Colour Temperature - Colour temperature indicates how “warm” or “cool” the light emitted will appear, indicated by the correlated colour temperature (CCT). A CCT of 2700-3000K indicates a warm appearing lamp which are predominantly used in domestic settings. Cooler appearing lamps tend to have a CCT of 4000K and are more suited for offices and retail environments.
CRI - CRI stands for colour rendering index, CRI is the measure of how well a light source can accurately show the correct colour of an object. Colours can be distorted and mistaken for one another by lamps with poor CRI . A lamp with a higher CRI out of 100 is more likely to accurately show an objects true colour.
CE Mark - Standing for Communaté Européene, the CE mark is the symbol that must be stamped on products using a power source for them to be sold legally in the European Economic Area. The symbol confirms a manufacturers products comply with all relevant EU legislation.
Circuit watts - Circuit watts (W) stands for the amount of watts that are required to power a complete circuit, rather than just a single luminaire.
kWh - kWh is a unit of energy (kilowatt-hour) which equals 1,000 watts-hour. For example a 1,000W device uses a kWh in one hour - or a 1W device would use a kWh in 1,000 hours. This unit of measure is how an electricity bill is calculated.
Constant current driver - Constant current drivers are electronic components that are used with LED luminaires. Their purpose is to maintain a constant current to the LED’s. Drivers can be built into the luminaire or mounted remotely, and they often incorporate other functions such as dimming.
Lux - Lux is the measure of how much luminous flux (lumens) is spread over a given area (square metres), meaning it shows how much light is projected on to a surface.
