Scientifically sound parameters for choosing a lamp are:
1. Energy consumption (watts), the well -known value showing power consumed by the lamp. In the incandescent lamps, the relationship between power and brightness of the light has been preserved. However, for LEDs or fluorescent lamps, this trend is not relevant. To buy such lamps, an online store of LED lamps is suitable, in which you can choose copies of the large assortment you are interested in.
