What does colour temperature (4000K) represent?

Energy saving lamps are measured in Kelvin, which is a precise measurement for heat.

A bulb with a lower Kelvin, such as 2700K, will give off a warm light whereas a 6000K bulb will emit a very white light, much like daylight. The higher the Kelvin rating, the higher emitted light.

Colour temperature guide (Kelvin)
This table can be used as a guide to the kind of light you should expect from your energy saving light bulbs.

How do I know which base to order?

There are 2 types of bases available. One is the Bayonet Cap fitting and the other is the Edison Screw fitting. Bayonet caps are usually used in UK appliances whereas Edison Screw fittings are used in European and American appliances, such as imported chandeliers, table lamps and so on.

Which size?
Edison Screw and Bayonet Caps come in both small and large types:

E14 (14mm diameter) and E27 (27mm diameter) are Edison Screw

B15 (15mm diameter) and B22 (22mm diameter) are Bayonet Cap

Typical fitments...
Generally speaking, table lamps and ceiling Rose lights will require a B22 large Bayonet fitting. A chandelier, (imported from Europe) with its more delicate structure, would usually need the smaller Edison E14 Screw type.

Screw fittings are also known as ES fittings, which stand for Edison Screw. Edison is the man who invented the screw fitting. Popular in the UK, Bayonet fittings are also known as BC caps.

What is the difference between Aluminium and Dichroic reflectors?

There are two types of reflectors, Aluminium and Dichroic. Which one you should choose all depends on what you plan to use them for. Aluminium reflectors reflect the heat and light forward. Dichroic reflectors reflect the light forward and the heat sideways and backwards.

Recommended Use
Aluminium reflectors are much safer in ceiling lighting.
Dichroic reflectors are ideal for shop lighting, where you would like to illuminate a product without heating it up. E.g. Foods and fabrics.

How much will I save using Energy Saving lamps?

You can expect to save in the region of 80% of your electricity costs!
Lumineux lamps are manufactured using the most advanced technology. These energy saving lamps use only 20% of the electricity when compared to a standard incandescent light bulb.

How do the wattages compare with standard bulbs?

Energy Saving lamps will use approximately 80% less energy than standard light bulbs, meaning a 20W Energy Saver can replace a 100W standard bulb. Colour temperature (i.e. 4000k) contributes to the light given off by a bulb.

Replacing your standard light bulbs

The comparison table below can be used as an approximate guide to selecting the closest Energy Saving equivalent.

Do energy saving lamps get hot?

You can quite comfortably hold a low wattage lamp (up to 13w) in your hand whilst it’s on. Whilst the 15w and 20w lamps do get slightly hotter they are no where near as hot as a standard light bulb.

Energy Savers are particularly safe for table lamps, children’s bedrooms, nursing homes etc.

Are Energy Savers much bigger than normal lamps?

They certainly used to be larger when the first energy savers were introduced, as the technology wasn't available to reduce their size. New technology has enabled these lamps to be drastically reduced in size!

The smallest types are now very close to that of a standard light bulb.

Can I dim energy saving lamps?

Unfortunately these bulbs cannot be dimmed as they have an electronic starter.

Why are Energy Saving lamps slow to start up?

The first energy saving lamps were very slow to start up, nowadays the lamps are equipped with more advanced starter packs - they now reach full brightness within seconds!
