Effectiveness of LED Light Bulbs
Lightbulbs are devices used for producing light from electricity mostly for lighting dark areas. There are several types of light bulbs including LED light bulbs and compact fluorescent (CFs) light bulbs.LED light bulbs use LED being 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 diode is a semiconducting chip that is able to produce visible light once electric current pass through it. Compact fluorescent light bulbs utilize fluorescent light bulbs filled with an inert gas argon and a little amount of heavy metal mercury. When an electric current pass through it, the cathode heats up sending out electrons which hit the argon and mercury. Excitement of mercury once hit by electrons makes it produce ultra-violet light that cannot be seen by the naked eyes. The fluorescent lamb is coated with the phosphor which when the UV light passes through it emits visible light. LED light bulbs are therefore considered to be more environmentally friendly alternative as they do not use mercury which is toxic.
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. 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.
When purchasing an LED light bulb, lumen should be considered other than the wattage. Measuring the energy amount a light bulb draws is wattage units while measuring the brightness a light bulb produces is done by lumen units. CFs and LED light bulbs could have the same number of lumens but the wattage of CFs would be higher than that of LEDs. 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, The measurement of color temperature is kelvins and the lower the number, the yellower the 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.
LED light bulbs which are viable for even larger scale lighting have been developed recently and have well and improved efficiency, output, and cost. When installing LED light bulbs, compatibility with fixtures should be checked to avoid excess heat which can lead to failure or fire.
