less than a second

The current professional definition, which dates back to the 1980s, states that lightning is an event that “lasts less than a second.”

a few milliseconds

That's the answer; lightning only lasts a few milliseconds, but your camera takes longer than that to scan the whole image, so in some frames the sky is only half-illuminated.

of a second

Lightning strikes, lasting less than a half-millionth of a second, often scorch the skin but don't cause internal burns.

3 months

The average lightning strike has enough energy to light a 100 watt bulb for 3 months.

just 0.01 to 0.1 seconds

A lightning strike lasts just 0.01 to 0.1 seconds, but just 0.01 to 0.1 seconds can contain a whopping 10 million volts of energy, according to Atrium Health.

up to 2 seconds

“A lightning strike made up of several discharges can last up to 2 seconds.

10 hours

Above the confluence of the observed regular storm activity of lightning in the clouds is almost 200 days a year, continuous lightning session lasts about 10 hours.

of 1-2 microseconds

Lightning strikes have an average lifespan of 1-2 microseconds.

2-3 miles

The average length of a lightning bolt is about 2-3 miles.

milliseconds

A typical lightning flash lasts for milliseconds but a typical Pikachu's electric discharge lasts for about 5-8 seconds.

100ms

Most camera shutter speeds last between 45-60ms, and the average lightning strike lasts about 100ms.

20 to 50 millionths of a second

Surges caused by lightning are very high power,but extremely short in duration, lasting only for 20 to 50 millionths of a second.

well in excess of 5 milliseconds

The duration of a typical lightning strike is well in excess of 5 milliseconds.

30 seconds

With a positive electrical charge, lightning travels between the negative base of a thunder cloud and the point of contact on Earth in about 30 seconds.

for several hundred milliseconds

Depending on the storm, lightning flashes can last for several hundred milliseconds and contain dozens of strokes.

from one nanosecond to several milliseconds

A lightning strike generally contains a series of pulses each having a duration of from one nanosecond to several milliseconds.

about 10 milliseconds, or 10,000,000 nanoseconds

By comparison, a typical lightning flash lasts about 10 milliseconds, or 10,000,000 nanoseconds.

to a 1,000 times longer (still only a few 10ths of a second)

However, about 5 – 10% of lightning strokes are different; they can last up to a 1,000 times longer (still only a few 10ths of a second), transfer so much electric charge that lightning protection measures are overcome, or they can generate significantly more heat and are far more likely to cause fires or other extreme heat-related damage.

a matter (thousandths of a second of a few tens of milliseconds

The difference in those numbers arises from the fact that a lightning strike only lasts a matter of a few tens of milliseconds (thousandths of a second).

three hours

The lightning strikes went on for like three hours.
