I found that the "ping pong paddle" style bulbs were still a bit bright for over the beds especially with the light lens having a magnifier in the middle. so we flipped them over so the light has to reflect off the white back of the fixture that seems to turn the lights into a flood instead of a spot.
As for foil in the fixture I have found that you get better light dispersal from a white back ground the foil just seems to scatter instead of flood the light...if that makes sense?
But in the end its what ever gets you through the night. Pun intended
