First problem is that you cannot even reverse the camera so you can make a picture with the light which you are measuring ( how do you prove that the light is the one you are testing if you cannot place the phone on the illuminated surface?) . Second, you cannot create an emergency lighting certificate ( which I hoped it was in the app) . A completion certificate. No offence but the developer should work together with a competent professional to better understand the process of testing a light. I was so enthusiastic about this and i have paid the yearly subscription of £25 which i honestly regret. All the best ### 5/5 — Lux meter pro app *2025-04-18* Great app. Works well. Great for my electrical business working spotlights out and displaying to customers what the actual output is. I’ve also down loads the track my jobs app and in pair these two are amazing! Great work guys. ## Frequently asked questions about Lux Meter Pros ### What is Lux Meter Pros used for? Lux Meter Pros turns your iPhone into a professional light testing toolkit.
