To turn the light on you need to press a button near motion detector and hold it down for a few seconds. This needs to be just one when you want to activate the light.
Mounting hardware is included in the package. It is a very nice light even though it does not have my favorite mode of operation "On only when motion is detected" which uses less power and works better in New England climate as we don't always get long sunny days to fully recharge the battery.
You can find it on Amazon by following this link.
