The purpose of this research was to study the satisfaction and the intensity of the light reflected from the surface of the ตัวสะ lamp glass and side. At the height 381 mm in light 5 watts and 12 Watts by students at 4.Faculty of public health and environment during the academic year. 1 2557 huachiew chalermprakiet University divided according to high 3 groups as follows. Percentile at 5 (P5) were 10 people percentile at 50 (P50) were 9 people.95 (P95), a number of people, including the end of 6 25 people
.The effects of research and found that 1) using a reflective surface glass bulb size and 12 watts to levels of intensity, light at the 1319 Deluxe, which had the most light intensity and followed by reflective surface model in กับหลอดไฟ size 12 watts, with the intensity of the light, that 1034 Luxe reflective surface glass bulb size and 5 watt level of illumination at the 958.12 Deluxe and a reflective surface. Lamp size 5 watts, with the intensity of the light at the 745.52 Deluxe, respectively 2) efficiency of the bulb by hundreds of needle 5 watt bulb in the reflective surface mirror have hundred needle in 6.19 seconds, which soon followed by 5 watt bulb in a reflective surface in time the hundreds and fellow at 6.44 seconds. 12 watt bulb in a reflective surface in time hundreds of needle in 7.67 seconds and 12 watt bulb in the reflective surface mirror have hundred needle in 8.54 second side respectively 3) 5 watt bulb surface reflect the side are the most satisfied with the experiment 12 people, followed by 5 watt bulb is a reflective surface mirror the 9 people. And 12 bulbs.Following the sequence 4
