In the picture I posted--
--the bulbs are horizontal
--the frosted glass shade is below them
--there is no shade above them
--the ceiling is moderately dark (main reason why this room is hard to light)

So maybe my "test" should include a situation such as in a table lamp, where the bulb is upright and lights up the ceiling and walls. One thing I haven't done is to try it at night, when there is no outside light. To be truly "scientific," though, I would have to remove all the furniture and somehow take a picture of the floor, but how could I do that without blocking the light with my camera? Oh, well. I guess the main thing is whether we decide we like it in our house.
