Andrew Huberman uses a 10,000 lux white light source enriched in blue and green light as a sunlight substitute.

“I have a setup that I um constructed for myself that is basically a 10,000 Lux light these are available I don't have any relationship to 10,000 Lux light sources um those 10,000 Lux light sources tend to be short wavelength shifted they tend to be very blue they're white light but I don't think they have power across the visible spectrum I think they're they're very a red light and infrared diminish they tend to be um very blue and green light and enriched and it shows up as very bright white light so that's what um I put in front of me when I first wake up if the sun isn't out yet”
