What type of lamp is known for being cooler and more efficient than halogen bulbs?

The type of lamp known for being cooler and more efficient than halogen bulbs is the LED lamp. LEDs, or Light Emitting Diodes, produce light through a process that generates very little heat compared to traditional lighting options like halogen. This higher efficiency means that a greater percentage of the electrical energy consumed by LEDs is converted into light rather than heat. As a result, LEDs not only help in lowering energy costs but also contribute to a cooler lighting solution, making them preferable in many applications where heat accumulation is a concern.

This efficiency in energy use allows for longer lifespan as well, with many LED bulbs lasting tens of thousands of hours, contributing to their growing popularity in both residential and commercial settings.

In contrast to LEDs, options like incandescent, fluorescent, and halogen lamps tend to generate more heat and can be less energy-efficient, making them less favorable choices in situations where energy conservation and cooler operation are a priority.
