IMO neither of those would provide any good lighting for a deck. Post some pics of the house and deck area usually you will need more than just a couple of lights on a wall but without any more info who knows.

Thank you. I already have a flood light and small light by the dooor. the deck will be the size of the house, the furthest windows will be the sliding doors Thank you for your help.

What are you trying to do with the lighting? Light up the entire deck? Provide enough light to see the entry/exit to the door at night? Just aesthetics? That will make a huge difference in what light you will need. We recently installed a solar double-bulb security light on each corner of the back of a house and it lights up the whole deck (which is the length of the house). We installed a single-bulb light directly on the wall outside of the door and it provides enough light to illuminate the walkway.

Would you happen to have a picture?
