This reserch aims to develop an interactive multimedia learning tool in the form of an e-module for the subject of Electrical Lighting Installation andLighting Design in the Electrical Engineering Education program at Undiksha University. The study addresses the issue of students lack of knowledge in determining proper lighting in a room. It follows a Reserch and Development (R&D) approach.The reserch employs statisticalanalysis techniques, specifically percentage analysis, to process data from content experts, media experts, and student trials. Questionnaires areused as data collection instrumens for content eexperts, media experts, and students. The reserch findings indicate a validation test result of 97.7% from content experts, qualifying as highly suitable, a validation test result of 92.85% from media experts, qualifying as highly suitable, a small group trial with 5 respondents achieving a 100% result, qualifying as highly suitable, and a large group trial with 17 respondents achievingan 86.02% result, also qualifying as highly suitable. The developed learning tool, an Interactive Multimedia Development based on e-module for Electrical Lighting Imstallation and Lighting Design in the Electrical Engineering Education program at Undiksha University.
