Detailed Instructions: In this task, you are given a question and a context passage. You have to answer the question based on the given passage.
Q: What quality do incandescent lamps have less of that make them better than LEDs?, Context: Since LED efficacy is inversely proportional to operating temperature, LED technology is well suited for supermarket freezer lighting. Because LEDs produce less waste heat than incandescent lamps, their use in freezers can save on refrigeration costs as well. However, they may be more susceptible to frost and snow buildup than incandescent lamps, so some LED lighting systems have been designed with an added heating circuit. Additionally, research has developed heat sink technologies that will transfer heat produced within the junction to appropriate areas of the light fixture.
A:
susceptible to frost and snow buildup
