LUX Meter vs LuxCam Light Meter

LUX Meter is a private light meter for quick, practical illuminance checks with your iPhone camera. Measure ambient light in lux or foot-candles, compare rooms and work areas, check desk lighting, find brighter spots for plants, and see whether a space is too dim, comfortable, or bright enough for detailed tasks. Pick a target for your task — reading, office, kitchen, plants and more — and get instant "too dim / good / too bright" feedback as you move the phone. Simple and trustworthy: no account, no ads, no tracking, no photo storage. Features: - Lux and foot-candle readings - Lighting target presets with live in-range feedback - Live brightness scale with plain-language guidance - Hold mode to freeze a measurement - Session min, average and max - Calibration against one trusted lux value - Practical guide with common light levels - Paper-diffuser guidance for incident light - Private on-device camera metering Important: LUX Meter estimates illuminance from camera exposure. Great for quick checks, comparisons, and plant or room-light decisions. For regulated, safety-critical, or professional compliance measurements, use a certified lux 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.
