Onebyone, that seems strange that they only lasted a year. The lights I've been looking at online are all in one unit so of course I'd have to replace the entire thing. My sister's has had her lights for 4 years, leaves them on all day and turns them out at night. So far she hasn't had to replace any of them and they're quite bright but of course she had a electrician get them for her.
I'll be heading into town to check out Home Depot, Lowes and Menards with hopes I find something that will work for me.
Thanks all for your help.
