Very low (virtually none) even though we use a little more power than that.

What is the LUMINOSITY of the human eye?

The luminosity of the human eye is not a fixed value, as it varies based on lighting conditions and individual sensitivity. However, the eye is most responsive to light intensities ranging from about 10^-6 to 10^3 lux. In terms of brightness perception, the human eye can detect light levels as low as 1 photon under optimal conditions. Overall, the eye's ability to perceive light is highly adaptable, allowing humans to see in a wide range of environments.

What is the luminosity of the night sky. How much light do the stars produce relative to us compared to the sun?

The luminosity of stars varies quite a bit. Most stars (about 85-90% of them) emit less light than our Sun, while a few very massive stars emit, in extreme cases, over a million times as much light (or more precisely: total radiation) than our Sun.

How do astronomers measure stellar luminosity?

The reference that astronomers use to compare the luminosity of other stars is the sun's luminosity. The luminosity is denoted in multiples of the sun's luminosity. For example, the luminosity of the star Sirius is 25 times the luminosity of the sun.


What percentage of energy does an energy saving bulb save compared to an ordinary bulb?

It varies, depending on the specific model, but an energy-saving (fluorescent) light bulb should save at least half the energy, for the same luminosity, compared to the old-fashioned incandescent light bulbs. The incandescent light bulbs ought to be outlawed, except for specific purposes where the heat they generate is actually needed.


What is the color and the luminosity of 51 pegasi?

51 Pegasi is a G-type main-sequence star, similar to our Sun, and it has a yellowish-white color. Its luminosity is approximately 0.95 times that of the Sun, indicating it emits slightly less light. This makes it a relatively bright star in its vicinity, but not exceptionally luminous compared to other stars in the galaxy.
