RECHARGEABLE LIGHTINGOver 1 billion people in the world live without access to electricity, thelargest number of those being in sub-Saharan Africa and Southeast Asia.i Astable source of electricity for both home and facility births is essential tomaternal and newborn health and safety, which is often compromised whenlighting for midwifery tasks is inadequate. Rechargeable lighting affordsmedical personnel the ability to improve quality of care as well as detect andrespond to emergencies during births. iiLighting needed for health care differs from the type of lighting used forstandard household tasks, and at this time no study has been done toevaluate rechargeable lighting technology specifically in regard to maternalhealth requirements. However, recent research indicates that there are 14specific requirements for an off-grid, portable lighting product for maternalhealth applications.ii These 14 important characteristics are outlined in thefollowing summary of rechargeable lighting technologies. Thesecharacteristics include, but are not limited to, the light’s ability to providesecurity during the travel of the birth attendant at night, allowing freedom ofboth hands, minimization of shadows during medical procedures, and theability to be easily cleaned and disinfected. Further, the light’s spectralproperties are important for medical applications as it is essential that theselights provide high-quality, bright, and comfortable light that allows for truecolor illumination of wounds and other tissue. iii The correlated colortemperature, expressed in degrees Kelvin, that has been identified as themost appropriate for surgical and wound care applications is 5,000 – 6,000K,which is considered to be white light. iv However, there are many medical tasklights available that are 4,000 – 5,000K and can provide sufficient lighting fornon-surgical tasks.While there are many rechargeable lighting products on the market, thequality and performance of rechargeable lighting products varies widely. Therapid introduction of new rechargeable technologies on the market hasresulted in substandard performance, resulting in negative consumerperception of rechargeable lighting sources and a lowered demand for theseproducts. Factors impacting consumer perception include durability, cost,run time, and light performance. In response to these issues, severalorganizations, such as Lighting Africa, have emerged in an effort to regulatethe industry and improve the quality of off-grid lighting products.v2
