Description
LIDA (Lighting Inspection & Diagnostic Application) measures the quality of lighting sources at a professional level using your smartphone camera.
MEASUREMENT MODULES:
▸ Flicker Analysis
Measures the flicker frequency, percentage, and flicker index of LED and fluorescent lamps using the camera's rolling shutter. Provides risk assessment according to IEEE 1789-2015.
▸ Color Temperature (CCT)
Calculates the color temperature in Kelvin using the McCamy formula. Covers the full range from warm white to cool daylight.
▸ Light Intensity (Lux)
Estimates ambient light levels from camera EXIF data.
▸ Color Rendering Index (CRI)
Evaluates how accurately a light source renders colors on a 0-100 scale.
KEY FEATURES:
• Fully on-device — no internet connection required
• FFT-based real-time signal processing (C++ native engine)
• IEEE 1789-2015 risk assessment (Low / Moderate / High)
• 7 languages: English, Turkish, Spanish, Arabic, German, French, Russian
• Dark theme interface
WHO IS IT FOR:
• Lighting engineers and inspectors
• Electrical and electronics technicians
• Interior designers and lighting designers
• Health and safety professionals
• Anyone interested in lighting quality
