Effectiveness of LED Light Bulbs
Devices that generate light from electricity and are quite important in warming dark areas are referred to as light bulbs. There are several types of light bulbs including LED light bulbs and compact fluorescent (CFs) light bulbs.LED light bulbs are solid-state lighting devices that are capable of fitting in standard screw-in connections and they utilize LED. Light emitting diodes is the short form for LED used to generate light in bulbs. The bulbs produce visible light by the use of a semiconductor device every time an electric current pass through it. Fluorescent bulbs filled with argon gas and a small amount of mercury are employed for use in compact fluorescent light bulbs. 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. Visible light is the emitted when the UV light passes through phosphor that coats the fluorescent lamb. 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.
The energy efficiency of the LED and CFs light bulbs varies considerably with the LED light bulbs being more efficient. 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. Cold weather is not a limiting factor of LED light bulbs to work properly. 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. 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. 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. Converting alternating current from power supply to direct current usable by LED light bulbs requires an LED driver.
LED light bulbs have been recently improving with much better efficiencies, outputs and cost hence can be used in all environments. Fire may occur or failure of the LED light bulbs when compatibility with fixtures is not checked during installation.
