Last year I got an Alberta spruce to put on the table. I stuck it in the ground early spring. It's up on the hill at the top of the remains of my fallen oak. I bought some solar powered lights with the intention of lighting it, and that's what I did yesterday. I hooked the lights up last week, and turned them on yesterday. Since it's only 1.5' high, it's kinda extra lit. There's more lights than necessary, but it looks good. I can see it from the house, and it's the only thing with lights up there. The lights are pretty dim by morning, but they kept going through the night. It turns off, then charges during the day. Best $10 I've spent in awhile, and I have another string/controller I haven't used yet.
edit:
Just looked and they're dim now. I guess they don't get enough power during the day to last through the night. 5 hours isn't bad though. Still happy with them :^)
