That is the closest design to what I thought of in my head. Add a prismatic refractor, and you have exactly what I was thinking of for future LED streetlights (though I'd prefer HIDs to stay!)
LED's themselves are not bad, but they should be used in proper designed fixtures with proper heatsinking. What mean flat lantern with LED's on the bottom and the body, shaped with fining on the top, should then serve as the heatsink. I know, such design look strange for many people here (judging about their comments), but i think it is only matter of tradition. Trying to keep "traditional look" would lead to troublesome b******s similar to CFL "incandescent retrofits"...
Agreed that Sticking to Conventional Designs for LED would lead to Trouble....as Cobraheads to me Were Made and Perfected for HID Lamps....as such...an LED Luminare will need to be created that makes an Optimum opperating enviroment for the LED's...also.....Such Language Medved!
In my opinion, I don't think LED is fit for streetlighting, I do think they're good for traffic lights though since they're more visible than those incandescent ones which are very difficult to see sometimes during the day especially if it's really sunny out.
LED's aren't bad you know, I agree with Medved, LED lighting isn't bad, you can get an LED as bright as a 400w HPS at like 100 or 150 watts.. or even less!
When you see an LED streetlight fixture, it looks ugly, but the reason is it has to look a certain way for it to last longer.
Also, lots of people don't even care for streetlights, (I mean people that aren't us) So pretty much if they create enough light and light the road well, It doesn't matter.
I would personally like to see LED Streetlights installed around Denver, there are none, all HPS. In fact I would like an LED Streetlight fixture myself.
LED's are not bad at all. I still prefer HID, but LEDs are getting better and better each day.
@Form 109 [induction]: I think induction is dead way. Their power coupling will never be as efficient as hot electrode concept, as they would always radiate copious amount of power as an electromagnetic field, what are at fist losses and as second troubles for radio communication (output from an efficient ballast would be very rich in harmonics, while filtering causes losses). And if you noticed, "classical" hot cathode concept fluorescent lamps appeared in the mean time with rated life 75+khours, what is the expected induction life as well. And fluorescent system would always cost far less...
@Form109 [language]: I'm sorry for it, i learned English only from it's use (method "jump to the water and try to survive"), so i'm not able to judge well, how much offensive some words are (hope you are referring to the now "starred" word, otherwise be more exact, please)

no way 100W 0f LEDs is going to replace a 400W hps
i'll Take HPS over LED's anyday.
@form109 yeah so would I
