What technological solutions are demonstating promise for solving the lighting problem?
There are several innovations in lighting that promise provision of affordable, high quality lighting. These include recent advances in lighting technologies such as compact fluorescent lighting bulbs (CFLs) and light emitting diodes (LEDs). The rapid development of solid-state lighting technology over the past 10 years enables consumer product companies to incorporate LEDs into lighting systems which require less than a watt of power input, but which deliver useful light adequate for task lighting, lighting a living space, and/or reading. For example LED packages fewer than five watts deliver adequate light for night fishing and other substantial commercial applications such as night markets. Because of the low power inputs, LEDs can be packaged with low-cost battery power systems and even recharging systems based on photovoltaics, mechanical(hand) pumps, pico hydro, or any other mechanism for generating small amounts of power; these are similar to cell phone recharging stations which
