Here's a article (http://ecmweb.com/iep/challenges-installing-leds-20100501/) that I found that talks about some of the issues involved with using LED lights.

If I am honest, I don't really like LEDs being used for general lighting. I prefer them as indicator/warning lights. ;)
I don't see the point in large outdoor projects using LEDs requiring computer hookup. What happened to the good old timer/photocell/lightswitch to control lights? In my experience, I have been under LED lighting and found it to feel a bit dull and depressing.

I will agree on that for the outdoors lights so far...I prefer the Icetrons.....however an indoor light....depending on the circumstances, I found the this one to be AWESOME (http://www.galleryoflights.org/mb/gallery/displayimage.php?pos=-3821) for my bed light, display light, desk light and for very high ceiling recessed lights! The CFL I used to use over my bed was dull and terrible...no clean crisp light...the LED GE one I am using is very CRISP and has a most closer to incandescent color than most of other LED brands according to some people and what I have seen!

I've never seen one of them before. :o It actually looks kinda neat. I can only hope to see some come over here so I can try them out for myself. Those ones might be handy for my desk lamp. ;)

I do not like any "retrofit", as it involve many technical challenges to solve "impossible", what result into for me not acceptable compromises: Light quality, reliability, safety, cost, efficacy, to name few of them.
And why? Because somebody think "It would be costly to replace whole luminaire"? When the LED based retrofit lamp cost more then ten times the incandescent fixture they are intended for? Why i have to pay for "special phosphor coat technology to allow more even phosphor thickness on spiral shaped lamp", when on stright tube the way more even phosphor distribution is a piece of cake?
Don't tell me, then the purpose build decent LED lantern would cost more then the technically difficult E27 based LED lamp plus the incandescent light fixture, when with porpose build fixture many techical challenges simply do not exist (e.g. limitted space for LED heat dissipation)

Nevertheless, even if Haifa and Nesher streetlighting and Haifa port lighting aren't LEDs, their lighting controllers remotely hooked up to computers, that sends commands to turn on/off the lighting, and in the case of Haifa and its port, the time for switching on/off affected by an astronomical clock so they behave like a photocell.
