Luminous Intensity Meter
“A simple, safe and effective way to measure night lights in stadiums, parks, residential areas, and more to ensure compliance to light-pollution restrictions and safety specifications.”
The Luminous Intensity Meter (LIM) is a portable, battery-powered meteorology instrument that measures light intensity emmissions.
Designed, engineered and manufactured by Breault Research Organization (BRO), the LIM is capable of measuring several different photometric quantities. These quantities include: source intensity in candelas (candlepower), eye illuminance in footcandles, or lux and luminance in nits.
Many lights are too bright or too intense and are inherently unsafe for use at night. LIM is a simple, safe and effective way to measure night lights in stadiums, parks, residential areas — and more — to ensure the lights meet the safety specifications required.
