LED light bulb is the solid-state lamp, which uses the light-emitting diode for the light source. The diode uses the direct current as electric power, which comes through the rectifier circuit from the alternative current (AC). The LED bulb is durable and eco friendly as comparing to the incandescent and fluorescent lamp. The LED bulb may use everywhere and in every occasion because it is the energy efficient, and it has long life. The LED bulb may be used in cosmetic therapy, which heals the wounds and control aging by LED therapy.
Let us discuss the seven reasons why to switch to LED light bulbs.
A LED bulb has a long lifespan of 50,000 hours, which means that if you use the LED bulb continuously five hours daily, then it will last near about 27 years. An investment will give you long monetary benefit for your lighting purpose. The lifespan of a LED bulb depends on the quality of heat sink and capacitor. The fins of the heat sink should be perfect as far as possible because it may circulate the airflow efficiently. Even the capacitors should be made of ceramics, which will increase its life expectancy. Due to various types of shapes and colors, the lifespan of the LED bulb will be different. The white LED bulb has the maximum lifespan, whereas the blue of other colors has fewer life expectancy.
2. Energy efficient
Generally LED bulb uses 2-17 watts of electricity. It will help to reduce the cost of electricity bill. The effectiveness of energy efficiency is more visible in home lighting. Because most of LED bulbs emits white light, which is the photometric output but not radiometric. The white LED bulb has the maximum energy efficiency. The LED bulbs can be focused, which means you do not need to use any reflector. It will reduce the cost of the same light beam. The LED bulb is an excellent dimmer because it never loses its color and in dim condition, it retains its true colors.
3. No mercury
The LED bulb is mercury free. As it does not have any mercury substance, it is an environment friendly. Mercury is very much toxic and harmful to the human body. So the LED bulb prevents the human body from the mercury poisoning which may be possible due to the use of incandescent bulb. Acute exposure to mercury may develop the central nervous system malfunctioning, delirium, hallucinations and suicidal tendency. It may develop fatigue, irritability, loss of memory, vivid dreams and depression.
4. Cooler heating
The temperature of LED bulb is relatively cool as compared to the fluorescent or incandescent bulb. The fluorescent lamp’s temperature may reach up to 180 F, whereas the incandescent lamp may reach up to 200 F. The heat from the LED bulb builds the surrounding environment relatively cool and friendly. The LED bulb light also increases the concentration level by emitting a cooler light beam. It is suitable for the kids. The cooler lighting always builds up a sound living atmosphere in home. The LED bulb prevents us from the excessive heat pollution in the indoor environment.
5. UV emission free
The LED bulbs never emit any UV radiation. Ultraviolet radiation is invisible to human eye. The ultraviolet radiation range varies from 10 nm to 400 nm. The ultraviolet range which is less than 300 nm is invisible to human but if the UV range is more than 400 nm, then it is visible to human eye. Actually, UV radiation is available in the incandescent and fluorescent lamp. UV radiation may cause skin cancer, eyestrain or headaches. It also causes the premature aging.
6. Hum free
The LED bulb is hum free, which means it does not emit any droning sound. This humming sound, which emits from the fluorescent bulb, is very much irritating. This noise pollution causes hyperactivity, fatigue and attention deficits. The hum is the low frequency (50 or 60 Hz) noise, which may develop bad effect on the human body. The constant hum sound may hamper the concentration power, particularly in children.
7. Flicker free
The LED bulb is flickers free. It emits flicker in very negligible proportion. Actually, it emits no flicker. Generally, if you live with the flickered light beam continuously, then it may develop motion sickness, dizziness and headaches. Sometime in the extreme case, you may develop nausea. Generally, the LED bulb emits 40-50 kHz frame rate, which is very much negligible to human eye. Therefore, you will get the flicker-free light from LED bulb.
So now, you have ample reasons to switch over to the LED light bulbs from the incandescent or fluorescent lamp without any doubts.
