Light Up The World (LUTW) founded in 1997 by Dr. Dave Irvine-Halliday is a humanitarian initiative whose chief goal is to assist poor villagers in the developing world obtain a useful, healthy, safe, reliable, rugged, affordable and environmentally friendly White Light Emitting Diode (WLED) based form of home lighting.
This major goal is being achieved by the use of a safe, simple, healthy, affordable and reliable form of home lighting using low energy (1-Watt) White Light Emitting Diodes (WLED) Solid State Lighting (SSL). A child can read by the light of a single WLED which consumes less than 1 Watt. Thus, a rural home can be lit to a very useful level of illumination with ONE watt.
LUTW has demonstrated that the exceptionally low power consumption of WLED solid state lighting systems along with the simplicity of design and construction is ideally suited for the particular conditions that exist in the developing world. What is more, solid state lighting technology along with our processes can reorient development strategies toward the creation of enterprise, increased employment, enhanced income and gender equity, health and safety, and protection of the physical environment.
