LEDs are known for their energy efficiency, which is one of their most significant advantages over traditional incandescent or halogen bulbs. When we say that LEDs consume less power, we mean that they convert a greater proportion of electrical energy into light rather than heat. This higher efficiency results in lower energy costs and reduced environmental impact due to decreased electricity consumption.

In contrast, traditional bulbs typically waste a significant amount of energy as heat rather than light. This inefficiency not only leads to higher electricity bills but also often requires additional energy used for cooling in spaces where these bulbs are employed. Thus, opting for LEDs contributes to conservation of energy resources and aligns with efforts towards sustainability.
