charlottegirl Call Karen over at Lantern & Scroll she can help you with this. We just replaced our outdated post light and she was great. All of their fixtures are USA made and really reasonably priced (mine was $325). www.lanternandscroll.com Cheers!
Consider adding a gas or electric lantern to a walkway. Its warm glow will make those winter days a lot less gloomy. Plus, they are fun to decorate for the holidays.
