> Isn’t this expensive to run? It draws about 2 kWh per day (assuming 8h of usage), which costs about $0.30 at typical rates. This is comparable to one day of a modern fridge or one load of laundry. Power is cheap, folks!

But it will offset your other heat sources.

If you live alone, you can treat it like a room heater and lower the temperature for the rest of your home.

Since the bulb is radiating heat some degree of heat, you may be able to keep the temperature of the room you’re in lower without feeling cooler.

The fan is a bummer though.

Every few years some company/research lab will claim they have a technology that’ll simulate sunlight coming through a window, but it still isn’t something one can buy.

The moment we can buy eg a 3ft by 1ft panel that we can just mount on a wall and feels like an actual sunlit window for a few thousands dollars or so, interior design is likely going to get radically different.

(And that’s not to mention the sci-fi dream of a screen that can simulate a window looking out on any landscape, but these are probably way further out)

I'm extremely light sensitive, and so have built quite a few DIY solutions in order to alleviate my S-A-D symptoms.

One of my systems may have been a bit over powered and over used, as I developed what a doctor friend later diagnosed as "light induced hypomania", which was quite an experience.

Experiment at your own risk.

This is great to see, for I've been wondering lately why being outdoors is more pleasant (in clement weather) than indoors. Is it the unpredictability? the humidity? the noises? the sunlight?

In that same vein, I've wondered how to simulate outdoor conditions inside, especially something approximating more light, in part because I think a family-member is mildly susceptible to seasonal affective disorder. I can't wait to see what the author has to say.

i have seen articles about excessive blue light from led bulbs being bad for your long term eyesight i wonder if this has similar problems

Here's a good selection of research papers https://www.bioshumanlight.com/research/ . It seems like there might be some adverse effect due to the peak at the lower end of the blue spectrum. I'm waiting for the BIOS team to do a consumer product.
