Measuring the brightness of light is not a very straight-forward task. Currently, the most common measure of brightness is the lumen rating. Lumens replaced the old wattage-rating system because modern lights consume far less power and are much brighter.
A single lumen is the measure of energy that’s released from a light. Imagine putting a transparent bubble around a light bulb and being able to measure all of the energy that flows through the bubble –this is how lumens are measured.
At NEBO®, we don’t live in a bubble and we know that as lighting technology advances, so must the tools used to gauge the performance.
