Houses typically use a mixture of standard light fittings and downlighters or spotlight fittings. Energy efficient bulbs are available for both types of fittings.
Changing which bulbs you use and how you use them will instantly save your home energy and money.
There are two main types of energy efficient light bulbs available in the US. Compact Fluorescent Lamps (CFLs) and Light Emitting Diodes (LEDs)
CFLs are what you typically think of as an energy efficient light bulb. CFLs are a cost-effective option for most general lighting requirements. Replacing a traditional light bulb with a compact fluorescent light bulb (CFL) of the same brightness will save you around $5 per year, or $75 over the lifetime of the bulb.
LEDs are available to fit both types of fittings and are particularly good for replacing spotlights and dimmable lights. Though more expensive to buy initially, they are more efficient than CFLs and will save you more money in the long term. By replacing all halogen downlights in your home with LED alternatives, you could save around $65 a year on your electricity bills.
