Some tips to choose correctly the LED lights

The date is approaching: the next September 1, 2012 in fact, the traditional incandescent light bulbs with power ranging from 25 to 40 watts remained outstanding, will no longer be produced. How to choose the led lights for the house? With an eye on the price of course, but also considering the quality of the light and use in their environments.

While it is easier to refer to classes of energy efficiency, luminous flux (lumens) power (watts), average life in hours and luminous efficiency (lumens / watt), on the other hand we have the color temperature (K ) that can be warm white, neutral or cold (with shades of red, blue, green and yellow) and color rendering index (Ra or IRC). It was in the latter we have to pay attention if we are to illuminate the space where we spend a lot of time, especially for read or write, in this case, in fact, the index should not be less than 85.

Speech in part to the relationship between the power and the luminous efficiency. If a single LED lamp has a very high value in terms of luminous efficiency (the beneficial relationship between per-watt and lumen output), fatigue instead to evenly illuminate an entire room, but it is ideal for small areas. You will then need to use more than one for environment and study 'strategically' positioning.
