A new screw-in type fluorescent lamp has been developed to save energy in lighting. It is more efficient than traditional incandescent lamps, using less power and lasting longer. This lamp can be easily screwed into existing sockets without the need for special equipment. It provides the same brightness as a 60-watt incandescent lamp but only consumes 35 watts of power. By using this lamp instead of incandescent ones, approximately 26 liters of oil can be saved over its lifetime. The lamp is lightweight, comes in three colors, and is designed to be attractive and simple.
