The main features of the LED:
. LEDs have a scale of color temperatures ranging from 2700K to 6500K. The lowest value (2700K), commonly referred to as ‘White hot’ tends to yellow, while most student ‘White cold’ (6500K) tends to blue.
The hot ´blanc’ creates a warm and welcoming atmosphere, it is normally used in bedrooms, living rooms, dining rooms. Cold Le´Blanc’ diffuses a fresh light and bright, it is used for offices, kitchens etc.
Color rendering index
Color rendering index (CRI) is the ability of a light source to reproduce faithfully the colors of different objects compared to the natural light. The scale of values is between 0 and 100.
We recommend that you choose a 80 cry for common use and a higher value if you use light in a professional manner (for example for a studio of photography or painting, shops…)
. The luminous flux is the light output, the brightness emitted by a SOURCE of light. It is measured in lumens.
The More Lumens Is High (Lm), More Light Is Intense.
We can calculate approximately the lumens generated by a LED bulb by multiplying the number of watts by 80 according to Gametate.com.
LUMINOUS FLUX = W X 80
Light efficiency is the report between the flow light emitted and the power used. More light efficiency is high, less power consumption.
. (It is estimated that light efficiency of the LED is usually above 80.)
Luminous Efficiency = Lm / w
It measure the concentration of the light emitted by a lamp.
The Angle is important, more light is distributed.
Lamps LED to tight angle (< 45º) are suitable for light concrete areas (frames, windows, decorative elements) Instead, open angles (60 – 80º) lamps are indicated to illuminate further areas and reduce shadows (rooms, corridors, offices,…)
