LED Light Bulbs for Home Use

LED Light Bulb for Home UseLED (Light Emitting Diode) bulbs are economical to operate and environmentally friendly.  An LED bulb can replace an incandescent or a CFL bulb with a screw-in style base.  These lights are more efficient than other types of lights and the bulbs can last to last 20 to 30 years depending on the type of use. Unlike CFL’s, they do not contain mercury and turning the lights on and off does not degrade their useful life.  For home applications, LED’s can be used as light bulbs in desk lamps, track lighting outdoors and tube lighting in kitchens and bathrooms.

Advantages of LED bulbs

LED bulbs are more energy efficient than fluorescent bulbs and incandescent bulbs.  So they are better for the environment and for your electricity bills.  To get an idea of how much energy you can save, the following table shows approximately how many watts are consumed for an incandescent bulb, a compact fluorescent bulb, and an LED bulb.

Incandescent Bulb Watts           CFL Bulb Watts                 LED Bulb Watts

40                                                 10                                                  4

60                                                 15                                                  7

75                                                 20                                                 11

100                                               26                                                 18

LED bulbs do not emit as much heat as halogen, incandescent, or fluorescent bulbs.  LED’s are known for producing a “cool” light.  This means that not only are they more comfortable to be around, but during the summer your air conditioner has to work less to cool down the additional heat produced by the lighting in your home.  Thus, your electricity bills are lowered in more ways than one.

LED’s do not contain mercury, which is toxic, so they will not poison the landfills to the extent that fluorescent bulbs will.  If fluorescent bulbs are broken, the mercury can be absorbed by the skin so we have to be more careful with them and recycle them properly.  Additionally, LED bulbs last longer, so it will be many years before one has to be disposed in a landfill.

LED bulbs turn on immediately when the switch is lit and their lights do not flicker.  Incandescent lights and fluorescent lights with magnetic ballasts usually take some time to warm up before they turn on and their lights flicker.

Earlier versions of LED bulbs were not capable of dimming but new technology has fixed that.  Today, many LED bulbs are designed to work with dimmable switches provided for lamps and lighting fixtures for homes.

Disadvantages of LED lights

The downside of LED’s is that they offer a more direct light than a flood type of light.  This means that they are good for spot lighting, but not as good for illuminating an entire room as florescent lights.  LED bulbs for everyday home use are a bit pricier than and not as available as fluorescent lamps.  An LED bulb for a desk lamp can cost $20-$30.

In conclusion, LED bulbs have many benefits going on for them.   Household LED light bulbs will outlast regular bulbs and can last more than 10 years.  As of now the issue is whether someone wants to pay the initial higher price for a more energy efficient and environmentally friendly bulb.  In the long run, it pays to buy an LED bulb for your home.
