LED brightness<br />
4/7<br />
Brightness<br />
Because LED lighting uses so little energy the<br />
small amount of wattage consumed is not helpful<br />
in gauging the brightness of the light. Instead<br />
the industry refers to the lumen value to give an<br />
indication of brightness.<br />
The function of your lighting will guide you<br />
as to how many lumen you should be looking<br />
for. Typically, higher lumen products are more<br />
suitable for task lighting and lower lumen for<br />
accent lighting. However, choosing ambient light<br />
for a small room may require fewer lumen than<br />
for a large room. Similarly, low lumen for task<br />
lighting may be acceptable if multiple units are<br />
used simultaneously.<br />
RGB colour<br />
RGB LEDs cover the whole of the visible spectrum.<br />
From the brightest daylight through to a warm<br />
candle glow. They can also create a specific colour,<br />
using a mixture of red, green and blue light.<br />
Dimming<br />
Most of the lighting in this book is dimmable. This<br />
creates incredible lighting flexibility, changing the<br />
mood and function of a room instantly.<br />
Efficiency<br />
Because LEDs are 90% more energy efficient<br />
and can have a life of up to 25 years 1 , LED<br />
lighting will make a notable difference to your<br />
power consumption and environmental impact.<br />
Your guide to brightness in this book<br />
In the front part of this brochure we show the indicative brightness of a<br />
product through the use of a visual scale, shown here. If you want to know the<br />
exact lumen of a product it can be found in the technical guide.<br />
When you are looking at the brightness of a product it's useful to bear in<br />
mind that cool white tones are generally brighter than warm white tones.<br />
