keywords: 

{'mercury': [0, 0, 2, 2], 'lights': [0, 0, 0, 6], 'lamps': [0, 0, 1, 5]}

The correct answer is option 1: 1 only.

Statement 1 states that LED-based lamps do not contain mercury. This statement is correct. Unlike other types of lamps, such as fluorescent lamps, LED-based lamps do not require mercury to function. This makes LED-based lamps a safer and more environmentally friendly option.

Statement 2 states that LED-based lamps cannot be used as street lights. This statement is incorrect. LED-based lamps are actually commonly used as street lights due to their energy efficiency, long lifespan, and directional lighting capabilities. LED street lights are known for their ability to provide bright and uniform lighting while consuming less energy compared to traditional lighting technologies.

In conclusion, LED-based lamps do not contain mercury, which is a positive attribute, and they can be used as street lights, debunking the second statement. Therefore, option 1, which states that only statement 1 is correct, is the correct answer.
