Use of Incandescent Lighting
Transcript of Use of Incandescent Lighting Video
NARRATOR: A man holding a light bulb.
BRYAN: Incandescent lighting—and you can think of the regular 60-to-75 watt bulbs—are superb for high contrast, and yet they have minimal glare. If you use incandescent lighting for room lighting, such as up in the ceiling, it has a wonderful advantage of having a warm hue in the room, and it has very minimal glare, as opposed to fluorescent lighting. However, it may not be as even. But particularly, it’s helpful for task lighting, such as writing, reading, cutting and preparing vegetables, and other tasks, like sewing.
NARRATOR: The man and a senior-aged man in a bathroom.
BRYAN: In this bathroom, we have incandescent lighting from the ceiling that gives overall room lighting. We also have some wall incandescent lights that face upwards, to give even brighter illumination.
NARRATOR: The older man flips on a light switch.
BRYAN: Then, for tasks like reading a prescription bottle, or putting on your toothpaste, we have a desk lamp that gives light right where it’s needed.
NARRATOR: The senior man looks at a pill bottle under a desk lamp. Then, he sits at a desk and a woman stands nearby.
BRYAN: This is an incandescent desk lamp, with a very adjustable swing arm that can be positioned at the desired height to provide maximum illumination. It’s bright, yet has very minimal glare. Ida’s showing Ed how to position this for tasks like looking at his Reader’s Digest—that’s in large print—dialing the telephone, and seeing the numbers more easily. When he’s looking at phone numbers in his Lion’s Club Directory, and for looking at statements, and for invoices.
NARRATOR: Ida adjusts the lamp position separately for each type of task.
