Nice alternative to the socket solution

I have several lights in my basement that I wanted to be motion sensor-ed. Not knowing about these bulbs, I bought something that screwed into the socket and then the lightbulb screwed in to that. They work great but are pricey. I came across these and thought I'd give them a whirl. They've been working great. "Only" 4 stars because the light is VERY white/harsh but bright and does the job in my garage.
