There is a bit of difference in readings from various light sources but it read an old skool incandescent in a white room at 5000k and a supposed warm white cfl at 5500k - not even close. This is on an iPhone 4 if it makes any difference. Putting one star so it doesnt show as unevaluated, maybe more people will read comments before buying... unlike me lol.
