How much can you save by replacing 50W halogen downlights?
The following table shows the main energy-saving alternatives to 50W halogen downlights.[1]
| Alternative lighting | Estimated lifespan of new lighting | Estimated running cost reduction [2] |
| 35W infrared coating (IRC) halogen lamp (without an electronic transformer) [3] | up to 2,000 hours [4] | 31% |
| 35W infrared coating (IRC) halogen lamp (with an electronic transformer) | up to 6,000 hours [5] | 42% |
| 15W compact fluorescent lamp | up to 16,000 hours | 70–80% [6] |
| New 13W compact fluorescent luminaire | up to 16,000 hours | 70–80% |
| 16W LED luminaire (replaces lamp and control gear)% [7] | up to 50,000 hours | 60–80% |
| 7W LED retrofit replacement lamp (no new equipment needed) [8] | up to 50,000 hours | 60–83% |
When it comes to installing these alternatives, talk to an EcoSmart Electrician, your local electrician or a specialist lighting store about what you can do yourself and what needs to be professionally installed.
The benefits of LED downlights
When it comes to replacing a 50W halogen downlight, a LED downlight is your best money-saving solution. In addition to lasting up to 50,000 hours, they give out a high-quality light and use up to 83% less energy. They can also be dimmable.
Kerry’s Automotive Group, NT
Kerry’s Automotive Group have saved more than $25,000 a year by making extensive changes to their lighting. They have switched from high-intensity halogen lights to more energy-efficient LEDs.
They’re also using a timed electrical system that turns off the lights when they’re not in use. The Systems Manager Corey Heuvel, says the LEDs are not only saving money, but providing ‘cleaner light’ too.[9]
Fire and halogen downlights
If they are not properly installed, maintained and insulated, halogen lights can be dangerous.
Fire and Rescue NSW have stated that there have been a significant number of fires relating to halogen downlights over the last five years.
That’s why it makes sense to replace halogen lights with a low-heat LED alternative.

- 1. A more detailed version of this table is available on page 25 of the NSW OEH ‘Energy Saver Energy Efficient Lighting Technology Report’
- 2. This is dependent on the quality of lighting that you buy.
- 3. The 35W infrared coating (IRC) halogen lamp (without an electronic transformer) can be placed into the existing halogen fitting. Similarly, the 10W LED lamp can also fit into the existing halogen fitting. Check with your lighting technician to see if it’s more cost-effective to totally replace the existing light fittings. Over time, this may save you more money.
- 4. This is dependent on the brand. Some cheap halogen downlights can last for only 1,000 hours.
- 5. This is dependent on the brand. Many cheaper varieties will not last this long.
- 6. According to the NSW OEH, CFL ‘light output may be very low and not at all like the existing output’.
- 7. This is the recommended option in the NSW OEH ‘Energy Efficient Lighting Technology Report‘.
- 8. Check the LED retrofit lamp is compatible with the existing transformer in the ceiling. If you are dimming the new LED, check the compatibility with the dimmer as well.
