Are you looking to test your knowledge about set lighting and color temperature? If you said yes, you are in luck as the quiz below is perfect for helping you test out what you already know about lighting. How about you give it a try and get to see what new things you might learn. All the best as you tackle it!

### The Formula to calculate the wattage of light is...

• A.

Watts = Volts x Amps

• B.

Volts = Watts x Amps

• C.

Watts = Volts / Amps

• D.

Watts = Amps / Volts

A. Watts = Volts x Amps
Explanation
The correct answer is Watts = Volts x Amps. This formula is used to calculate the wattage of a light. Wattage is a measure of the power consumed by an electrical device, and it is calculated by multiplying the voltage (in volts) by the current (in amps). This formula follows the basic principle of power calculation, which states that power is equal to the product of voltage and current.

### The amount of light falling on a surface is measured in ...

• A.

Foot lamberts

• B.

Lumens per watt

• C.

Foot candles

• D.

Micro reciprocal degrees

A. Foot lamberts
Explanation
The amount of light falling on a surface is measured in foot lamberts. Foot lamberts is a unit of luminance that represents the amount of light emitted or reflected from a surface. It is commonly used in the field of lighting design and photography to determine the brightness of a surface. Lumens per watt is a measure of luminous efficacy, foot candles is a measure of illuminance, and micro reciprocal degrees is a measure of luminance gradient.

### An HMI has what color temperature in Kelvins?

• A.

5500K

• B.

4300K

• C.

3200K

• D.

5000K

A. 5500K
Explanation
An HMI (Hydrargyrum medium-arc iodide) has a color temperature of 5500K. Color temperature is a measurement of the color appearance of light, and a higher color temperature indicates a bluer light. HMI lights are often used in photography and film production because they closely resemble daylight, making them ideal for outdoor shoots or simulating natural lighting conditions. The color temperature of 5500K ensures that the light emitted by the HMI closely matches the color temperature of daylight.

### A Tungsten has what color temperature in Kelvins?

• A.

5500K

• B.

4300K

• C.

3200K

• D.

5000K

C. 3200K
Explanation
Tungsten has a color temperature of 3200K. Color temperature is a measurement of the color appearance of light emitted by a light source. It is measured in Kelvins (K), with lower values indicating warmer, more yellowish light, and higher values indicating cooler, bluish light. Tungsten lighting is commonly used in photography and videography because it produces a warm, yellowish light similar to traditional incandescent bulbs. Therefore, the correct answer is 3200K.

### An standard K-mart type of Fluorescent has what color temperature in Kelvins?

• A.

5500K

• B.

4300K

• C.

3200K

• D.

5000K

B. 4300K
Explanation
The correct answer is 4300K because the question asks for the color temperature of a standard K-mart type of Fluorescent. Color temperature is a measure of the color appearance of light, and a standard K-mart type of Fluorescent typically has a color temperature of around 4300K.

### The key light is...

• A.

Usually the first light to be established

• B.

More powerful in intensity than the fill light

• C.

Is placed on the opposite side of the camera-subject axis from the actor's fill light

• D.

All of the answers are correct

D. All of the answers are correct
Explanation
The key light is usually the first light to be established, as it is the main source of illumination for the subject. It is also more powerful in intensity than the fill light, which helps to create contrast and depth in the scene. Additionally, the key light is typically placed on the opposite side of the camera-subject axis from the actor's fill light, further enhancing the three-dimensional look. Therefore, all of the answers are correct as they describe different aspects of the key light's characteristics and placement.

Rate this question:

• 7.

### The fill light is...

• A.

Usually placed near the camera-subject axis and on the same side of as the key light

• B.

Usually placed near the camera-subject axis and placed on the opposite side of it from the key light.

• C.

Usually placed behind the subject directing opposite of the camera.

• D.

Usually placed below the subject to give it a contrasting angle.

B. Usually placed near the camera-subject axis and placed on the opposite side of it from the key light.
Explanation
The fill light is usually placed near the camera-subject axis and on the opposite side of it from the key light. This placement helps to fill in the shadows created by the key light and provide a more balanced and even lighting on the subject. By positioning the fill light on the opposite side of the key light, it helps to reduce the contrast between light and shadow, resulting in a more natural and pleasing look.

### Practicals are...

• A.

Lights we see on camera.

• B.

Used opposite of the fill light.

• C.

It is used to separate the subject form the background.

• D.

It is used to make moonlight.

A. Lights we see on camera.
Explanation
The term "practicals" refers to the lights that are visible within the frame of a camera. These lights are intentionally placed and used to create a realistic and believable lighting scenario within a scene. They are different from other types of lights used in filmmaking, such as fill lights or moonlights, as practicals specifically refer to lights that are visible on camera.

### The real amps for a 10K tungsten light are...

• A.

100

• B.

83.3

• C.

8.3

• D.

90

B. 83.3
Explanation
The correct answer is 83.3 because tungsten lights have a power factor of 0.8, meaning that their actual power output is 80% of their apparent power. Therefore, to calculate the real amps, we divide the apparent power (10,000 watts) by the voltage (120 volts) and the power factor (0.8), resulting in 83.3 amps.

### The type of power distribution system popular in old Hollywood ran at a constant voltage and is still popular around water because it is safer.  It will usually throw you instead of grabbing ahold of you.  It is called...

• A.

Alternating current system

• B.

Direct current system

• C.

Vacillating current system

• D.

Overprotection current system

B. Direct current system
Explanation
The correct answer is direct current system. This type of power distribution system, which was popular in old Hollywood, operates at a constant voltage. It is still commonly used around water because it is considered safer. Unlike alternating current systems, which can grab ahold of a person and cause harm, a direct current system will usually throw a person away from the source of electricity, minimizing the risk of injury.
