Solar Lighting for Rural & off-grid use

Tata Power has started selling its PV products through snapdeal.
Here is the link to a product I have known for a while.

It is a robust system and should last years.  The light is of the CFL type. The lamp is actually a 4 Pin PL lamp which is more efficient than the traditional 2 pin variety.

A 4-Pin lamp uses a pre-heat technology for firing the lamp, and hence has a much longer life.  It also prevents blackening of the lamp at the electrode ends.
