When it comes to home energy efficiency, lighting may not seem like a major concern, but it accounts for around 7% of the average household energy bill and if you’re still using old halogen or incandescent bulbs, you’re likely spending more than you need to. Switching to LED lights is a simple upgrade that can lead to noticeable savings over time.
What’s the Problem With Older Globes?
If your home still has halogen or incandescent globes, you’re using outdated technology that:
- Converts up to 90% of electricity into heat—not light
- Burns out faster and needs replacing more often
- Can pose a fire risk in some fittings due to heat build-up
- Costs more to run over time
Energy Cost Comparison: Incandescent vs LED Globe
*Based on average usage of 4 hours per day and a standard electricity rate of ~30c/kWh (typical for many Australian households).
This graph compares the cumulative energy costs over five years for a single incandescent globe versus an LED globe. The growing gap shows how quickly the savings from an LED add up, with up to $100 saved per globe over just five years. (https://www.choice.com.au/)
This chart illustrates the total five-year savings when replacing 10, 20, or 30 incandescent bulbs with LEDs. It demonstrates how even a small switch across the home can result in hundreds—or even thousands—of dollars in energy savings over time. (https://www.choice.com.au/)
The Benefits of Switching to LED Lighting
- Up to 80–85% lower energy use compared to incandescent globes
- Save around $20 per year per globe in energy costs
- Longer lifespan means fewer replacements and less maintenance hassle
- Lower replacement costs, especially in hard-to-reach fixtures like ceiling lights
- Cool to the touch — safer for homes with children or pets
- Reduced eye strain and minimal flicker for better comfort
- Dimmable and colour-adjustable options for mood and comfort
- Better light quality for everyday tasks and ambiance
- Available in a wide range of fittings — downlights, tubes, globes, panels
- Work seamlessly with smart lighting systems and dimmers
- No heat build-up or toxic materials (unlike some CFLs)
- Improves home safety and comfort overall
- Increases appeal for buyers or tenants — a smart selling point for energy-conscious households
