A prototype of a low-cost phototherapy light system (LPLS) was deployed by\nthe Ateneo Innovation Center (AIC) at a public hospital in Metro Manila,\nPhilippines. It underwent clinical investigation for two years under the\nsupervision of licensed physicians in a public tertiary hospital. This paper\npresents the process of upgrading the LPLS in order to enhance capabilities and\nimprove efficiency yet remain affordable. The following features were added:\n(1) a visual and auditory monitoring system in order to remotely oversee the\ninfant from the nurse station; (2) an automation system that stores data about\nthe device's light intensity and bulb temperature and records ambient humidity;\n(3) an alarm system that activates the warning lights if sensor readings are in\ncritical level and if the bulbs need to be replaced; and (4) a time setting to\nmanually set the time of operation and automatically turn-off the device as\nprogrammed. The upgrades increased the system's cost but it remained cheaper\nthan the ones commercially available. For deployment in remote or off-grid\nhospitals, the system was equipped with a solar-powering provision.\n
