Background:
The regular street lights are primarily Sodium Vapor Lamps (orange color lighting) since the luminous efficacy (lumens/watt) of the lamp is the highest for sodium vapor lamp (>100lm/watt).
That is the primary reason Sodium vapor lamps were predominantly used for street lighting since the quantity of light is the highest with that lamp and the quality of the light for street lighting isn't critical. A typical Sodium vapor lamp consumes around 150 watts with additional 10-15 watts for the ballast.
Advent of LEDs:
With the technological advancements, the LEDs have gained popularity with lower power consumption and higher lifetime.
A typical 150 watt sodium vapor lamp can be replaced with close to 60 watt LED lamp (saving of more than 50%)
Energy Saving in Street Lighting:
The street lighting is controlled and operated by the local municipal corporations. Government of India under the aegis of EESL (Energy Efficiency Services Limited (http://eeslindia.org/Home.aspx)), an entity under Ministry of Power has started a program called Street Lighting National Program, wherein the Govt. is driving the faster implementation of LEDs for street lighting by the municipalities.
Accordingly, the municipal corporations are entrusted to replace the lighting with LED lights.
Now, due to the high initial investments required for installing LEDs, the municipal corporations are adopting a model called ESCO (Energy Service Companies) where the LED supplier installs the LED street lights and he is paid by the municipal corporations based on the savings achieved which is monitored monthly.
The faster implementation depends on a lot of factors like the funds and budget available with the Municipalities, the priorities of the Municipal corporations etc.
I have been personally involved in preparation of the Tender document for a municipality which was planning to implement LED street lighting on ESCO basis...!!
