Esta Lámpara es Más Eficiente que los LED pero ¿Ya No Existe?

Hello! In this video, we explore a type of lamp that marked a turning point in the history of lighting: low-pressure sodium vapor lamps. What made them so special? Why were they the absolute kings of energy efficiency for decades, even comparable to today's LED technology? I'll tell you how they work, what their technical characteristics are, why they emit that distinctive orange light, and how they came to illuminate streets, tunnels, and highways around the world. We'll also talk about their role in the fight against light pollution and why they have been replaced, despite their impressive performance. In addition, we explore how their efficiency reached over 200 lumens per watt, a figure that even many LEDs still fail to achieve. If you're interested in the world of lighting, technology, and energy, you'll love this video. It's very important to credit the English-language video I used for this research, as I don't own a sodium vapor lamp:    • THIS LAMP SOXs! "Yellow" tech of bright me...   Without this original video, mine wouldn't be possible. 💡 Don't forget to subscribe if you want to see more content about lighting history, technology, and scientific trivia. 📸 Channel created by a photographer and lighting technician passionate about audiovisual outreach.    • THIS LAMP SOXs! "Yellow" tech of bright me...
