Ecologically friendly options for exchanging incandescent lighting are normally either Compact Fluorescent Lamps (CFL) or even the Light Emitting Diode (LED) bulbs.
Solid-state lights, more commonly referred to as LED (light-emitting diode) lighting is a firm semiconductor light source that doesn’t use a gas tube like that of the CFL. There is absolutely no filament to burn out, and distinct CFLs, LED lights are free from the toxic mercury, nor do they release ultraviolet light.
To obtain a bright output, lots of older models of LED light bulbs had resorted to clustering many individual LEDs into one durable housing, however many of the newer LED bulbs drive a single high focused LED element. These LED light bulbs are noticeably smaller than their CFL counterpart, and are accessible in variety of forms that produce a directional beam by means of a glass or plastic lens, or encased behind a frosted diffuser to give larger light coverage.
Summary of Benefits
More cost effective Electricity Bill:
Even if the cost of the light bulbs are at first more expensive, both CFL and LED lamps help to save money in the long run. Less electricity can be used, and bulbs are being substituted much less frequently. LEDs use about half the amount of electricity than CFLs that bring the same brightness capacity.
Long Lifespan:
Run-times of CFL bulbs typically vary from 6,000 hours to 15,000 hours while the average longevity of an incandescent lamp is about 1,000 hours. A LED bulb can last 50,000 to 60,000 hours which means more or less 5 or 6 years (10 times longer than a CFL).
High quality light output:
Both CF and LED bulbs can now supply a range of color temperatures. People are no longer limited to the blueish, “cool-white”, of former bulbs, and can now buy warmer colored lamps. Lower quality CF bulbs that use a magnetic ballast will likely flicker. Choose an electronic ballast when buying a CF. LEDs are driven by electricity or solar energy in order that they don’t flicker.
Versatility:
Indoor, outdoor, residence, or business-related LED and CF bulbs should be considered in many different kinds of uses where conventional bulbs were once used. LED bulbs and CF Ls can be employed in trail lighting, table lamps, task lighting, recessed fixtures, as well as ceiling light fittings. Both types of lights are available in dimmable versions for use with a standard dimmer control key.
Durability:
Since LED light bulbs don’t work with a filament like incandescent, they are shock repellent and can be used in high vibration instruments.
Summary of Disadvantages and Limitations
CF Ls:
Temperature sensitivity – CF Ls are sensitive to heat, their lifetime will be diminished if the fixture does not properly resolve heat. CF Ls are also affected by very cold weather. CF Ls will take considerably longer to attain full brightness in cold weather. In extreme times they may not appropriately warm up.
Harmful waste – CF Ls possess mercury and must be carefully disposed of. The EPA website gives proper disposal tips. LEDs does not contain mercury.
Constant Cycling Lowers Lifespan – In high traffic areas, for instance home bathrooms, where CF Ls are flipped and off from time to time, their longevity will decrease immediately.
Ultraviolet Light – CF bulbs can emit UV-light which may not be appropriate for certain applications.
LEDs:
High early cost – The LED lamps themselves are really expensive, but the initial investment is easily recuperated in decreased electricity bills.
Heat generation – Certain high power (5w or more) LED light bulbs may produce significant heat. Heat-sinks are often built into the bulbs themselves, and may require LED certain fixtures to make sure proper air-flow.
LED light bulbs have become the choice for energy-efficient lighting due to their diverse bulb options, and the ease of which the illumination output could be layered and handled when compared with CF bulbs.
