The free CFL light bulbs, available from Free Energy Saving Light Bulbs and Installation, produce about 75% less heat, so they are safer to operate and can cut energy costs associated with home cooling.
The Incandescent light bulbs were invented by Thomas Edison in 1879, and the basic design has not changed much since. These bulbs are inefficient, converting only 10% of the electricity consumed into visible light. The remaining 90% of the electricity is actually released as heat.
Over its lifetime, Free Energy Saving Light Bulbs and Installation’s free light bulb eliminates the need for eight incandescent bulbs and saves more than AU$30.
When people choose free energy efficient light bulb, they are making a difference for the environment by reducing air pollution and greenhouse gas emissions.
Different types of light bulbs, such as compact fluorescent lamps (CFLs), deliver the same light output as incandescent light bulbs but use 75% less energy.
When comparing different types of lighting, designers use the term “efficacy.” The efficacy (or efficiency) of a light source is the ratio of lumens produced to watts consumed. Light output is measured in units called “lumens.”
Free Energy Saving Light Bulbs and Installation’s free energy-efficient light globes in the ceiling fans with lights are about 50% more efficient than conventional fan / light units, saving more than $15 per year in energy costs.
The CFL bulbs use approximately 70% less energy than incandescent bulbs and produce the same light. It is estimated that the compact fluorescent bulb will last as long as 10 incandescent bulbs saving energy and money each year.
- 5W CFL = 25W reg. bulb
- 8W CFL = 40W reg. bulb
- 10W CFL = 50W reg. bulb
- 11W CFL = 60W reg. bulb
- 15W CFL = 75W reg. bulb
- 20W CFL = 100W reg. bulb
- 23W CFL = 120W reg. bulb
History
The parent to the modern compact fluorescent lamp (CFL) was invented in the late 1890s by Peter Cooper Hewitt. The Cooper Hewitt lamps were used for photographic studios and industries.
Edmund Germer, Friedrich Meyer, and Hans Spanner then patented a high pressure vapour lamp in 1927. George Inman later teamed with General Electric to create a practical fluorescent lamp, sold in 1938 and patented in 1941.
The modern CFL was invented by Ed Hammer, an engineer with General Electric, in response to the 1973 oil crisis. While it met its design goals, it would have cost GE about US$25 million to build new factories to produce them and the invention was shelved.

Switching from traditional light bulbs (called incandescent) to CFLs is an effective, simple change everyone in Australia can make right now.
Making this change will help to use less electricity at home and prevent greenhouse gas emissions that lead to global climate change.
Lighting accounts for close to 20% of the average home’s electric bill. Free Energy Saving Light Bulbs and Installation’s qualified CFLs use up to 75% less energy (electricity) than incandescent light bulbs, last up to 10 times longer, cost little up front, and provide a quick return on investment.
If every home in Australia replaced just one incandescent light bulb with Free Energy Saving Light Bulbs and Installation’s qualified CFL, in one year it would save enough energy to light more than 3 million homes. That would prevent the release of greenhouse gas emissions equal to that of about 800,000 cars.
