Lighting Products and Fixtures Design Dahom CFL Pingpong Energy Saving Lamp by Dahom Dahom CFL Pingpong when used in the home behaves and looks exactly like the traditional Thomas Edison incandescent bulb but without the heat generated and the energy used. In fact, it saves at least 65% of the energy used. Generally a 7W Dahom CFL Ping Pong can replace a 40W incandescent bulb, without compromising on its size. And in order to achieve the frosted look and feel, instead of using acid to frost the glass, Dahom cleverly uses a patented silicon sleeve. This not only delivers the frosted look, it also makes the light output more even and environmentally friendly.
