    The escalating demand for energy-efficient lighting solutions has propelled LED High Bay lights to the forefront of the lighting industry. However, ensuring product quality and reliability remains a critical challenge. This research delves into the application of Total Quality Management (TQM) and Six Sigma DMAIC methodologies to optimise the manufacturing process of LED High Bay lights within a Golf Country-based factory. The study aimed to identify and address the root causes of product defects, primarily focusing on electrical surge protection issues. Data were collected from various departments to analyse failure rates, customer complaints, and process inefficiencies. By employing tools such as flowcharts, fishbone diagrams, and statistical analysis, the research pinpointed the inadequate 4KV surge protection as a primary defect contributor. Implementing a 6KV surge protector for higher-wattage lights significantly reduced defect rates by 0.5%. This improvement led to decreased warranty claims, cost reductions, and enhanced product longevity, ultimately reinforcing the company's commitment to delivering high-quality products that exceed the customer's expectations. Such products need to be manufactured more often if companies want to survive in the Middle East as consumers will not settle for anything less. Refined production line layouts and automated key assembly stages alongside lean production principles are crucial to eliminate non-value activities. This can enhance the production of desired products in the companies. The findings underscore the efficacy of TQM and Six Sigma in driving operational excellence and customer satisfaction within the lighting industry.
