in this research, we calculated the cost of replacing the fluorescent lamps of the X-juice plant before and after the life span of it. The number of lamp was 6000 where we studied the advantages and disadvantages of this process and obtained excellent positive results. The study also focused on saving electricity consumption in terms of the quality of lighting and how to increase efficiency in public institutions such as hospitals and schools in order to reduce the burden on the public electricity company without affecting the level of efficiency required to operate lamps and electrical equipment used in the institution, the results shown that it is possible to provide electricity bill, and increase its reliability, by taking some technical measures in such facilities. We have noticed through the studies that the cost of the first case (11) months 76500 Libyan dinars. In the second case (11) months, the cost was 54,000 Libyan dinars. And these are the most important results we have obtained and is to provide an amount of 22500 Libyan dinars every year, or 29.4% with many advantages and the most important maintenance of transformers in the case of full stability in terms of withdrawal of current.
