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?
Lumu Light meter
I’ve been ogling the Lumu for a few years. I don’t know exactly when it came out, but I remember being profoundly impressed by it as a concept. An accessory light meter for the iPhone that works via the 3.5mm earphone/microphone socket. It doesn’t even need batteries of its own, clearly this is some sort of voodoo!
