What is LED lighting?

 

LED lights are the latest technology in energy efficient lighting. LED stands for ‘Light Emitting Diode’, a semiconductor device that converts electricity into light.

 

LED lights are super energy efficient, using approximately 85% less energy than halogen or incandescent lighting – meaning significant savings on your power bills. LED lights also have a much longer lifespan than other types of lighting - see the table below.

 

Lighting technology Estimated lifespan*
LED 25,000-50,000 hours
CFL 8,000-15,000 hours
Halogen 1,000-5,000 hours
Incandescent 1,000 hours

*Depending on the globe

 

What are the other types of lighting?

 

Incandescent

Incandescent globes look like the traditional ‘Edison’ shaped light bulb, with a filament strung across two metal bars in the centre of the globe.

 

Due to government regulations, as of November 2009 you are no longer able to purchase standard incandescent globes. These globes were extremely inefficient because they only converted 5-10% of the energy they produced into light, while the remainder was converted to heat. The result was an extreme waste of electricity.

 

Halolux

Halogen globes will look similar to incandescent globes, but it uses an envelope filled with Halogen low pressure Halogen gas to help burn the filament to produce the visible light. In addition, regular 12 volt downlights that have not been changed to energy saving fittings are likely to be halogen.

 

These globes have typically replaced incandescent globes, for example in pendant lights, chandeliers and spotlights. Newer energy saving halogens – called eco-halogens – are now available and are about 30% more efficient than incandescent globes. All of the halogen globes you’ll find on our website are eco-halogens.

 

CFL (Compact Fluorescent Lamp) - Envirolux

CFLs are fluorescent tubes twisted into shape to fit a standard light fitting. CFLs are about 80% more efficient than incandescent globes but have some restrictions, such as dimming size and the appearance.
