> For public lighting, sufficiently powerful LED streetlights exist. However, active or passive cooling should be added to them. It costs more (the whole unit is to be changed, well, not the mast, the head). Given the longevity of these lights, are they quickly amortized?
LED 500W = 60.000 lm, lifespan between 30000 and 50000 h. Some fluctuations in value depending on the ads and brands, of course.

The spacing between the axis of the bulb and the metal bottom should be within 2 to 3 cm.
Please note that the dimmer of these halogen lamps is not designed to vary the brightness of an LED.
