    When the bulb costs more than the lamp…

    Every one of us at some time in our life bought one of these ‘torchiere’ lamps. Stands on the floor, about the same height as a person. They cost about $20 when I bought mine. They came with a 300W halogen bulb in a tube-style packaged called a ‘T3’ (tubular 3). Most (all?) are 118mm…
