Flicker Safe: Test Light

FlickerSafe is a camera-based LED flicker tester for filmmakers, photographers, streamers, and event crews. Point your iPhone at a light to see its flicker frequency, modulation, and camera risk before you shoot. Use FlickerSafe when scouting venues, setting up a home studio, comparing LED panels, checking dimmer levels, or preparing a shoot where lighting needs to stay camera-safe. Key features: - Estimate dominant flicker frequency from camera luminance samples - Measure modulation depth and camera risk - Check common shutter speeds such as 1/50, 1/60, 1/100, and 1/120 - Get safer shutter-speed suggestions for the detected light - Save fixture measurements and history for later reference - Export production reports with FlickerSafe Pro FlickerSafe is designed as a practical field tool, not a laboratory instrument. Results depend on device camera capabilities, ambient light, fixture brightness, and how steadily the phone is held during capture.
