"To me, lighting really sets the mood for a room. A 40 watt bulb in a cheap lamp is the same as a 40 watt bulb in an expensive one"

Edward Walker is recommending that the cost or quality of a lamp does not necessarily affect the amount of light it produces. He thinks that the lighting in a room is more about the atmosphere and overall ambiance it creates. He keeps in mind that a low-cost lamp with a low wattage bulb can produce the same quantity of light as a more pricey lamp with the same wattage bulb. Therefore, he suggests that it is essential to think about the impact of the lighting on the mood of a space, rather than solely focusing on the appearance or cost of the fixture. Overall, Walker highlights the value of utilizing lighting to produce an inviting and comfy environment.
