DID YOU KNOW THAT (Incandescent lamps)

  The use of E27 and E14 incandescent lighting is being discontinued. By the end of 2012 the production of this type of lighting will end.

  The solution involves the use of compact fluorescent bulbs or LED.

   One of the mistakes I see being done on a daily basis (for lack of information) is the way toconvert the power of incandescent to LED or compact fluorescent.

   Because about 80% of the power of the lamp bulb is transformed into heat and not into light, we can say that only 20% of the power is reflected into light.

   Theoretically, taking an incandescent 60W, 12W is only translated into light and heat in the remaining 48W. If we had a light that does not transform the electricity into heat (with a recovery of 100% light-electricity) it has enough to 12W!

   Both LED and compact fluorescent have the advantage of having a low percentage of electricity-heat transformation so the value of both, to replace this bulb, is a value slightly greater than 12W. A LED was recommended 13 to 14W and compact fluorescent a 16 to 18W as well.

   It's for another day the question of "color temperature" (have you noticed that for the same type of lamp,  one has a yellowish tinge, and some other lighter tone or cold tone) and the "lumens" (international unit that measures the light intensity and serves as a reference to compare different lamps relative to produce light).

   Regards.
