One of James Clar's art works 'Waveform'.

1) What is the actual difference between light of different colours?

The difference between light of different colours is frequency of EM waves (wave lengths) which determines the amount of energy it contains. Different colours of light have different frequencies and amounts of energy.

2) Define the following lighting terms: (ambient light, direct light diffuser, luminosity, energy efficiency, watts)?

ambient light- The light surrounding an environment or subject.

direct light diffuser- Light that strikes a smooth surface, reflecting back in the same concentration, making it a soft light with neither the intensity nor the glare of direct light.

luminosity- The quality of emitting or reflecting light.

energy efficiency- An appliance or tool that reduces the amount of energy necessary to operate machinery .

watts- A kind of unit of measurement to express electrical power or light.

3) Comment on global warming:

Global Warming is the gradual increase in the temperature of the earth's atmosphere. It was agreed that human activity is very likely the cause for the rapid increase in global average temperatures over the past several decades. We dig up oil and coal and burn it to produce energy, but while doing that, we release carbon into the air which is causing a lot of the global warming. One way to reduce the carbon being released into the air is using energy efficiently and correctly. Reducing the amount of energy you use around the house will reduce the amount of coal that needs to burn to support the amount of power you want.

4) How can the modern home become more energy efficient with regard to lighting?

Instead of using lights like: Fluorescent lights, Halogens or CFL's; use LED lights.

5) Research a modern-day lighting designer and comment on their contribution to the design world:

James Clar is a modern-day lighting designer. He creates a fusion of technology, popular culture and visual information into art. Clar trys to often control and manipulate light. His art work contributes to the design world by showing nationalism, globalism and popular culture in the age of mass information. Also, while exposing the difference between Western media and Middle Eastern media.
