A compact fluorescent lamp (CFL), also known as a compact fluorescent light or energy saving light (or less commonly as a compact fluorescent tube), is a type of fluorescent lamp. Many CFLs are designed to replace an incandescent lamp and can fit into most existing light fixtures formerly used for incandescent. Compared to general service incandescent lamps giving the same amount of visible light, CFLs use less power and have a longer rated life. The solar DC CFLs are made by using special technique (Ballast) by which the bulbs of 220 volt capacity can be lit only by 12 volt. These lights are different from other lights and give more illumination by using low electric energy and are also more durable than the other ones. It only requires 12 Volt DC. Lasersun Energy Pvt. Ltd. supplies 12V/7W and 12V/5W DC CFLs.
