Check out the map showing tornado alley in the U. S. During the winter of 2017, massive tornadoes occurred in the states of Alabama
and Georgia, two states that ARE NOT in tornado alley. If the conditfons for a tornado are predictable, how could these tornadoes
have formed in these two states?

i belive it is water

on passing the small ampere of electric current through the tube made of ar and hg of cfl generates uv rays which excites the fluorescent and thus emits the high radiation by consumption of just 5- 12 w in comparison to incandescent light which requires more power such as around 40 - 55 w to lighten.

moreover the life span of fluorescent or cfl is around 8000 h whereas the life span of incandescent is around 1200 h

hence, the building installed with incandescent lights bears more electricity bill.
