High Pressure Sodium (HPS) lamps are known for what characteristic?

Very short life
Low efficiency
High efficiency
Difficult to install

The correct answer is: High efficiency

High Pressure Sodium (HPS) lamps are recognized for their high efficiency in converting electricity into visible light, which makes them a popular choice for outdoor and street lighting applications. This efficiency is due to the lamp's design and the properties of the gas used within it, allowing it to produce a significant amount of lumens for each watt of energy consumed. The high efficacy of HPS lamps results in reduced energy consumption compared to other lighting options, leading to lower energy costs over time. This characteristic is particularly valuable for commercial applications where lighting plays a crucial role in safety and visibility. In contrast, other options presented highlight characteristics commonly associated with HPS lamps that do not align with their primary efficiency focus. Therefore, understanding the high efficiency of HPS lamps is key for both environmentally conscious selection and cost management in lighting design.
