40 Watt: Halogen Energy Saver Downlight Bulb: GU10: 240v: Osram

This pack contains one energy saving 240 volt halogen downlight bulb. These bulbs use a special infra-red coating (IRC) that helps produce the same amount of light with approximately 25% less energy as a standard halogen downlight.

This means you can repace your current 50 watt halogen downlight with this 40 watt bulb and produce the same light output.

This bulb features:
- a large two nail head style connector (GU10).
- a soft, comfortable, warm light.
- a 2,000 hour life expectancy.

Buying tips:
There are two types of downlight bulbs that look similar but are very different.

This type of downlight bulb is the GU10 mains downlight bulb. It has a larger connector (looks like two large nail heads) and does not require a transformer as they operate on 240 volt mains power.

The other type of downlight bulb is a 12 volt downlight and has two small pin connectors. These lights use a transformer in your roof to convert the mains 240 volt electricity to 12 volt. These transformers also use up valuable energy.

Halogen IRC bulbs are a good entry level power saving measure for your 240 volt downlights, however for bigger savings, consider changing to compact fluorescent downlights (CFL).

CFL downlights last up 15,000 hours (reducing waste), and you could save over 70% on your energy costs compared to your standard downlights. For more info see the related products at the bottom of the page.
