Overview
Environmentally pleasant choices for changing incandescent lighting are often both Compact Fluorescent Lamps (CFL) or Light Emitting Diode (LED) bulbs.
Compact Fluorescent Lamps
CFLs function equally to standard fluorescent lamps the place electrical energy is used to activate mercury vapor that resides within the glass tube. The present impacts the mercury atoms to make ultraviolet (UV) light which isn’t seen to the attention. The photons from the ultraviolet light hit a phosphor layer contained in the bulb housing to emit photons of seen light thereby creating light output from the tube. The ultraviolet light might trigger fading in work or textiles. The mercury contained throughout the lamp signifies that the light bulbs must be correctly disposed of as compact fluorescent bulbs dumped in landfills burst, inflicting mercury to be launched, draining into the bottom, finally contaminating the meals chain. Some states, reminiscent of California, ban the disposal of mercury-containing bulbs within the trash. Some state legal guidelines require fluorescent bulbs to be collected as hazardous waste or correctly recycled. Test with the EPA website that can assist you with correct disposal procedures in accordance with your state, or you’ll find a recycling middle close to you at Earth911.
In contrast to fluorescent tubes that do not include circuitry, compact fluorescent often combine all the vital circuits within the backside of the light permitting the one unit for use in a typical incandescent light bulb socket. CFLs are available in quite a lot of types and shapes, however one will usually see them in a tube or spiral possibility.

LED Lighting
Stable-state lighting, extra generally referred to as LED (light-emitting diode) lighting is a stable semiconductor light supply that does not use a fuel tube like that of the CFL. Light from an LED is made when electrical energy is utilized by way of the semi-conductor doped with impurities to create one half which is a “p-side”, and one other half that kinds the “n-side”. The charge-carriers (electrons and holes) stream into the p-n junction the place these two halves meet, and releases power within the type of a photon, thereby creating light. The colour of the light output will depend on the supplies forming the p-n junction. There is no such thing as a filament to burn out, and in contrast to CFLs, LED lights don’t include the poisonous mercury, nor do they emit ultraviolet light.
To get a brilliant output, many older fashions of LED light bulbs had resorted to clustering many particular person LEDs right into a one housing, nevertheless lots of the newer LED bulbs drive a single excessive powered LED aspect. These LED light bulbs are significantly smaller than their CFL counterparts, and are provided in kind components that produce a directional beam by way of the usage of a glass or plastic lens, or encased behind a frosted diffuser to supply wider light protection.
