Energy Efficient Long Life LED Lamps vs Halogen Lamps

Direct Replacements & Innovative Alternatives

LED direct replacement lamps are now available for 2pin and screw base Halogen Lamps. With a life expectancy of 40,000 hours, they would last 4.5 years, if left on 24hours, 365 days a year. The electricity costs would be about 10% of the equivalent Halogen lamps. This makes them ideal spotlights in libraries, shops and galleries.

In the case of Downlights and Tracklights, each 2-Pin 12 Volts Halogen Lamp uses 35W whereas the LED equivalent uses just 3.8W (4.5 LED replaces 45W Halogen).

In bathrooms which are only used for a short period and require bright lighting there are 9W and 15W Screw Base LED Lamps available to directly replace unsatisfactory CFL or 60Watt,75Watt and 100Watt Incandescents or their Halogen equivalents. LEDs provide instant light.

Maxxima has a range of Cool White LED Edison Screw Base Lamps (Globes/Bulbs) rated at 40,000 hours. A 9W LED with equivalent Light of 60W Incandescent, a 15W LED Pearl with equivalent Light of a 75W Incandescent and a 15W clear cover LED Equivalent Light of a 100W Incandescent

While LED Lamps are more efficient they do generate heat at their base. Lamps are being designed to dissipate the heat but the manufacturers specifications should be read and followed.

Fire Threat of Halogen Downlights

"Over the past five years there have been a significant number of fires in NSW related to halogen down-lights. Halogen down-lights create a lot of heat and if they are not correctly insulated, installed and maintained they can cause a fire. Halogen lights generate very high temperatures which can get anywhere up to 370C....Never install halogen down-lights near structural timber members such as roof, ceiling or floor beams.... Ensure the lights and transformers are not covered by ceiling insulation such as pulped paper, rock wool, fibreglass batts or polyester batts. The heat from the lights can cause the insulation to smoulder or ignite.When having renovations or work done to the home, ensure the existing ceiling insulation does not come in contact with the halogen down-lights..." - NSW Fire Brigade Fact Sheet (23 February 2010)

Comparative Lamp Technology Lifetime Source: Fact Sheet Lighting Council of Australia (October 2008) manufacturers have begun using the L₇₀ language, stating that their white LEDs "are projected" to have lumen maintenance of greater than 70% on average after 50,000 hours when used in accordance with published guidelines.
Light Source	Range of Typical Rated Life (hours)* (varies by specific lamp type)	Estimated Useful Life L₇₀
Incandescent	750-2,000
Halogen incandescent	3,000-4,000
Compact fluorescent(CFL)	8,000-10,000
Metal halide	7,500-20,000
Linear fluorescent	20,000-30,000
High-Power White LED		35,000-50,000
