2. Task Lighting

3. Accent Lighting

The four pillars of lighting.

1. Safety

2. Security

3. Stress and mental well-being.

4. Money and economics.

The four pillars are achieved trough? (5)

1. Brightness

2. Color Temperature

3. Color Accuracy

4. Direction

5. Efficiency

Brightness

Refers to how strong, light or dim a lighting is.

Color Temperature

Dictates the color appearance of the light being emitted.

Color Accuracy

Dictates how real or accurate the color of an object under the lighting.

Light output

The total amount of light emitted by the source.

Lumens (lm)

The unit of brightness or light output.

Integrating Sphere

Used for measuring the brightness of a light.

Light Intensity

Refers to the amount of light on the surface of an object.

Lux (lx)

The unit used to measure light intensity.

Luxmeter

Used to measure the lux on an area or object.

Measures the color appearance of the light.

Correlated Color Temperature (CCT)

Kelvin (K)

The unit of Correlated Color Temperature (CCT)

Color Rendering Index (CRI)

Shows how accurate the color of an object is under the lighting.

What is the CRI range of our BRILUMD products.

70-80 CRI

Direction or Beam Angle

Refers to the angle of light coming from the fixture, or how light spills out from the source.

Unified Glare Rating (UGR)

Is the measure of discomfort caused by glare.

Luminous Efficacy (Efficiency)

Refers to how effectively a light fixture uses energy.

Lumens per Watts (lm/w)

The unit of luminous efficacy.

Wattage

Refers to how much energy is required to run the light source.

The wattage of the light to be quoted is how many times the height distance?

Ten times the height distance. Watts = 10 x Height

Questions we must ask prospects when providing lighting solution. (5)

1. Application

2. Location

3. Purpose

4. Existing product being used.

5. Type of lighting to be used.
