Yeah. but the interesting thing is that those things can actually be used to light up outdoor areas without even thinking about power. Costco had them on sale a while ago. $9.99 for box of 8. I thought they would be junk. So far they are really, really good. It surprised me, honestly.
But that is really a side issue.
I have a bunch of solar lights in a cluster outside. Last time our power went out I went out and got them for light! Voila!!!
