A Light Bulb Moment.
Imagine your home or classroom without light. Light allows us to see, create a comfortable environment and be safe. Thomas Edison invented the incandescent light bulb nearly 120 years ago, and the bulb still works as it did when it was invented. Edmund Germer came along in the 1930's and invented the fluorescent bulb and large corporations have improved them. Certainly, both these inventions were important, but the fluorescent bulb has advantages over the incandescent light bulb in that the fluorescent bulb reduces energy consumption thus saving the consumer money. .
I literally had a light bulb moment while preparing to work on this English assignment. Upon entering my bedroom I flicked on the light switch and nothing happened. I stumbled across the room found the light fixture and removed the spent incandescent light bulb. After looking for the light bulb stash, and finding none, I knocked on my housemate's bedroom door and asked if he had a spare light bulb. Kevin searched his closet and found what resembled a light bulb but instead of the standard round glass shell, the new bulb looked like a glass tube that had been twisted several times and folded over. The bulb had the same screw base that fits a normal light bulb, allowing the socket designed for incandescent bulbs to fit properly. I said to him, " Kevin, the light bulb has changed since Thomas Edison's first light bulb." Kevin assured me that times had changed; what he had given me was a compact fluorescent bulb, a variation on the fluorescent tube. I thought to myself, "What goes on inside those white tubes is a mystery to me.".
Kevin, a junior high school science teacher informed me that the incandescent light bulb is an inefficient light source. Apparently, the standard light bulb works like it did when the bulb was invented. Inside a glass bulb electricity heats up a wire filament causing the filament to glow and give off light.
