Wall Socket Lights

The wall socket night lights (Figure 22) are a good way to use unpaired giant clam shells in the 8- to 10-centimeter size range. They are easy to make and probably represent the most profitable product possible for unpaired shells in this size range.

Use shells that have been chemically bleached, acid dipped and lightly smoothed around the shell lip on a grinding wheel. Use the wheel to grind off a flat area near the base of the umbonal area of the shell. The ground-off area is then glued directly to the bulb fixture with a hot glue gun. With a little practice, an unskilled worker can turn out about 20 of these per hour. It's not a bad use of time considering the retail value of the lights.
