 Sponsoring organizations identified and working connections established to test prototypes and get user feedback  Alpha prototype construction complete  Current power module design fails under high power loading  Circuit failure necessitates altered design to work under all conditions  Current light module functional and is capable of 0.8W operation  LED driver limits output power and as such the desired light is not currently possible  Field testing on hold until a working power module can be provided

Life Cycle assessment completed in SimaPro Proposed LED lighting system consists of 1 light module and 1/20 of a power module Proposed system has less than 3% of negative environmental effects of the currently used kerosene lamps This is largely due to the refining, shipping, and burning of kerosene

 Given the state of the project, it has not been possible to prove the product’s compliance with all engineering specifications  Two main areas were identified for testing  Discharge duration – to determine the battery life per charge  Light intensity and distribution  Additional testing was done to:  Characterize the power generator at various speeds  Determine the operational temperature of the LED at maximum power  Determine exterior temperature of light module  Determine if the light module needs additional shock protection

When used as a reading lamp (on the stand) the light provided by the alpha prototype light module follows the distribution below Light close to the center of the lamp is more than sufficient for reading Further out, the light is still better than current kerosene lamps but is not as useful as it could be

Light module was monitored throughout a complete discharge cycle. Special interest was paid to the voltage supplied by the batteries and the power supplied to the LED LED Driver requires 3.4 V for operation System shuts down when batteries drop to 3.4 V Power supplied remained fairly constant throughout the discharge cycle

SUCCESSES  Established a working relationship with two non-profit organizations with focus in Haiti  Established the base technology for the light and power modules  Base light module technology is a significant improvement over current kerosene lighting  Design meets most specs  Functioned effectively as a team throughout the course of the project FAILURES  Power module is not fully functional  Light module does not perform as highly as anticipated  Unable to send the alpha prototypes to Haiti for field testing  Unable to complete testing with system to determine compliance with specifications

Suggestions for future work in the product line  Solve issues with power module – protect module from over- current due to higher input  Increasing lighting levels – LED driver limits light levels but it would be beneficial if the module could produce more light  Send fully functional system (lights and power module) to Haiti for field testing  Revise design of both modules based on the results of field testing and feedback provided by the end users
