Light colour is measured in Kelvin. The higher the Kelvin level (K) the 'colder' the light will appear. Generally, for living areas you will require a lower light colour, around 3000K, which is often called 'Warm White' (this light will look yellowish). For areas such as kitchens you would likely use 4500 - 6000K which is referred to as Cool White - this light can seem blueish.

See the simple guide below to see this explained. Please note that this guide is just representative.

No. The wattage only determines the amount of power the bulb uses. The value that determines the brightness of a bulb is the lumen level. The higher the lumens the brighter the bulb will appear.

A. Incandescent lamps (see below) have a variety of different fittings.

Bayonet Cap has two abbreviations - BC (B22) and SBC (B15). These relate to the size, BC is larger and SBC (small bayonet cap) is a smaller fitting.

Edison Screw also has two abbreviations - ES (E27) and SES (E14). Again, these relate to the size of the fitting.

To help you identify the fitting, try our hand fitting identifier!

The IP (Ingress Protection) rating of a product, describes the resistance the product offers to the penetration of various solids and liquids. This is always a 2 digit number. The first digit identifies the protection against solids and the second digit against liquids.

First Digit (protection against solids) Second Digit (protection against liquids)
0 No protection 0 No protection
1 Protected against solid objects greater than 50mm (eg contact with a hand) 1 Protected against vertical water drops (eg condensation)
2 Protected against solid objects greater than 12mm (eg contact with a finger) 2 Protected against direct sprays of water up to 15° from vertical (eg condensation)
3 Protected against solid objects greater than 2.5mm (eg tools & wires) 3 Protected against direct sprays of water up to 60° from vertical (eg condensation)
4 Protected against solid objects greater than 1mm (eg fine tools & wires) 4 Protected against water sprays from all directions
5 Protected against dust 5 Protected against low pressure jets of water from all directions
6 Total protection from dust 6 Protected against jets of water similar to the force of heavy seas
  7 Protection against immersion between 15 - 100cm
  8 Protection against submersion

So for example IP65 indicates a product has total protection against dust and protection against low pressure jets of water.

There are 3 main types of lightbulbs: Fluorescent, Incandescent & Halogen.

Fluorescent. These bulbs contain gasses in a tube and have no filament. These bulbs are often known as the long tubes which are seen on ceilings. Recent technology has allowed these bulbs to be made much smaller and increase the efficiency. They have also been made into much more desirable shapes, such as sticks and spirals. These bulbs have a low power consumption and are ideal for places that need to be kept on for long periods of time.

Incandescent. The traditional filament bulb. These are the bulbs that many people will recognise and be used to having in their house. The advantage to this type of bulb is the colour they emit, and they give the room a 'warm' feeling. The disadvantage to this type of bulb is that they are energy inefficient and have a short life, which is around 1000 working hours.

Halogen. Filament bulbs containing halogen gasses. This type of bulb produce a light which closely resembles sunlight. They are 50% more efficient than incandescent, using half the energy to produce the same light levels and generally have a life of around 2000 hours. The down side to halogen bulbs is that they produce a lot of heat and can only be used in fittings designed to cope with this high heat level. More recently the GU10 reflector and G9 fittings have become very popular bulbs for domestic and commercial situations.

There is a rough calculation you can do to determine the amount of light you should have in a room.

Measure the room in square metres and multiply this by 25 (if you require incandescent bulbs) 15 (if you require halogen bulbs) or 19 (if you require fluorescent bulbs). This final figure will give you the total wattage required to light this room.

Example. A room is 5m x 5m which has an area of 25m2. We want to light this room using traditional incandescent bulbs, so we multiply 25 by 25, giving a total wattage requirement of 625W. We can make this up by using the following:

Fitting & lamp Wattage
2 x table lamps with 75W bulbs 150W
2 x 3 bulb chandeliers with 40W bulbs 240W
2 x double wall lights with 40W bulbs 160W
2 x single wall lights with 40W bulbs 80W
  Total: 630W

Please Note: The above calculation is as a guideline only. Some people prefer more lighting, others less. One option is to over estimate by 10-15% and install a dimmer allowing for more control over your lighting.

PIR stands for Passive Infrared and is used on many lighting products as a motion sensor. For lighting products it is usually used to switch a light on when the sensor detects motion - such as on a security light. To see all of our products which use PIR sensors, click here

The lumen level (lm) relates to the 'total amount of visible light emitted by a source'. The higher the lumen level of a bulb, the brighter the light will be.

There are a number of common types of fittings. If you are unsure what fitting type you need, use our handy fitting identifier guide!

We try to make your buying process as easy as possible, so we have added specifications to many products.

For switches and sockets, Ingot refers to the fact the switch is the same colour as the plate, rather than just black or white.

Modern CFLs (Compact Fluorescent) only take a few seconds to warm up to full brightness. LEDs reach full brightness instantly.
Yes, if you buy the right energy saving bulb it will be just as bright as the one you’re replacing.
LEDs run significantly cooler than Halogen and Fluorescent bulbs, but they still do get hot. Good quality LED bulbs have efficient metal heat sinks on the back, which dissipates the heat which keeps the bulb cool. This in turn helps towards the long life span of an LED bulb.
A fire rated downlight seals the hole in the ceiling allowing for up to 90 minutes of protection against the spread of fire. The fire rated fittings are often more expensive than non-fire rated, due to the fire protection materials which go into producing them.
Yes, LED bulbs are designed to be a like for like replacement for your halogen bulbs. In some rare cases your existing fitting may require a taller lamp.

The price of buying an LED bulb compared to buying a halogen one is higher, but over the life of the bulb you will save a lot of money due to two main reasons: 1 - The LED bulb is much more energy efficient, 2 - the LED bulb will last a lot longer.

Take this calculation as an example. You kitchen contains 6 x 50W halogen lamps which you have switched on for 6 hours a day. At 13p per kW Hour, this room would cost you £85.41 to light per year. If you replaced these 6 bulbs with 6 x 4W LED bulbs this room would cost you £6.83 per year to light. Saving you £78.58 per year.

The average Halogen bulb has a life of approximately 2000 hours, which equates to 0.9 years if using for 6 hours a day.
The average LED bulb has a life of approximately 30,000 hours, which equates to 13.7 years if using for 6 hours a day.
