LuxCam Light Meter

LuxCam turns your iPhone camera into a clean, fast light meter for everyday lighting checks. Estimate lux, color temperature (Kelvin), foot-candles, EV, plant PPFD/DLI, and camera exposure settings for desks, houseplants, rooms, workshops, and photo setups. LuxCam estimates illuminance and color warmth from camera exposure values, white-balance gains, and on-device image brightness. It is built for practical repeatable checks, not legal, safety, or certified lab measurements. For critical work, calibrate against a known light meter.
