One of the frustrations in our "new" house is the number of different type light bulbs that are used thru out. My inventory of spare light bulbs in the 'old" house consisted of a 4-pack of 60 watt incandescent bulbs. Today, I am looking around to replace light bulbs in three different locations and all three are different type bulbs and all are more expensive than the standard bulb. I am too the point that I take the old light bulb to the store with me in order to get the right size base to fit the fixture.
So how many old people does it take to change a light bulb? - one to remove it and six to decide what kind of light bulb it is and to find that type of bulb - than hire someone to put it in.
