The spotlight should shine properly, but the length of the coffee-can does little to acceptably limit the angle of the spotlight. You’ll need to add an extra length of flashing to provide enough shield length. The longer the length of the shield, the smaller the angle of the light cast. The best material for the shield is aluminum flashing. You’ll find it in the roofing and insulation section of the hardware store. Thin rolls of flashing are widely and cheaply available (see figure 22-14). I’ve found that flashing with a width of 18” provides a good, fairly intense beam. Much wider flashing is available, however, if you need a narrow light angle. Unplug the electrical cord and remove the light bulb from the fixture so it won’t be damaged during the shield construction. Wrap a length of flashing around the coffee-can and mark it so there is approximately 1 overlap (see figure 22-15). Use tin snips to cut the proper length along the marked line. Wrap the flashing around the can making sure that end of the flashing extends a few inches beyond the top of the can. The can will act as structural support for the flashing while you use a wood screw to
