A Light in India

I enjoy stories like this.

- Iteration of a product to continuously improve the system while reducing costs.

- Realizing that a users choice can make the system more efficient (using lower wattage cfl bulbs) and acting on that.

- Second derivative waste product used to provide 500 additional jobs.

- Realizing that once you have a customer channel open they are susceptible to additional sales of a different nature (soaps, etc).

- Generic product improvements on the side to help manage core business (cheap smart card readers)

- Environmental goodness

Lean product development in a lean environment. Well played.
