26
Q

What does Arbitrary mean?

A

based on random choice or personal whim, rather than any reason or system.

27
Q

Lamps is commonly used in residential setting. True or false?

A

True

28
Q

What is halogen?

A

Is a subcategory of incandescent lighting. It is more accurately called Tungsten-Halogen or Quartz Halogen.

29
Q

Halogens have a higher rate of efficacy. True or false

A

True

30
Q

What is efficacy.

A

This is the criterion that is used to evaluate the amount of brightness a lamp source provides in comparison with the energy used.

31
Q

What is a Reflector lamp

A

Is the used for several types of incandescent lighting sources that direct how the light is reflected, causing a manipulation of its shape and focus.

32
Q

What is a reflector

A

It is a surface of mirrored glass or polished metal shape to project the beam from a light source in a particular direction.

33
Q

What is s beam spread

A

Distribution of light

34
Q

What is the United States and Canada voltage standards

A

120 V

35
Q

When was the fluorescent light first introduced?

A

In 1938 worlds fair in New York.

36
Q

What is Neon lighting

A

It is colored light that is produced as a result of different gasses, or vapors.

37
Q

What Is a High Intensity Discharge (HID) lamp

A

Are extremely efficient and are used for large scale commercial applications.

38
Q

How many categories does HID have? And what r they?

A

It has 3; Mercury vapor, high-pressure sodium, and metal halide.

39
Q

When r HIDS most used

A

When lighting must remain for a long period and where maintenance would be inconvenient.

40
Q

What is accommodation

A

The ability of the eye to focus at different distances, under normal conditions

41
Q

What is adaptation

A

The normal process of the eyes adjusting to change in the brightness of light.

42
Q

What is glare

A

Brightness that is more than the eye can naturally adapt to.

43
Q

What is veiling reflection.

A

light bouncing off a surface

44
Q

What is full spectrum light

A

White light

45
Q

What is metamerism

A

Describes the phenomenon in which color under different lighting situations do not appear the same.

46
Q

What is color rendering index

A

An international system for comparison to rank light sources with respect to color rendering.

47
Q

What is throw distance

A

Is used to describe how far and at what intensity the illumination will go.

48
Q

What are the 2 ways to categorize illumination

A

Diffuse lighting and Directional lighting

49
Q

What is diffuse lighting

A

Fluorescent, not illuminate any specific object but provides an overall uniform illumination to a space.

50
Q

What is directorial lighting

A

Light that travels in a single direction, illuminating specific objects and surfaces

51
Q

What is a spot

A

A beam spread angle of less than 25 degrees

Q

What is a flood light.

A

Beam spread more then 25 degree

53
Q

What is Lighting reflectance value LRV

A

It is the measure of a scale form 0 to 100%. At 0% no light is reflected, at 100% all lights is reflected

54
Q

What is wall washing

A

It is a technique used to provide a smooth distribution, or wash, of light over vertical surfaces or planes. Usually an entire wall

55
Q

What is scalloping

A

It is a particular type of grazing that calculates spacing in such a way as to
Creat overlapping pool of light shape like a scallop.

56
Q
