I've recently learned that Bioquip carries certain equipment that is not in their online catalog. For example, they make acrylic baffles for their light traps that will accomodate their standard 18" 15W UV lights (I just ordered two). If you call Bioquip, ask for Celia. She is very knowledgeable and helpful. -- J. Merrill Lynch Echo Valley Farm Watauga County, NC Elevation: 3,400 feet
