## Description

Photometer PRO is a powerful lux light meter and photometer designed for professionals, hobbyists, and educators. Measure brightness accurately in lux, foot-candles, and W/m², export readings to CSV, calibrate full sensor data, and track minimum/average/maximum light.

Additional features: Lux⇄Lumen and Lux⇄Candela converters, dark mode, multi-language support, instant performance, and a professional-ready UI — all aimed at providing accessible, precise light measurement and actionable insights.
