I love light bulbs! Before the electric light bulb, people at night used gas lamps (which were dangerous), fuel lamps (which were dangerous and dirty), and — for most of the time prior to the 20th century — candles (which also were dangerous and dirty).
Not only does the light bulb provide reliable and ample light, it does so without polluting our homes’, workplaces’, and play-places’ interiors. And being much safer than candles, fuel-burning lamps, or gas lamps, light bulbs are much less likely to ignite fires — fires that would burn down not only the buildings in which they started but also risk burning down surrounding buildings.
