“…There are a limited number of studies that analyze in more or less detail the polluting emissions or the cost associated with the use of fluorescent lamps in general compared to other light source technologies. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16] From the studies mentioned, it is difficult to extract any standards of use that enable CFLi emissions and costs to be made easily communicable to experts interested in illumination, much less to the final user.…”

This paper proposes a way to quantify the emissions of mercury (Hg) and C0 2 associated with the manufacture and operation of compact fluorescent lamps with integrated ballasts (CFLis), as well as the economic cost of using them under different operating cycles. The main purpose of this paper is to find simple criteria for reducing the polluting emissions under consideration and the economic cost of CFLi to a minimum. A lifetime model is proposed that allows the emissions and costs to be described as a function of degradation from turning CFLi on and their continuous operation. An idealized model of a CFLi is defined that combines characteristics stated by different manufacturers. In addition, two CFLi models representing poor-quality products are analyzed. It was found that the emissions and costs per unit of time of operation of the CFLi depend linearly on the number of times per unit of time it is turned on and the time of continuous operation. The optimal conditions (lowest emissions and costs) depend on the place of manufacture, the place of operation and the quality of the components of the lamp/ballast. Finally, it was also found that for each lamp, there are intervals when it is turned off during which emissions of pollutants and costs are identical regardless of how often the lamp is turned on or the time it remains on. For C0 2 emissions, the lamp must be off up to 5 minutes; for the cost, up to 7 minutes and for Hg emissions, up to 43 minutes. It is advisable not to turn on a CFLi sooner than 43 minutes from the last time it was turned off.

“…Starting from P, Q and D, the apparent power (S) is determined, which is the real power that must be supplied to the receiver for it to work. The expressions that allow us to calculate these powers are shown in Equations (2)- (5).…”

“…They also conclude that the savings are similar when CFLs are used, but they estimate that LED technology had (in 2015 when their study was published) more possibilities for improvement. Houri and Khoury [5] established that the replacement of incandescent lamps with CFLs in Lebanon would imply an 8.3% in consumption reduction, while Islam el al. [6] carried out a similar study in Kazakhstan but expanded it to the commercial/industrial sector and to outdoor lighting, in addition to residential lighting, documenting that energy savings are produced in all three sectors.…”

Analysis of the Real Energy Consumption of Energy Saving Lamps

Light emitting diode (LED) and compact fluorescent light (CFL) lamps are widely used because they are associated with low energy consumption and a reduced environmental impact. In the present paper, a study of the real consumption of these devices has been carried out. To do this, the active, reactive, distortion and apparent power and electrical efficiency for various lamps have been measured and calculated. The distortions produced in the network provoke the consumed energy to be in the order of 50–75% higher than that which appears in the commercial characteristics. This situation means that for its operation, it is necessary to generate and distribute an amount of energy much higher than that which is declared as the consumption of these lamps, and so far, this amount of energy is neither quantified nor invoiced. Additionally, groups of lamps have also been studied to check whether, when working together on the same network, there is a compensation phenomenon that reduces the negative effects of individual lamps. We have found that this compensation effect does not occur for the type of devices evaluated.

However, these studies do not present a general method that is applicable to a wide range of buildings and energy efficiency measures to select the technologies among all the available ones according to their energy consumption, energy cost, and CO 2 emission to optimize a given objective function subject to budgetary constraints.…”
