We all want more light in our lives. But how much is too much? And how much is not enough? That's where Photometer PRO comes in.

Our lux light measure app - Photometer PRO - helps you measure the brightness of your environment so that you can get the right amount of light for every situation.

WHO CAN BENEFIT from our lux light measure app?

Whether you're a construction worker trying to compare different light levels after switching out your Halogen bulbs for LEDs, or just a flower hobbyist who wants to make sure each of your plants gets exactly the right amount of light, our lux light measure app - Photometer PRO - has got you covered. It even helps biology teachers practice photosynthesis!

✅INCREASE YOUR PRODUCTIVITY: whether you are a lighting designer, architect, electrician or just working from your home office - you can use the app to measure light levels and optimize lighting conditions, increasing productivity and enhancing the visual appeal of your projects

✅IMPROVE YOUR PLANT'S GROWTH: whether you are a horticulturist, greenhouse owner, or just a millennial (as we are!) who loves a little jungle in your home - you can use the app's PPFD calculator to determine the optimal light levels for plant growth, helping them create ideal growing conditions

✅SAVE THE ENERGY: our lux light measure app - Photometer PRO - helps homeowners, business owners, and lighting professionals select the right light bulbs and lighting fixtures, reducing energy consumption and promoting sustainable living
