This research paper examines the use of solar-powered daylight sensor lamps to enhance
energy efficiency and sustainability in urban areas, focusing on Barangay 743, Zone 80,
District 5, Malate, Manila. These lamps utilize renewable solar energy, reducing fossil fuel
consumption and carbon emissions. The study highlights the ecological benefits, energy
efficiency, technological aspects, and practical applications of these lamps in outdoor
lighting. The lamps incorporate daylight sensors that automatically deactivate during
daylight, minimizing energy consumption and operational costs. The paper addresses the

high electricity costs of conventional street lighting and details the fabrication of solar-
powered lights with components like weather-resistant lamps, charge controllers, inverters,

batteries, photo-light sensors, THHN 12 wires, and circuit breakers. The study includes a
proposed wiring diagram, prototype manufacturing, assessment, and experimental testing.
It evaluates the effectiveness and efficiency of the lamps in improving visibility, safety,
and user satisfaction. The lamps were strategically placed throughout the community and
tested for lighting effectiveness, performance, reliability, impact on community safety, and
user recommendations. The prototype received a mean score of 4.81 for functionality, 4.67
for aesthetics, 4.87 for workability, 5.00 for economy, 4.63 for safety, and 4.95 for
salability, all rated as "Excellent". The overall mean rating of 4.45 further confirmed the
system’s efficiency and reliability. These findings demonstrate the lamps' great
performance, reliability, and positive impact on community safety, along with high user
satisfaction and recommendation intentions. The lamps add value by providing practical
lighting solutions and enhancing safety benefits.
