There is an alternative that is free, going outside more, opening the blinds, taking a break mid day. I agree there is a niche for people that live at more extreme latitudes though. Not everyone has that as a good option. I factored in the sunlight and weather when deciding where to live It is a hard problem to solve technically. Getting collimated light in a compact space, not wasting a ton of energy while having high cri and the right color temp or emulating Rayleigh scattering. The higher end products are also pretty large.
