Why does the light of a bulb seem to be fading when sunlight is coming through window?

What is being observed in a situation where a light bulb seems less bright when the sun is shining through a window is based on the way the eye works. Let's take a moment and look at the issues.
When a light bulb is on, we see the light and our brain "assigns" a "brightness" to the lamp. If it's a bright, sunny day and the lamp is near a window, all bets are off. The voltage to the lamp is the same, and the lamp is still emitting all the light (photomic energy) that it has been. But the "extra" light from the sun that streams through the window will "overload" the eye to a certain extent. The light will not seem as bright, and it is all because of the way the eye works. It has nothing to do with the lamp.

Can you absorb Vitamin D through a window?
Vitamin D is formed in the skin by the action of light on the skin, particularly ultra-violet light. Sunlight or a tanning bed will provide the necessary light. Sunlight shining through a window will work, but the window glass will absorb a lot of the necessary untraviolet radiation, so it will be a diminished effect.
How is the inside of a car on a sunny day related to the greenhouse effect?
Heat gets transferred from the window of the car into it. There is so much heat coming in that there is no way the car can keep up with the heat coming in. Trapping the heat. Same thing happens with the green house effect.A:The way a greenhouse works is that the transparent glass is transparent to the wavelengths of the sunlight coming through it, but is not very transparent to the wavelengths of energy trying to radiate back through it. Since we do not see in those wavelengths, the glass looks transparent to us. That is true of a greenhouse where plants are being grown as well as a car with its glass windows. The sunlight coming through the windows pours through easily, but the hot interior of the car radiates the energy back out at a different wavelength where the glass is not transparent. Similarly the greenhouse effect keeps the sun's heat in our atmosphere, preventing it radiating out into space.
