High-efficient 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 light bulbs are solid-state lighting devices that are capable of fitting in standard screw-in connections and they utilize LED. LEDs are basically light emitting diodes utilized in light bulbs to produce light. The diode is a semiconducting chip that is able to produce visible light once electric current pass through it. Compact fluorescent light bulbs use fluorescent lambs that are filled with argon gas and a little bit of mercury. The cathode in the fluorescent lamps is heated and produces electrons which hit the argon gas and mercury. The excited mercury produces ultraviolet light (UV) which is not visible. The fluorescent lamb is coated with the phosphor which when the UV light passes through it emits visible light. Mercury used in CFs makes them be considered less environmentally friendly since in case mercury spills due to breakage of the fluorescent lamp, it would be toxic to human health.
CFs are not energy efficient as compared to LED light bulbs. The LED light bulbs do not require time for warming up as they start instantly once electricity is switched on. LED light bulbs are made from plastics which makes them more durable than other types of light bulbs made from glass. LED light bulbs are capable of lighting in all weather conditions including cold weather. LED light bulbs minimize on cost as they last longer and use minimum energy as compared to CFs.
Lumen of light bulb should be one of the major consideration other than wattage during purchase of the LED light bulbs. Measurement of the brightness given off by a light bulb is what is referred to as lumen while the wattage is the measurement of the amount of energy a light bulb draws. CFs and LED light bulbs could have the same number of lumens but the wattage of CFs would be higher than that of LEDs. The right color of Led light bulb should be considered since they have a wide color range and where the bulb will be used. The measurement of color temperature is kelvins and the lower the number, the yellower the color. Converting alternating current from power supply to direct current usable by LED light bulbs requires an LED driver.
LED light bulbs which are viable for even larger scale lighting have been developed recently and have well and improved efficiency, output, and cost. LED light bulbs should be checked for compatibility for use in fixtures during installation as heat build-up can cause light bulb failure or even fire.
