What does 300 hours mean? 300 hours from when you turn it on until you turn it off? 300 hours from the moment you install the battery? Some other variant of 300 hours?

300 hours of light burn time. Depending upon application, that could be quite a long time. I am tempted to buy one to put on my Ruger PC-9. The shake awake feature means that it can sit at the ready without the light on, then when I pick it up, it's ready.
