In short: not good for testing flashlights.
Thanks, I haven't read it all yet but it looks interesting. It hadn't occurred to me about the incandescant fridge light, but car headlamps also came to mind.
Still not enough for calibration. This sensor is not able to give you CRI or correct duv values. It can estimate the CCT, though.
