A good selection of Quality LED Light is proven to bring our the best colours and atmosphere for your home. Not only it could enhance the natural colours of the home, a quality LED Light would provide you with a longer durability and efficient light meaning you change them less often. Hence, a Quality LED light generally defines itself into two measurements:
- Colour Rendering Index (CRI)
- Efficiency – Lumens (lm) & Wattage
Colour Rendering Index
One of the quality of light measurement used now is Colour Rendering Index. It has a scale of 1-100 and most LEDs have CRI80 while better quality of light is CRI90. Natural outdoor light has a CRI of 100 and is used as the standard of comparison for any other light source.

The CRI of Philips LED lighting products is always higher than 80, close to the sun’s value. Colors are reflected truly and naturally. The illustrations above show how CRI can affect the appearance of color.
Efficiency – Lumens (lm) & Wattage
Lumens are the amount of light generated out from a particular light source while its wattage is the energy use of a light source. As a simple summary, a better efficient LED light produces more light with less wattage. Means better savings!
For an example: A Philips BrightComfort LED 10.5W Bulb generates 1000 Lumens which is an equivalent to an Incandescent Bulb 75W (or 7 times more energy!) to produce the same lumen output.
