Ask HN: Why are there so few “artificial sunlight”/“artificial window” products?
by stevage on Hacker News.
The demand for “natural light” in homes and offices is very high, and higher than the availability of actual daylight. And there seems to be a pretty feasible way to create a fake window (a light panel that mimics sunlight through a window), using LEDs and a fresnel lens. There’s no shortage of videos around showing how to DIY such a thing, such as https://www.youtube.com/watch?v=8JrqH2oOTK4 and https://www.youtube.com/watch?v=GDeEuzKXCH4 So, why can’t I find many such products for sale? There are a couple of high-end companies like https://www.coelux.com/, but where’s the mass market stuff? Is there an opportunity being overlooked here, or am I just missing something?
