Very disappointed. Light only travels about 6” down the deck post - doesn’t light up any of the deck but more importantly, they don’t shed any light on the stairs. These were to replace plastic bargain deck lights that hung for 8 years but the plastic was breaking down and shattering. These do not provide any of the lighting my plastic ones did. Even after a week in the sun charging! If you want to light up deck flooring or stairs, these will not do anything except light up a small part of your deck railing..... a very small part. I am planning to buy the dollar store plastic ones which I know will do the job. These look nice but provide no lighting on a deck or stairs. Should not be selling them as deck lights ..... perhaps more like deck railing accent lights.
