Standard 5mm LED.

The LED automatically applies gamma correction. This means that even a very short burst of current will result in some visible light, similar to how physical LEDs work, so you get more accurate simulation in the following cases:
analogWrite()with very small values (short duty cycle),
- LED scanning techniques such as Charlieplexing.
You can disable the gamma correction by setting the "gamma" attribute to "1.0". You can also choose a different gamma factor by setting this attribute to the desired value. The default gamma correction factor is 2.8.
The Gamma Correction Demo project shows the behavior of different gamma values: the LED on the left has the default gamma factor of 2.8, while the LED on the right has a gamma factor of 1.0. You can see how lower values of
analogWrite() look much brighter on the left LED.
