This document describes the design work of an LED replacement for uorescent tubes that is both more energy ecient and does not contain mercury. The replacement should be a retro t which means that it can be mounted in the xtures of ordinary uorescent tubes without modi cation of the xture. The replacement is aimed to replace the T5 and T8 types of uorescent tubes. The document describes the theory behind the magnetic and electronic ballast and pitfalls in driving electronic devices using those ballasts. The selection process for the components used is described as well as the diculties encountered in the designing. The methods used for making measurements are also described. The prototype made in this project have a power output of about 5W and shows an energy conversion eciency of over 90 %.
