The STANBOW C37 LED bulb of 5 W is specially designed to replace the conventional 40 W halogen bulb. It consumes only a fraction of the energy needed by conventional halogen bulbs, which can save up to 90% on the electricity bill. This LED bulb has a long lifespan of 25,000 hours, which means it does not need to be replaced in the next ten years with normal daily use of 6 hours per day. In addition, it is environmentally friendly and safe for your family, as it does not contain lead, mercury, or emit UV or IR radiation. It provides instant lighting and high color reproduction, making it ideal for museums, exhibition halls, theaters, and dressing rooms.
