Museums must balance preservation with accessibility, yet lighting strategies for low-vision visitors in Indonesia remain underexplored. This study investigates the Jakarta History Museum through literature review, observational analysis, and calibrated lux meter measurements. Findings reveal that suboptimal illuminance and glare hinder accessibility, underscoring the need for layered lighting approaches integrating ambient, task, and accent illumination. These strategies enhance legibility, spatial perception, and visitor inclusivity while safeguarding artefacts. The study contributes to inclusive design discourse in Southeast Asia and calls for future research on adaptive technologies to optimise perceptual experiences under varying lighting conditions. © 2025 by MIP
