The Amprobe LM-200LED light meter is a professional tester specifically designed to accurately measure light output from LED light sources. With lux or foot-candle user selectable units, the LM-200LED measures light with up to ±3% accuracy. The measurement range spans from 20 to 20,000 foot-candles or 200,000 lux. While measuring all visible ranges of the light source, this Amprobe light meter also features angled light cosine correction.

The Amprobe LM-200LED light meter uses a silicon photodiode and filter to ensure accurate measurements. Results are clearly displayed on a 2000-count, 3-1/2 digit LCD display. Other features of the LM-200LED include built-in memory with storage for up to 99 readings, data hold to freeze the reading on the digital display, and max recording to capture the highest light measurement.

The Amprobe LM-200LED light meter's light sensor wire extends up to approximately 5 feet (1.5 m) and measurements are taken according to JISC1609:1993 and CNS 5119 general A class specifications. Additionally, the LM-200LED's spectral response is close to CIE luminous spectral efficiency.
