Thomas Edison and Joseph Swan did humankind a humongous favor when they invented what was probably the invention of the century—the humble light bulb. And now we have a lot of types of light bulbs available to us.

Two centuries later, these devices are still as relevant as the day they were created and have literally lit up many lives.

Though their relevance remains unchanged, light bulbs have far evolved from their original incandescent form. Today, bulbs exist in many shapes and forms, each one with its own levels of efficiency, way of functioning, light texture, light quality and functionality.

Given the aforementioned many shapes and forms (and throwing the many brands into the mix), something as simple as picking out a light bulb can quickly get not so simple.
