Learning The “Secrets” of Lighting

Benefits of LED Light Bulbs.

Devices that generate light from electricity and are quite important in warming dark areas are referred to as light bulbs. 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. 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. 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. The UV light is then passed through a phosphor which causes it to emit more 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.

The energy efficiency of the LED and CFs light bulbs varies considerably with the LED light bulbs being more efficient. 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 and CFs light bulbs have the same lighting conditions although the LEDs last longer as use less energy making them cost effective.

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 light bulbs draw much more energy than LED light bulbs for the same number of lumens hence LEDs are more energy efficient. Other consideration when purchasing a light bulb is the color need since they have a wide color range and also where the bulb is to be used. The measurement of color temperature is kelvins and the lower the number, the yellower the color. LED light bulbs require a direct current electrical power hence LED driver is required to convert the alternating current from the power supply.

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.
