Led light bulbs are much brighter than incandescent or halogen bulbs of the same wattage, but led bulbs are not available in very high wattages. Thus, when replacing incandescent or halogen lamps with led lamps, more led lamps are often needed. For example, to replace one 100-watt incandescent bulb you may need two 5-watt or 6-watt led bulbs. Although you have more bulbs you are still using 85% less electricity.
