It is estimated that lighting accounts for 18% to 50% of global electricity consumption, depending on the location. Saving energy and reducing your carbon footprint with LED lights can therefore offer a good start to the “green”. LED lamps, in contrast to fluorescent lamp technology, also do not contain mercury, so there is less pollution of the environment. The long lifetime of LEDs also means that less conventional LEDs are produced and destroyed. Conventional lighting options consist of incandescent, fluorescent and compact fluorescent lamps. Compared to these two options, LED lighting provides more lumens, longer life and lower power consumption.
High-quality LED lamps last longer, are more durable and offer comparable or better light quality than other types of lighting. LEDs are the latest and most exciting technological advances in the lighting industry. LEDs are small, solid bulbs that are extremely energy efficient and durable.
LEDs come almost immediately in full brightness (single digits for ten nanoseconds) and have a shutdown time in ten nanoseconds. In contrast, the warm-up time or the time it takes for a lamp to reach full light output can take up to 3 minutes for compact fluorescent lamps. High-intensity discharge lamps require a warm-up time of several minutes before they provide usable light. Hot comfort is a much greater concern than the initial commissioning of metal halide lamps, which were once the main technology for high-bay lighting and high-power floodlights in industrial facilities, stadiums and arenas. A power failure of a plant with metal halide lighting can affect safety, as the hot breaking process for metal halide lamps takes up to 20 minutes. Instant start and warm recovery give LEDs a unique position to effectively perform many tasks.
While the average incandescent bulb can cost half the price of an LED bulb, the same incandescent bulb would cost almost five times as much as an LED bulb every month. This monthly amount, which is added to the consumer’s utility bills, can be slightly reduced by switching to LED. Many people replace square downlight obsolete incandescent, halogen and compact fluorescent lamps with light-emitting diode lamps, but what are the advantages of this change? There are many advantages, including increased energy efficiency, lower utility bills, longer lamp life and a better and generally safer light source.
The ability to change the spectral composition of white light is a huge advantage of LED technology. LED lighting can be used to create any spectral configuration of light that positively contributes to human health and well-being. LEDs have a lifespan of up to 60,000 hours compared to the typical 1,500 hours of incandescent bulbs. A good LED light can be used continuously for more than 7 years before it needs to be replaced.
