The Luminous Intensity Meter (LIM) is a portable, battery-powered meteorology instrument that measures light intensity emissions.

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.

With easy, click-and-drag constructioMany lights are too bright or too intense and are inherently unsafe for use at 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.

LIM Kit Includes

• Light Intensity Meter
• Remote Switch
• External Battery Pack
• Energizer L91 Ultimate Lithium, 1.5V Battery x4
• Carrying Case
• User Manual

LIM features a built-in laser range finder which measures range in feet or meters.  The device includes a 1/4″ – 20 threaded mount hole for tripod use.
