Osram Dulux-D LED bulbs are the direct replacers for your traditional Dulux-D CFL bulbs with 2-pin sockets from 18 to 26 Watts. Dulux LED bulbs have a life span that is 3 times longer than conventional energy-saving bulbs and will last up to 15 years. In addition, you save up to 70% on your energy costs. The replacement is very simple because of the push-in socket and equal dimensions. Energy saving bulbs are often used in places where the lighting is constantly burning, such as: hallways, stairwells, public areas and warehouses. Make sure that the replacement wattage of the new lamp corresponds to the wattage of the old bulb. This prevents a difference in light output.
