About Downlight Converter
A downlight converter is used when replacing an old-style downlight to a newer style one. Old style downlights are quite large, and leave a large hole in the ceiling which is not filled by a smaller, newer downlight. A downlight converter will cover the hole left by the old light, and convert to either a mains halogen, low voltage halogen, low energy or LED light fixture.
When choosing a downlight converter, it is important to check which type of light you require. Bear in mind how many hours' life a typical bulb has, but also how expensive a replacement bulb is to buy, and how much energy the lights use up. If a bulb lasts for 5000+ hours, but uses twice the power of your previous fitting, you may find your electricity bills rising, regardless of when the bulb need to be replaced.
You should also check whether you need any adaptors to fit the downlight converter, and if so, whether these come with the converter. Equivalent light output is important too. If your old light used a 100 watt bulb, you want something that will provide similar light, or you may find yourself replacing the light fitting again in a few months.
One very important thing, is to measure the diameter of the hole you want to cover, and ensure the downlight converter you choose is large enough. It's also important to note the type of light fitting you are replacing, for example R80 or R50, and ensure that the converter is suitable for this.
