Solar Lamps

Solar lamp is an argand lamp.  It greatly improved on the home lighting oil lamp of the day by producing a light equivalent to about 6 to 10 candles. The lamp quickly displaced all other varieties of oil lamps and were manufactured in a great variety of decorative forms. They were somewhat more costly than the old oil lamps because of their increased complexity, so they were adopted first by the well-to-do, but soon spread to the middle class and eventually the less well-off as well.
