Wife got in on the game, and suggested parchment paper as a diffuser, in a
"lamp-shade" configuration. I cut the bottom out of a plastic bottle,
covered it in parchment and taped it in place. Works great. Two LEDs
give off light like a 40-watt bult, which doesn't sound like much but in
the dark it is incredible. Lamp not sits on the shelf in the study,
waiting for the lights to go out. <shaking head> I married a smart
woman.

Lamp NOW sits on the shelf in the study...
"... waiting for the lights to go out" Sounds ominous! ;-) Beware, the bottomless bottle bites!
