Los Angeles Times ran an article featuring Matthew Rolston on "How to light yourself at home".
One of his suggestions?
“Put a dimmer in every single light in your room — either the switch,
the wall or the cord,” he said, waving to the shelves.
If your lamp
doesn't have a built-in dimmer, the photographer said, you can add a $2
dimmer switch to the cord.
Even easier? Rolston loves a dimmer
attachment that screws into the bulb mount. Cost: $8. “This gives you
the ability to control the light without help from an electrician.”
