Turn Off the Lights is an extension for the Chrome browser. At it's very basic, it mutes/shades the screen except for the portion where the video is actually playing. In the classroom, this is brilliant for hiding other videos, ads, etc. I personally use it for watching videos not in full screen or to change the effect of the video I'm watching. Below is a screencast showing some of the features of Turn Off the Lights.

A couple of things to note:
- It does not attach where many other extensions are. It actually shows up in the Omni bar (also known as the address bar). The lightbulb type icon will be there anytime you are on a webpage where it can be used. Generally that is going to be where there is a video of some sort.
- There are some GREAT shortcuts to know
Crtl + Shift + L to turn lights on/off
Alt + F8 restore default opacity
Alt + F9 save current opacity
Alt + F10 enable/disable eye protection
Alt + (Up arrow) increase opacity
Alt + (Down arrow) decrease opacity
