The interest over LED light bulbs for home usage over the years has been slowly increasing. This is because of the rising electrical cost, which is due to depletion of our environmental resources. So, knowing this, why should we consider using LED light bulbs? What are the benefits for using LED light bulbs at home?
It is no secret that LED light bulbs are efficient, in fact it's the most efficient light source currently available. A conventional LED light bulb easily have a lifespan of 30,000 to 100,000 hours, compared to fluorescent or incandescent which is at 10,000 hours and 2,000 hours. Besides long lifespan, an LED light bulb consumes less electricity than its competitors. For example, using an 18-watt LED to replace a 75-watt incandescent will save about 570 kWh over its lifespan, which translates to an electrical savings of $45 dollars, providing it costs 8 cents per kilowatt. It might not look a lot, but once you multiply it with the amount of light bulbs at your home, then the savings will make much more sense. Although the initial price of LED light bulbs are higher than fluorescent or conventional light bulbs, its long life and electrical savings makes it cheaper over its lifetime.
Mercury is a harmful and toxic substance found in fluorescent or incandescent light bulbs, and in the case of a broken light bulb, you are recommended to treat it as a hazardous material. The presence of mercury in fluorescent or incandescent light bulbs make disposing it difficult. On the other hand, LED light bulbs are safe because it has no mercury at all. Flourescent and incandescent light bulbs operating temperature are capable of reaching up to 180F degrees and 200F degrees, whereas LED light bulbs has such a low operating temperature that you are capable of holding it with your bare hands and this is due to the aluminum heat sink design. The low operating temperature also means that in case of an electrical short-circuit, the chances of fire caused by LED light bulbs are dramatically less. LED light bulbs also doesn't emit UV light, this is good for us cause it prevents cancer and premature aging, not to mention that it won't attract those pesky night bugs.
3. Instant light
It is a common occurrence that when switching on fluorescent or incandescent light bulbs, that there is a slight delay and flickering before it's properly lighted up. LED light bulbs on the other hand lights up instantly and with full illumination. This is a real advantage especially when it comes to area in your home where lights are often switched on and off, such as the bathroom. Sometimes, light bulbs exhibit flickering even during operation, this could give us eye strains, headache and general discomfort. In fact, a research conducted by Lighting Research and Technology in 1989 found out that there is an increase of 50% in eye strain and headaches complains when there is flickering. The good news is LED light bulbs produces a steady light and does not flicker at all.
These are some of the benefits of using LED light bulbs, and with the increasing trend of using LED lights for homes, fixtures and many other applications, the price of a single LED light bulb will become cheaper. In fact as the price continues to go down, this trend is going to grow. It's possible that in the future LED light bulbs will be the most widely used lighting and will be more energy-efficient then what it is today.
