Incandescent
lamps
Incandescent lamps work when
electricity passes through a wire
filament to create energy. In use
for more than 125 years,
incandescent lamps are very
inefficient because they convert
only 5 to 10% of the energy they
produce into light, and the
remainder is converted to heat.
Experts estimate that there are up
to 500 million incandescent light
globes in Australia. As of
November 2009, due to the new
government regulations you’ll no
longer be able to purchase standard
incandescent globes.
Halogen
lamps
Low voltage halogen downlights are
the most commonly used light globes
in Australia. They are a type of
incandescent lamp and although they
require lower voltages they are not
low energy lamps. In fact each low
voltage halogen lamp generates a
kilogram of greenhouse gas every 15
hours which is about the same as a
standard 60 watt incandescent globe.
The refit of low voltage halogen
downlights requires a special light
fitting therefore you need the
services of an electrician to
replace them with CFLs. For new
homes and renovations, there are a
range of CFL downlights available.
Compact Fluorescent Lamps (CFLs)
CFLs work by passing an electrical
current through a gas which
activates phosphor powder to give
light. Put simply, they are
fluorescent tubes bent into shape to
fit a standard light fitting.
CFLs use around 20% of the power
required by an incandescent bulb and
will last four to ten times longer.
CFLs are available in a range of
colour outputs and designs to suit
many existing light fittings around
the home and office. For more
information see the Fact Sheet –
CFLs.
Light Emitting Diodes (LEDs)
LEDs are the next generation of
lighting, illuminated solely by the
movement of electrons in a
semiconductor material. They don’t
generate heat, contain no chemicals
such as lead or mercury, and emit no
UV rays or infrared radiation.
LEDs are now available as a real
option for replacing the commonly
used halogen downlight. The recently
released LEDlux downlights work very
similar to common halogen downlights,
but use 85% less energy, last 25
times longer and operate at a much
cooler temperature, making them a
safer option. Shop our range of LED
downlights online
LEDs are also widely available in
desk lamps and outdoor garden
lights, with brighter products
generally being more expensive.
Solar Lighting
Commonly used in gardens to light
pathways, solar lighting is the
ultimate ‘green’ lighting
alternative. Solar lighting is
entirely self-sufficient and
requires only the energy from
sunlight to convert into electrical
energy.
