Which of the following is a significant advantage of LED lighting?

The choice highlighting increased energy efficiency and a longer lifespan accurately represents a significant advantage of LED lighting. LEDs consume considerably less electricity than traditional incandescent bulbs, which leads to lower energy bills and a reduced carbon footprint. This efficiency is achieved because LED lights convert a larger portion of electricity into visible light rather than heat, as incandescent bulbs do.

Additionally, LEDs have a much longer operational life, often exceeding 25,000 hours, compared to incandescent bulbs that typically last only about 1,000 hours. This longevity reduces the need for frequent replacements, making LEDs not only more cost-effective in the long run but also more convenient by minimizing maintenance efforts and waste.

In contrast, the other options present drawbacks or characteristics that do not reflect the advantages of LED technology. For instance, higher initial costs can be a disadvantage for some consumers; however, this cost usually offsets over time through energy savings. Less brightness compared to incandescent bulbs is incorrect, as LEDs can provide equivalent or greater brightness levels. Lastly, difficulty in installation may apply to certain LED products, but many are designed for easy installation, thus not constituting a notable advantage.
