I seem to recall a part that was popular back when, called the "LDR-25", the letters standing for Light Dependent Resistor. And the numbers meaning that the thing could dissipate 25 watts? There were some projects with that thing running off of line voltage. Look in Popular Electronics "Solid State" or "Transistor Topics" (earlier) for these.
