This paper examines and analyzes improvement of structure of bulb, increase of luminous efficiency through application of reflector globe through aluminum coating and development of 60[W] basking neodymium lamp through optimum insertion ratio of krypton gas and nitrogen gas. The results of this development shows that the life of the lamp was 7,200 hours, and the luminous flux was 620[1m]. This brings in superior color temperature and superior color rendering index, which allows us to use that lamp for agricultural or general purpose.
