Using a Lux Meter to Quantify Light
There are many ways to describe light. Let us count some of the ways: “dim,” “hazy,” “bright,” “blinding,” “searing.” In addition to the descriptive terms, technical terms exist, too. “Candlepower,” “lumens,” “raw lumens,” and “foot-candles” are all terms common in the lighting world. The trouble is there’s little uniformity in all of these measurements. What the lighting world needs is a single standard by which lighting power can be judged. We may have found it. It’s called “lux.”
The term lux is a contraction of “luminous flux.” It’s a measure of intensity. One lux is defined as 1 lumen per square meter. Two lux is two lumens hitting that same square meter. Still confused? No worries. We picked up a lux meter and took some baseline readings.
Why worry about lux? Off-road lighting is often the difference between safety and danger after the sun sets. If you can’t see obstacles, you can’t avoid them. We’ve got an off-road LED light story in the works, where we’ll be taking lux readings, as well as showing the real-world light patterns projected. For now, take a look at our lux meter.
