Bright Propane Lamps Provide Light Without Electricity
"Our model 450 is the result of eight years of research," says Samuel Schrock, owner of Midstate. "Most commercial propane-fired lamps are not bright enough. I knew the secret to bright light from low pressure gas sources was to get just the right mix of gas and air."
After trying a wide variety of tubes and fittings and introducing two earlier models to the market place, Schrock now has a lamp that will produce light that rivals the 100-watt bulb. It uses the Venturi effect, which recognizes that gas or liquid increases speed as the opening of a tube it is traveling through increases in diameter.
"As the gas moves through our Venturi design, the increase in speed pulls the correct amount of air to create the optimum mix of air and gas," explains Schrock.
The two earlier models are marketed mostly to Amish farmers, but Schrock anticipates a wider market for the 450. He recently had it certified by the American National Standards Institute. It's priced at $75 and is fueled with standard propane. With an adapter, it can be run off a 20-lb. or smaller propane bottle.
Schrock says the lamp's mantle will likely need replacing about once a month. Otherwise, the stainless steel, brass and aluminum fittings should not need maintenance.
