+===== Measuring Illuminance =====
+It is not so simple as it can look, as you need sensor with proper spectral response as well as proper integration hemisphere.
+What is the good cheap lux meter that is more or less accurate (it is considered around +-10%)
+I suggest to get this one - https://www.aliexpress.com/af/lux-meter-lx1010b.html (with large white integration cover).
+It is far from perfect, but not very bad for many lights.
