Effectiveness of LED Light Bulbs
Lightbulbs are devices used for producing light from electricity mostly for lighting dark areas. LED light bulbs and compact fluorescent (CFs) light bulbs are some of the commonly used light bulbs.LED is used by light bulbs which are solid-state lighting devices that are capable of fitting in standard screw-in connections. The term LED is an abbreviation for light emitting diodes which are employed to produce light in LED light bulbs. The bulbs produce visible light by the use of a semiconductor device every time an electric current pass through it. Compact fluorescent light bulbs use fluorescent lambs that are filled with argon gas and a little bit of mercury. Argon gas and mercury in the fluorescent lamb are hit by negatively charged electrons produced when the cathode is heated. Mercury once excited produces ultra-violet light which is not visible by the human eyes. Visible light is the emitted when the UV light passes through phosphor that coats the fluorescent lamb. Mercury is a heavy metal being utilized by CFs light bulbs and very harmful to the human health hence the CFs light bulbs are not environmentally friendly.
CFs are not energy efficient as compared to LED light bulbs. Led light bulbs start lighting immediately once switched on without requiring time for warming up to generate light. Durability of LED light bulbs is key as they are not made out of glass other they are made of plastics which is highly durable. Thy work quite well in cold weather. CFs light bulbs utilize a lot of energy in lighting and are also not long lasting making them cost ineffective.
Lumen of light bulb should be one of the major consideration other than wattage during purchase of the LED light bulbs. Lumen is the real measurement of the brightness provided by a light bulb while wattage is the measurement of how much energy a light bulb draws. CFs light bulbs draw much more energy than LED light bulbs for the same number of lumens hence LEDs are more energy efficient. Choosing an LED light bulb to purchase requires one to decide the color needed from the wide array of color ranges and where the bulb is to be used, Kelvins are the measurement units for color temperature and a lesser number shows a yellower color. An LED driver is key during purchase of LED light bulbs for converting the alternating current from the power supply to direct current used by the LED light bulbs.
Improved LED light bulbs have been developed with better efficiency, cost and output making them suitable for all environments. Fire may occur or failure of the LED light bulbs when compatibility with fixtures is not checked during installation.
