light panels and for small emergency devices. High-powered LEDs on the other hand are often used on lamps and semiconductors that make use of hundreds to thousands of lumens.
Differences of LEDs with other Lighting
One of the major differences between LEDs and incandescent or fluorescent lamps is the estimated lifespan of the bulb(s). Incandescent bulbs can last up to 1000 hours of continuous use; halogen lamps on the other hand have an estimated lifespan of 1000 to 5000 hours. CFLs are better as they range from 8000 to 15000 hours. LEDs however can last up to 20 to 40000 hrs lifespan. The reason behind this is that LEDs are 滅蚊燈 made up of several diodes which slowly dim one at a time, unlike incandescent bulbs that have to be replaced entirely once the filament dies out. Another major difference between these bulbs is the light and energy that are emitted. LED emits light in a specific direction which makes it more energy-efficient unlike incandescent bulbs that emits light in all directions. LEDs also radiate little amount of heat thanks to a heat sink that absorbs the heat emitted.
Advantages of Using LED Energy STAR Light Bulbs
One of the best advantages that one would have in installing LED bulbs is that the light output is set at a certain direction enabling one to get the maximum light output unlike other bulb types. LEDs are also environmentally friendly and cost efficient as these last longer than the regular lighting and unlike the traditional light bulbs, emit little heat which prevents damage to sensitive objects or materials.
Although LEDs tend to be more expensive than regular light bulbs, the cost is balanced out by the longer lifespan as well as the quality and efficiency of the lighting source.
