Designing the Color in Fluorescent Lighting

Our project is all about the colors inside fluorescent lights. A mixture of gases causes the coloring in lights, so we figured out which gas mixtures made which colors.

How Did We Do This?

We took a spectrometer and pointed it at the red areas of our neon sign and then the white areas of our neon sign and it pulled up the wavelengths on our computer. After we saved the results, we compared them to a spectrum of different gases to figure out which gases make which colors. The red light is made up of neon, argon, and mercury and the white light is made up of helium.

Interview with MidAmerican Energy

We also interviewed MidAmerican Energy and asked them questions to help us get a better understanding about fluorescent lighting, how it's better for the environment, the differences between energy efficient and incandescent bulbs, etc.


Interview:


  1. What are the most energy efficient light bulbs?

    1. LED (Light Emitting Diode)

    2. CFL (Compact Fluorescent Lights)


  1. Why are they more energy efficient?

    1. They require less wattage than incandescent bulbs and CFL bulbs


  1. What are the differences between incandescent and energy saving lightbulbs?

    1. Energy saving lightbulbs generate light by sending an electrical discharge through ionized gas

    2. Incandescent lightbulbs generate light by heating the filament in the bulb


4. How much money on average can energy efficient bulbs save you?

  1. Incandescent- $50.25 (monthly cost)

  2. CFL- $11.73 (monthly cost)

  3. LED- $7.97 (monthly cost)

    1. CFL saves an average of $38.52 monthly

    2. LED saves an average of $42.28 monthly

  4. Energy efficient bulbs also last longer, therefore saving you money


5. How much light do energy efficient bulbs emit compared to incandescent bulbs?

  1. Energy efficient bulbs emit approximately 5x the amount of light than incandescents
