Question: two 10-watt than a 20-watt light illuminating?

Answer:
same power the lights, in the same performance conditions, they are light-emitting efficiency should be the same, if using two 10W fluorescent lamps, and a 20W fluorescent lamp of a similar nature to compare, will certainly be 20W more than a feeling of light is because the same power of lights you installed it into two, and its source area will be relatively bigger, it will than the total power the same a lamp ( point source and the light side of the different nature) are bright.

Answer:
a 20W, and definitely better than two 10W light-emitting a little more efficiency, slightly higher prices at lower prices. Incandescent lamp, too, a 100W light bulb than 10 10W light bulb, although the power of the same, but there are differences in luminous efficiency.
