LAB ASSESSMENT REPORT
LIGHTING INTRODUCTION During this assignment student have to do a lab test for both acoustic and lighting and from the lab test of both acoustic and lighting they need to analyze the content of both and perform an good report base on the all the analyze data that been collected. The purpose of the lab assessment test are for the student to understand how to differentiate lighting in their deep properties.
THE OBJECTIVE The main objective of the lab test assessment are to allow the student to understand with the lighting such example of it colour, watts, rendering colour, an d etc. It for student to understand the technical specification of all the different light sources. During this lab assessment student will undergo several different of lighting and from there, they need to come with good sense of analyze of the lighting issues.

Lux meter Camera Masking tape Measuring tape Different type of light sources Colour pyramid Notebook
METHODOLOGY Step 1. By using measuring tape measured the distance of 1m from the light cabinet and mark it with masking tape. And repeat the process again but this time for 2m distance from the light cabinet. Step 2. Place the light sources that wanted to analyze, and then stand still at the 1m and 2m mark that been marked to take picture of it. Step 3. From step 2, 1 person stand facing the light box with the light sources that wanted to take picture, and another student are to switch on the light on the light cabinet where the other student turn off all the light on the lab and also lower down the bind around the window so the lab will be dark and the only light sources are from the light itself. Step 4. Hold the camera, and wait about 10 second before took an picture so the camera can adjust itself to the room setting. Take picture of both from 1m and 2m respectively. Step 5. After step 4 done, take the lux meter and make sure the light from the lab still of and place the lux meter top of the colour pyramid for about 510 second before take and the digit to ensure the average reading of the lux meter. Step 6. Repeat the step 2 – step 5 but using different light sources example such fluorescent, bulb, halogen, led and such. Step 7. After step 2 – step 6 data collected done, analyze the result for each light source and from the observation of the light colour rendering. Do compare it one to another.
