These are so super easy to install. These took about four hours to charge in direct sun and were lit up about 6-7 hours during the night before they started to fade in dimeness of light. The steak for the ground goes in easy but I recommend putting the solar pannel just somewhere out of stight as I don't really like the look of the steak in the ground. I hid mine in the rose bush where it was still able to get plenty of sunshine but not hideous out in plain stight. They are very easy for any project and I can't wait to buy more so I can do my entire barn with these.
