I never new light bulbs came in so many different kinds.  I guess I used to think there were just a few options, like bright, medium, and dim.  I went to the store the other day, though, and there were so, so many options!  The one I ended up going with was the gu10 bulb, which the salesperson told me a lot about.  I know more about wattage, life expectancy, energy usage, and color fastness than I ever even knew existed.  I’m just glad to be able to get some light that I like, that works well, and that is energy efficient to boot.
