Lux Light Meter Pro
How do I calibrate Lux Light Meter Pro for accurate readings?
Open the app and follow the step-by-step calibration guide. Hold your iPhone up to a known light source and tap the calibration button; the process takes about two minutes and ensures reliable measurements for your plants.
Can I save and compare light readings at different times of day?
Yes, you can save readings with a date and time stamp. For example, you can take a measurement at 10 AM and another at 6 PM, and the app keeps them separate so you can easily compare them later.
Why is the screen too bright when I point it at a window, and how can I fix it?
The screen brightness increases to show the light reading clearly. Simply tap the screen to lock the current reading, then step away from the window to view it comfortably without squinting.
Does Lux Light Meter Pro have ads or hidden fees?
No, the app is completely free with no ads, pop-ups, or upgrade prompts. You get professional-grade light measurements without any cost, making it ideal for budget-conscious users.
How does Lux Light Meter Pro compare to a professional Sekonic light meter?
While a Sekonic meter costs hundreds of dollars, Lux Light Meter Pro provides comparable accuracy—within about 50 lux of a Sekonic reading—for free. It’s a practical alternative for indoor gardeners who need reliable measurements without the expense.
