Not mine, I find it on the YouTube:
I guess there is not much missing from what ever illuminated streets in the Czech republic in the 80's...

I agree. They look cool.  But definitely the one on the right reminds me of NEMA heads ANd yardblaster buckets

I hate LEDs in general lighting. There is an important factor in lighting that called "Reliability", which is often more important than energy efficiency, as the more reliable lamps, the least waste to be producted and the less lamps to be manufactured.
Today. the majority of LED lighting, have shorter life than incandescent lamps. This is because in this application, either the LEDs are overdriven to turn them into a point light sources of high brilliancy (LEDs aren't designed to be a point light source, like dishcarge lamps), and crowded to a small area to get the LED lamp/fixture/lantern smaller, resulting in a severe overheating (Worser in a low power 5mm regular LEDs, than with high power LEDs), and premature failure.
Also, there are also problems with the LEDs power supplies: Instead of an infinity life core and coil transformer (Similar to 12V halogen lamps) and only few components to transfer AC into DC and filter the flickering, they uses an electronic high frequency drivers, that are totally not different than a computer power supply unit. This results in the fixtures often blows before the LEDs themselves.
For me, fluorescent lamps on magnetic ballasts and mercury lamps, can have much longer life than LEDs, and are the real green choice.

Well that's your opinion, I see the success of LED lights 5 years from now.
