LED’s are becoming more and more common.

They look attractive with crystal luminaires

Can change colour, more for effect

Can have dimmers

Can be very bright

Australian Standards (1st May 2011)

Maximum of 5 watts per metre squared inside a house

Maximum of 4 watts per metre squared outside

Maximum of 3 watts per metre squared for a garage

New houses must comply

Older houses exempt

Not all down lights are interchangeable between halogen and LED lamps

Halogens can be energy savers, 20 watt gives 100 watts of light

History of lighting

Candles > Gas Lamps > Electric bulbs/lamps (incandescent) > fluorescent > halogen

Types of lamps (artificial lighting)

Incandescent- Phased out as they overheat, have short lived use and are not cost effective in terms of electricity

Fluorescent- “diffused light”; long lived, energy efficient

LED- light emitting diodes; low running costs, great for decorative lights

Halogen- work in the same way as incandescent, different gas, reflectors within bulb, strong light, overheat easily, not very sustainable

Sodium- street lights, yellow glow

Metal Halide- works in same way as halogen and incandecent, halide gas used, take time to warm up and cool down, commercial use only

Neon-Good for signage

Watts – more watts per lamp – more electricity used

Incandescent– approx. 6o watts per lamp

Fluorescent – 11 watts per lamp

Halogen – 120 watts per lamp

Phillips– Lighting company
