power saving street lighting solution needed

Dear Sirs,

We are looking for alternative to our existing sodium lamp based street lights in the form of more energy efficient LED Lamps.

Also we are looking at solar power as an alternative to the conventional electricity for lighting the lamps. As we belong from a place in India that is mostly sunny throughout the year but I am more worried about the cloudy days.

Also please provide us with the details of the carbon credits that will be earned with your products.

Please provide us your lighting solution at an affordable cost.

Our required quantity is around 400 Lamps.

Thank You,
