The ceiling light in the living room consists of 3 bulbs of 40W. It is yellow light. Recently I changed it to 3 white bulbs of 40W. The brand is Philips ( also available in OSRAM ). It costs $4.90 each. With white light, one cannot dim the lights, as such, I have taped down the dimmers.
The side lights at the dining room were changed too. I changed it from a 40W yellow bulb to a 60W yellow bulb. Each bulb costs $0.80.
