Evolution of light bulbs from candle to LED

Changing your lighting can be the most cost-effective and easiest way to reduce your power bills. Lighting in homes accounts for 8 to 15 per cent of the average household electricity budget so it’s one of the first and easiest places to make efficiency savings.

Thomas Edison patented the first commercially viable incandescent light bulb more than 130 years ago but the last ten years has seen the rise of energy efficient LED lighting to replace old technology.

However, recent research suggests we may see a “back to the future” return of the humble Edison globe in our lifetime.

Incandescent light globe 

The humble Edison light bulb, an incandescent light globe with a wire filament heated to a high temperature to produce a glow, has been replaced with a more energy efficient LED lighting.

In the past ten years LED lighting has become more common and can replace most standard lights used in and around homes.

LED lights are a smart choice, they are reliable and last longer than an incandescent light bulb.

Pros:

• Light up immediately, like an incandescent bulb • Don’t heat up much at all – they stay cool to the touch even after use • No sensitivity to cold temperatures 
• Do not contain mercury 
• Some models can be used with a dimmer switch • Available in soft, warm, and bright white hues 

It’s important for you to replace both your light and the transformer in your roof for optimal performance. Just replacing your globes will not achieve the same results.

When performing together, an LED globe and transformer may last 10 times longer than traditional halogen lighting and it produces the same amount of light with less wattage.

Back to the future 

By revisiting the incandescent globe, with its warm glow and instant light, researchers at MIT may have found a solution to marry this old faithful with 21st century energy efficiency.

MIT says whereas the luminous efficiency of conventional incandescent lights is between 2 and 3 per cent, fluorescents (including CFLs) is between 7 and 15 percent, and that of most commercial LEDs between 5 and 20 percent.

The new incandescent they have developed could reach efficiencies as
high as 40 percent, the team says.

According to MIT, the first proof-of-concept units made by the team do not yet reach that level, achieving about 6.6 percent efficiency. But even that preliminary result matches the efficiency of some of today’s CFLs and LEDs, they point out. It is already a threefold improvement over the efficiency of today’s incandescents.
