I cane seem to find the lumen scale. ### 1/5 — Light meter measure illuminosity *2020-08-22* Spent 1/2 wasting my time trying to get this paid app to work. Went to sent message to developer.

Bonne application ### 5/5 — Название *2016-09-25* Самое главное рисует разницу, можно сравнивать различное освещение. ### 5/5 — Excellent product! *2016-09-14, version 2.2* I bought this for my grow room and it is accurate AF! Just as good as a $80 machine.
