I like the idea of the light replicating seasonal cycles pretty accurately and have thought of finding some kind of light sensor that can keep the lighting in synch with the outside light. I can't imagine that the technology is all that expensive, because there's the night-lights with light sensors that turn on when the light goes below a certain level. For my purposes I just need the opposite response and the sensor needs to be in a different location (outside or at least by the window)
I think the pricey part is to get it gradual
