Name: Three-watt energy-saving lamp Size: Diameter 3.5*Height 7.5cm/1.37x2.95in Weight: 26g Main material: plastic Three-watt energy-saving lamp is a low-power, high-efficiency lighting fixtures. It usually uses LED (Light Emitting Diode) as the light source, which can provide a brighter lighting effect, while only consuming a low amount of electricity. Compared with traditional incandescent or fluorescent lamps, three-watt energy-saving lamps have a higher energy-efficiency ratio, and are able to convert a larger percentage of electrical energy into light energy, reducing energy waste. As LEDs are characterized by long life, low energy consumption and environmental protection, three-watt energy-saving lamps also have a longer lifespan, usually up to tens of thousands of hours, eliminating the need for frequent bulb replacement. The brightness of three-watt energy-saving lamps can be applied to some lighting environments that require softer lighting, such as bedside lamps, desk lamps, night lights and so on. It can provide comfortable lighting effect, and will not produce glare or heat phenomenon, more safe and reliable. List: 1x Three Watt Energy Saving Lamp
