Mammoth Lighting PAR Meter and Spectrometer

Description

Full spectrum analysis from 380 to 780nm with 2nm resolution, touchscreen interface, and 24-hour battery life at a fraction of lab-grade cost.

The Mammoth Lighting M400 PAR Meter & Spectrometer is built for growers, researchers, and lighting professionals who demand accurate, real-world data. Featuring a high-speed CPU and precision CCD sensor with a long focal cross asymmetric CT spectroscopy system, it delivers 2nm optical resolution and full-spectrum coverage from 380–780nm with accuracy within 5% of Apogee and $2000+ lab meters.

Unlike basic PAR meters that only measure PPFD, the M400 gives you a complete spectral profile, lux, irradiance, color temperature, CRI, chromaticity maps, and spectral distribution. Its lightweight all-aluminum body, 3.5″ HD touchscreen, and 24-hour battery life make it the most versatile field tool for analyzing grow light performance at scale.

Why it’s a smart investment for you

Most meters cost more while providing less data. The M400 PAR spectrometer offers a full lighting analysis suite, helping you dial in efficiency, spectrum control, and canopy performance without relying on guesswork. For professional cultivation, R&D, or commercial facility audits, it’s a fraction of the cost of lab-grade instruments.
