He Replaced Incandescent Light Bulbs On Mercury Vapor Outdoor Yard Lights With Compact Fluorescent Light Bulbs
  Glen Schweppe, Syracuse, Neb.: Glen recently sent FARM SHOW photos of how he replaced the incandescent light bulbs on his old mercury vapor outdoor yard lights with compact fluorescent light bulbs (CFL), which are less costly to operate. He removes the transformers from the outdoor lights, leaving the crossbar that holds the shade on and leaving the electric eye on top. He drills 2 or 3 holes in the shade to accept snap-in porcelain lamp holders. Then he installs three 13-watt bulbs, which replace the yard light’s original three 60-watt bulbs.
  “We’ve replaced all our mercury vapor outdoor lights with CFL bulbs this way, with no problems. As a result we’ve saved a lot on our electric bill,” says Schweppe. “The CFL bulbs aren’t as bright as the original bulbs but they’re cheaper to operate. And if one bulb burns out there’ll still be two working lights. The shade comes with a round hole in the center, where I glue in a screen to keep bugs out.”
  Proper electrical rewiring is important, says Schweppe. “All the outdoor lights I’ve worked on have 3 wires coming out of the electric eye. On the wires coming in, I use the black as positive and hook it up to the other black wire on the electric eye. I hook white or negative to all white wires. I hook up the red wire from the electric eye to all black wires from the lamps.”
