HOBO Light Intensity Data Logger
Features and Specifications
What is Light Intensity?Light intensity is usually measured in lumens per square foot or lumens per square meter. The lumen is a measure of power, weighted by the responsivity of the eye. At 555 nm (yellow-green) one watt corresponds to 621 lumens. Moving away from this peak, the responsivity drops, and by 400 nm (violet) and 700 nm (infrared) the responsivity is down by about a factor of 100. Software and Accessories
