No idea; the effect seems similar but I do prefer the real sunlight for some reason. The lamp has the advantage of being easier from a time-management perspective though; I don't actually have to stop working and so on to use it. But I don't think that attitude is conductive to point B; taking extra care with work-life balance, getting enough exercise and decompression and so on, so I have a low threshold of just dropping what I'm doing and taking a break in the daylight :)
