Lumu Power

The Lumu Power is without any doubt the most full featured light meter I have ever owned. It’s tiny, it weighs hardly anything, it manages to offer a feature set that expands way beyond what most will ever need from such a device – certainly beyond what I need – yet it does all this for significantly less cash than any other device (or combination of devices) on the market. So how does it do it, and what’s the catch?
