Choose bulb is not always a simple task. You should know decipher and understand the above information written on the packaging.
First, you must know that incandescent bulbs are banned from sale in Europe. Where the race for power was a determining factor, LED lights are not only dependent on this factor.It is better to dwell on the luminous flux rather than the wattage.
To choose your LED bulb, the following information must be sought on the label:
- The lifetime (LED solution is generally given 25 000 to 30 000 hours).
- The power (in watts).Generally the power of an LED solution is 6 to 8 times less than the equivalent incandescent.
- The luminous flux (in lumens).
- The luminous efficacy (expressed in lumens / W): over this figure, the higher the lighting is strong for the same power consumption.
- The Colour Rendering Index (CRI): this corresponds to the ability of the lamp to make the colors of the objects as closely as possible.IRC is based on daylight figure which represents the maximum, 100%. It is recommended not to go below 80% for quality lighting.
- Color temperature (in Kelvin) to about 3500 ° K light is called hot;it is considered neutral until 5300 ° K. The higher the value, the higher the lighting is cold and bluish.The lower it is, the more light pulls yellow and then said hot.
As energy saving lights defined on http://www.top-mba-universities.com/kitchen-and-house/led-lights-energy-saving-comparison/, the LED lights are certainly more expensive to purchase but can be a longtime investment. The average life of these lights can go up to 30 000 hours or 1 250 days of lighting so light is on 24/24.
