Steve DiCasa from DiCasaFilm reviews the Lumu light meter:
In this video, I unbox and review the Lumu Light Meter that was graciously sent to me by LumuLabs.
The Lumu is a light meter that you plug into your smartphone. It reads the light and gives you the reading via an app. You can use either the “Lumu” app or other supported third party apps.
I was not paid to do this review, so it is an honest, real reaction. I also offer many of my suggestions to Lumu on how to improve the product.
