We do, and they suck!! Built the deck 6 years ago, and had issues with the lights from day 1. Wired them ourselves the first time, and thought we'd done something wrong when they started going out and/or flickering. Out of 10, we exchanged 6 at our supplier & still had the issues, tried to exchange more the next year and received no help. We had an electrician rewire from scratch, and still have the same issues. They are such a disappointment! We haven't looked for anything else to replace them either, and now just leave them turned off.

edit: ours are the post cap lights
