What are lumens?

A lumen is technically defined as one candela multiplied by one steradian. In layman’s terms, one lumen is equivalent to the light produced by one birthday candle from one foot away. To expand this idea, seeing 100 lumens is like standing one foot away from a cake with 100 birthday candles on it.

Lumens, unlike watts, are a direct measure of light output. Therefore, a larger lumen count means a brighter bulb.
