How many lumens is a full moon?

Illumination. The intensity of moonlight varies greatly depending on the lunar phase, but even the full Moon typically provides only about 0.05–0.1 lux illumination.

How bright is the Moon at night?

For example, the brightness of a full Moon is usually quoted at magnitude around –13, about 14 magnitudes or 400,000 times fainter than the Sun. (With a mean albedo, or reflectivity, of just 13\%, the Moon is actually as dark as worn asphalt.)

Is it brighter at night with a full moon?

When the Moon is full, the Earth is between the Sun and the Moon. So when you look at the Moon rising in the evening, the Sun has just set, behind your back. That means the side of the Moon facing Earth is fully illuminated. When you look up at night, the Moon will seem much brighter than Venus.

How much light does a full moon reflect?

What is a lumen moon?

A lumen is a measure of visible light and as such the Moon mostly reflects visible light from the Sun.

How bright is the Moon’s light?

The full moon shines with a magnitude of -12.7, but the sun is 14 magnitudes brighter, at -26.7. The ratio of brightness of the sun versus the moon amounts to a difference of 398,110 to 1.

Why does the moon glow at night?

The moon shines because its surface reflects light from the sun. And despite the fact that it sometimes seems to shine very brightly, the moon reflects only between 3 and 12 percent of the sunlight that hits it. The perceived brightness of the moon from Earth depends on where the moon is in its orbit around the planet.

Can you stargaze with a full moon?

The short answer is no, because a full moon is the brightest phase. In fact, the full moon is so bright that its glare drowns out most stars, making it a poor time for stargazing but a great time to view the moon itself.

Why is the moon light at night?

What is the lumen symbol?

lm
The lumen (symbol: lm) is the SI derived unit of luminous flux, a measure of the total quantity of visible light emitted by a source per unit of time.
