LED is describe by Rudy Provoost, CEO of Philips Lighting as the most significant development in lighting since the invention of electric light almost a century ago.

Below are the pros and cons of LED lighting. As you can see there are more advantages than disadvantages. It is almost certain that LED lighting will become the standard lighting of the future.

Here is a list of the disadvantages of LED

LED bulbs last up to 10 times longer (about 60,000 hours) than incandescent or fluorescent bulbs.

LED bulbs generate little heat, which mean it stay cooler than other light bulbs.

It does not contain any mercury or toxic material, which makes it environmental friendly.

LED lighting use less energy. For example, a LED light bulb with 5-7 watts is equivalent to a 60-watt incandescent bulb or a 15 watts compact fluorescent lamp.

LED instantly light up and does not require warming up like compact fluorescent lamp.

It save you money on your utility cost.

LED are more durable than incandescent or fluorescent lighting.

Because of its long life span, LED are use on trucks tail lights, and other lighting for safety proposes.

It is economical to purchase LED bulbs even if other light bulbs are free. If a LED bulb cost $50 dollars. It is still inexpensive to purchase the $50 dollars LED bulb because LED will save you more money on your utility cost over the long haul.

The lighting industry considered LED lighting as the future of lighting.

Rudy Provoost, CEO of Philips Lighting believes solid-state or LED (light emitting diodes) lighting is the most significant development in lighting since the invention of electric light almost a century ago. Offering unprecedented freedom in terms of colors, dynamics, miniaturization, architectural integration and energy efficiency, solid-state lighting is opening up exciting new possibilities. Philips introduces industry-changing lighting transformations, solutions

“LED technology has opened up so many possibilities in terms of its ability to reduce carbon and give us instant control of light.” said Mike Simpson, Technical and Design Director at Phillips. The future of lighting: LEDs lead the way

LED lightings are not cheap. As LED technology become more common, along with more competitions, the price should slowly drop.

The light emanates from the top half of an LED bulb are directional. It does not produce ambient light or scatter the light in all directions. This type of directional lighting is suitable for spotlight but not for general ambient lighting, but there are general-purpose LED bulbs available that does reasonable job.

  1. Good read. Thanks for the information.

  2. Frank says:

    LED bulbs are the way of the future. My uncle actually makes his own LED lighting fixtures to compensate for the pricing as well as the ambient lighting you mentioned. You can easily use LED lighting to flood rooms if you make your own.

  3. Jess D. says:

    You might want to do more research on LED's. They will save residential consumers money, because power companies only charge residential for wattage. Commercial properties are charged VA (volt amps) and the VA consumption for LED's are huge, and when you trace it back to the source (power plant) it takes more energy to produce the VA required to run LED's then it does to run CFL's. They are actually worse for the environment.

    • Tony N. E. Eng. says:

      Correct me if I'm wrong, but an LED bulb must convert the incoming AC current to DC for it to function, since they are diodes after all.
      So in a simple resistive DC circuit (the bulb) VA is the same as Watts.

      VA is only different to Watts where power factor is involved, in capacitive and inductive circuits.
