Choosing the right energy efficient bulb
There are different types of energy efficient light bulbs to choose from. Watch the video and read the info below to find out which bulbs to use where.
- Very efficient and very long life: use up to 85% less electricity than traditional incandescent light bulbs and can last more than 15 times longer.
- Good for most general lighting around the house.
- Available as replacements for standard GLS light bulbs, spotlights and recessed downlights.
- Instant full brightness
- A good choice for people who don’t like the mercury in CFL bulbs.
- Dimmable versions available.
- 'Warm white' and 'cool white' light colours to choose from. 'Warm white' provides a more comfortable light suitable for homes.
- For recessed downlights, replacing the whole fitting with a dedicated LED downlight is recommended.
Compact fluorescent lamps (CFLs)
Cost less to buy than LEDs.
Efficient and long life: use up to 80% less electricity than traditional incandescent light bulbs and last more than 6 times longer.
Good for most general lighting around the house where the lights are on for more than a few minutes.
Available as replacements for standard GLS light bulbs.
Can take a minute to reach full brightness.
Frequent switching can shorten their life.
- Contain a small amount of mercury. Although studies indicate this does not pose a health issue, it would be best to avoid using the bulbs in areas where they could easily break because special clean up procedures are required.
- Best for lights where an almost identical look of standard incandescent bulbs is more important to you than efficiency.
- Use up to 30% less electricity than traditional incandescent light bulbs, but use 3 to 5 times more than LEDs or CFLs of similar brightness.
- Can last twice as long as standard incandescents.
