The Importance of Quality in Light Quality

Build quality and feature set are really important, especially once you use the light for any period of time. It needs to be a durable tool because if it falls apart, then you wasted your money. And then there's features like, can it be battery powered? Because otherwise you're going to be attached to a power outlet all the time. The most important one is SSI, which is the spectral similarity index - how close is this light to a known light source? That's the one that Curtis Judd uses. Above 80 is fantastic. 85 is like spectacular. Well, I'm all one.
