### Comparison of PARSLAD Performance in Three Scenarios

Table 9: Energy consumption in three scenarios. Figure 7: Graph for Energy Consumption of 8 W LED Light Bulb in three scenarios. for both incandescent and LED bulbs. PARSLAD with 0.5 W LED reduces energy consumption by 35% in comparison to the base scenario. On comparing the smart and manually controlled scenario, energy consumption shoots up by 0.0003 KWh. Thus, the manually controlled scenario works better than PARSLAD for a 0.5 W LED light bulb. But this is surpassed and PARSLAD provides an improved solution when additional numbers of LED light bulbs are added, as shown in Table 11.  
Figures 5-7 clearly show the increased energy consumption at 7:00 pm to 8:00 pm when intrusion is perceived in the absence of the prescribed daylight distribution. This upsurge in the smart scenario is due to the power expended for the operation of device along with ON state of light bulb. The energy upshot meant for one hour is adjustable when bearing in mind the reduction of power consumption in the four hours instance of 60 W incandescent and 8 W LED light bulbs. Nevertheless, in the case of a 0.5 W LED bulb, the smart scenario consumes more energy during the monitored four hours. Thus, the number of light bulbs controlled by a PARSLAD device is increased for the purpose of demonstrating the efficiency of the device. The readings for three scenarios along with four energy comparison parameters are shown in Table 11 (energy consumption ratio of base scenario contrary to smart scenario (ECR\({}_{\text{BS}}\)), Energy consumption ratio of manually controlled scenario counter to smart scenario (ECR\({}_{\text{MS}}\)), relative energy saving ratio of base scenario contrary to smart scenario (RESR\({}_{\text{BS}}\)) and relative energy saving ratio of manually controlled scenario counter to smart scenario (RESR\({}_{\text{MS}}\))). ECR\({}_{\text{MS}}\) can be seen as above 100% and RESR\({}_{\text{MS}}\) as negative for 0.5 W LED light bulb for up to 8 light bulbs indicating a smart scenario for consumption of a larger volume of energy than manually controlled, but it is to be noted that in the manually controlled scenario, the light is in OFF state for two hours whereas, in a smart scenario, the PARSLAD is in ON state during the course of the four hours providing better lighting control and monitoring. The device turns out to be highly resourceful in large indoor and outdoor buildings which deploy many LED bulbs and high wattage consuming bulbs. The device is efficient for 0.5 W LED bulbs which has power consumption smaller than that for zero-watt incandescent light bulbs. Consequently, in LED light bulbs, the device is efficient even for miniscule power consumption commencing with 12 light bulbs. Though the system can be incorporated for both indoor and outdoor environments, slight tailoring of the illuminance threshold values and lighting power sources should be made to support environment-based precision activity. \begin{table}
