What is a key characteristic of LED fixtures compared to traditional lamps?

LED fixtures are known for their energy efficiency, which translates to a significantly reduced electrical power requirement compared to traditional lamps. Traditional incandescent lamps and even some types of fluorescent lights consume much more electricity to achieve similar levels of brightness. In contrast, LED fixtures are designed to produce a greater amount of light using considerably less power, leading to both energy savings and reduced operational costs. This characteristic makes LEDs an attractive option for stagecraft, as it not only helps conserve energy but also minimizes heat output, which is beneficial in performance settings where overheating can be a concern.

Other options, such as higher heat output or greater weight, do not apply to LEDs; in fact, LEDs typically generate less heat and can be lighter than traditional lamps. While LEDs offer a wider range of color options, this is not their primary distinguishing characteristic compared to traditional lamps, which makes the reduction in electrical power requirement the most notable advantage.
