What is a watt?

A watt is a measure of power consumption. The wattage of a bulb actually tells you how much electricity it uses, not how much lights it produces. Traditionally lamps have always used watts as an indication of the lights that can be expected from the bulb. However, with new technology and more efficient lamps, watts are becoming increasingly irrelevant and eventually all lamps will be measured in Lumens.

What is a Lumen?

Lumens are a measure of light. Typically one lumen is equivalent to the light emanating from a single wax candle. A conventional 40 watt light bulb would have a lumen output of around 450lm. A CFL with the same lumen output would only use approximately 9 watts and an LED considerably less depending on the type. As a general guide the efficiency of an incandescent lamp is 10-12lum/w, a CFL is around 50 - 60lum/w and an LED can vary from 40 - 110 lum/w. Remember: the higher the lumens the brighter the lamp.

What does voltage mean?

Voltage is the pressure within the circuit that's generated by the electricity company from the national grid. Different countries use different voltages according to their infrastructure system, its generally referred to as the electrical potential.

In the UK the current used is typically 240 volts, in America 120 volts and in most if Europe and the Far East the current is typically 220 volts.

In general different plug sockets are used to ensure people use the correct equipment relevant to their local current.

A good analogy is to imagine the pressure behind the flow of electrons in a circuit similar to water pressure in a building.

What does colour temperature mean?

Correlated Color Temperature(also known as CCT) describes the appearance of the light in degrees Kelvin. It is the measure of the colour of light emitted; it can be quite yellow (2700k) or very blue white (6500k). In the UK most home lamps are 2700k to 3500k.

Did you know? Some workshop prefer to use lamps with high colour temperatures. As 6000K gives more lumens than 2700K and give off a very white colour.

What does CRI mean?

CRI, or colour rendering index, measures the light quality of a light source as compared with sunlight (which is given the maximum CRI value of 100). The closer a light - sources CRI is to 100. The better its ability to show true colours. Lamps with a CRI of 85 - 90 are suited for venues such as art galleries, retail shops and photography where showing a good colour rendition is critical. Lamps intended for domestic use are able to have a lower CRI level (as low as 60). Which allows manufactures to produce products at lower price points whilst also providing suitable light. Remember: for the home, a higher CRI is not critical providing the optimum light level.
