These things are super bright and use about a quarter of the energy of their incandescent counterparts. This package is cheaper than anything I was able to find in any store, and they last forever. Also they don't get very hot, so the fire danger is super low. Really, these things are an investment. I went through my rental house and swapped the existing bulbs with these; I'll go back through when I leave and swap them back. They last forever so I'll take them wherever I move.
The biggest reason that I got these is because of a dirty, dingy entryway what gave a bad impression of the house. replacing the 40 watt with these, in addition to some other cleaning, did wonders.
