What are the specificities of market entry strategies in a developing country? It is primarily to understand the impact of high tech products such as energy efficient bulbs in developing countries by taking the aspects into consideration. This research is discussed only to understand the market strategies and entry barriers of energy efficient manufacturers, not to measure the effect. Therefore, the next step should be to examine the effect of the barriers discussed in this research. I am grateful to the following people without whose valuable contribution this research would not have been completed with success. Firstly, I would like to thank all those interviewed who gave us their valuable time and responded patiently to our emails. I am grateful for the valuable information you gave us that made this research fruitful. Thanks also to Sarah Philipson, the examiner, who nurtured us with her guidelines and high level of marketing knowledge. Finally, special thanks to my mother "Rehana Akhter" who motivated and supported me greatly throughout the research.
