Multi-featured bulb cfl installer remover

Thesis (Bachelor of Technology major in Electrical Technology) -- University of Rizal System-Morong.

EXECUTIVE SUMMARY: This study aimed to develop a Multi-Featured Bulb/CFL Installer/Remover. It was conducted at the University of Rizal System Morong Campus during the school year 2016-2017. This study aimed to determine the acceptability of the project in terms of usefulness, durability, and safety and maintenance as well as the significant difference as evaluated by the experts and end-users. There were two groups of respondents who tested the acceptability of the project. The first group consisted of ten (10) electrical instructor/degree holders as the experts who have the knowledge, skills and understanding on the circuitry and operation of the device. The second group of respondents consisted of twenty (20) house owners as the end-users. As the acceptability of the device as perceived by the end-users and experts. It was found out that the device was accepted in terms of usefulness, durability, functionality, and safety and maintenance. In terms of usefulness of the project, it gained a weighted mean of 4.7 from experts and 4.8 from the 4.8 from end-users with a verbal interpretation of extremely accepted, got a mean difference of 0.1 with 28 as degree of freedom with .05 level of significant, got a computed t-value .37 was less than the tabulated t-value of 2.048, thus, the null hypothesis was accepted and found out not significant. In terms of durability of the project, it gained a weighted mean of 4.7 from experts and 4.6 from end-users with a verbal interpretation of extremely accepted, got a mean difference of 0.1 with 28 as degree of freedom with .05 level of significance, got a computed t-value .33 was less than the tabulated t-value of 2.048m thus, the null hypothesis was accepted and found out not significant. In terms of functionality of the project, it gained a weighted mean of 4.6 from experts and 4.8 from end-users with a verbal interpretation of extremely accepted, got a mean difference of 0.2 with 28 as degree of freedom with .05 level of significance, got a computed t-value .17 was less than tabulated t-value of 2.048, thus, the null hypothesis was accepted and found out not significant. In terms of safety and maintenance of the project, it gained a weighted mean of 4.7 from experts and 4.8 from end-users with a verbal interpretation of extremely accepted, got a mean difference of 0.1 with 28 as degree of freedom with .05 level of significance, got a computed t-value .38 was less than the tabulated t-value of 2.048, thus, the null hypothesis was accepted and found out not significant. Based from the result of gathered data, the researchers concluded that there was no significant difference on the level of acceptability of the Multi-Featured Bulb/CFl Installer/Remover as evaluated by the experts and end-users in terms of usefulness, durability, functionality, and safety and maintenance. Based from the result of findings and conclusions, the researchers recommended that the device can hold different size of Bulb, LED, and Fluorescent Lamp. It must have a bulb catcher incase if the bulb was fall from the bulb holder and lastly the battery must have its own proper battery case. Further study on the test of efficiency and effectiveness of the project should be made in order to determine the extent of its use. It was recommended that the Multi-Featured Bulb/CFL Installer/Remover should be used for ease and easy to remove/install a bulb from higher ceiling.
