LED streetlights tends to be very slim, but where their drivers installed?
The LEDs is still not bright and energy efficient efficient enough to light streets.
The two LED test lanterns in Shahar Haalia neighborhood in Haifa were also very slim like these lanterns, and they are producted the same amout of light as a street light with a 125W MV /DX lamp.
The optics provide illumination to both sides and front and back very evenly. The tilt is to cut off the verge and provide some light to the far side of the street. The drivers are quite small, as they provide DC current to the modules, and can be made thin and able to fit in the housing.
Update! Caltrans, the California highway department, approved the statewide conversion of HPS lights to LED. They say it will take 5-10 years. However they were supposed to start installing this past July and I still see HPS going up in new construction.
I see HPS in new installations here. They're repalacing the Pawtucket River Bridge on I-95 next to the old Apex store and they're also planning to replace that maze of bridges in front of the Providence Place Mall known as the "Providence Viaduct". Interestingly, MH shoeboxes are currently beingused in the new Pawtucket River Bridge but they may be temporary since 400W HPS M-400 FCO on davits are installed on the rebuilt section of I-95 right before the bridge.
