Change to LED's and cut your lighting power bill by 66% instantly and in many cases up to 90%
See Your Home In A Whole New Light
LED's are a revolution in lighting. They use very little energy, they hardly ever need changing and they contain no harmful mercury. LED's incredibly long working life and low energy requirements mean that in addition to effectively replacing existing lighting we can begin to use lighting in new ways, creatively incorporating light into architectural and interior design.
When making the change to LED's we need to shift our thinking from the idea that light bulbs are a low quality 'throwaway' item. High Power LED's are very high quality, robust, attractive appliances that give light. Think of them more as you would a light fitting because in many cases they will last just as long.
Did you know that in 2007 the Australian government enacted a law that will ban the sale of most incandescent lightbulbs by 2009? Until now compact fluorescents have been our only alternative, they do save energy but they contain dangerous levels of highly toxic mercury which make them anything but 'green'. LED's are the energy saving, environmentally friendly choice in lighting.
This comparison table is a careful assessment of various types of lighting that will give the equivalent amount of light to a 60W incandescent bulb. Many LED comparisons will misleadingly show a cheaper purchase price and a lower wattage but they are simply not bright enough to be considered a true alternative to a standard 60W bulb. The LED Model we have based this comparison on is the G605C you can find it with our high power bulbs. Of course there are many applications where this level of light is not required. LED's that have a lower light output such as a decorative candle bulb equivalent to a 20 Watt incandescent bulb use only 1.8 Watts of power and can be purchased for around $10.

Description |
Electrical current
passes
through a
thin tungsten filament
heating it
until it
produces light. |
Similar to
incandescent
but halogen
gas enables it
to operate
at higher
temperatures
making it
slightly more
energy efficient. |
A tube is
coated with
phosphor salts
and is filled
with a gas
containing low pressure
mercury vapor.
A heated
tungsten cathode then fires off
electrons which react with the
phosphors to
create light. |
Light emitting diodes
produce light
through a solid state
process called
electroluminescence. |
|
Power Used |
A 60 Watt bulb
uses 60 Watts. |
Approx
50 Watts. |
15 Watts
About
one-quarter the
power of an incandescent
bulb. |
6 Watts
One-tenth the power of an incandescent bulb. |
|
Heat Generated |
The glass coating of a general service
light bulb
can reach temperatures
of over 200 degrees Celsius. Over 95% of energy used is wasted as heat. |
The bulb
surface must
be very hot, generally over
250 degrees Celsius. |
Fluorescent lights emit around 30% of
their energy output as heat. |
LED’s generate a small amount of heat at their electrical connection (approx 50-60 degrees Celsius) but the light itself emits no heat whatsoever. |
