Pros & Cons

Incandescent bulbs:

Advantages:
-Cheap bulb prices
-Most commonly used, so more options

Disadvantages:
-Most energy is wasted by heat
-Expensive running cost
-Short bulb life length
-High wattage

Light-emitting Diodes:

Advantages:
-Very cheap running cost
-Very long bulb life length
-Produces a good light
-Low wattage
-Does not waste energy from heat
-Eco-friendly use of materials

Disadvantages:
-Cannot produce as much light when compared to conventional types
-Initial installation and bulb replacement more expensive
-Not very common, so less options
-Bulb type cannot replace an incandescent bulb

Compact Fluorescents:

Advantages:
-Low wattage
-Fairly low bulb price
-Low running cost
-Compatible with most fixtures
-Long life life

Disadvantages:
-Method of producing light can be harmful
-Harmful greenhouse gasses are used

I drew this picture to represent the heat energy that is wasted of incandescent lights and show the low energy requirements of CFLs and LEDs

Re: Finding lights

I've figured out which CFL's and incandescents to work with; however since LEDs aren't as common It will take me a while to compare the many different brands and models. So for the mean time here are the CFL's and incandescents; I will post an LED when I'm done sorting through the options.

CFL's:

Philips 23W Twister soft white energy saver compact flourescent.
-$11.49 for a 4 pack
-2700K colour temp.
-12000 hour life length
-1600 lumen light output
-23 Watts
-120V

Philips 13W Twister soft white energy saver compact flourescent.
-$7.98 for a 4 pack
-2700K colour temp.
-12000 hour life length
-900 lumen light output
-13 Watts
-120V

Incandescent's:

Sylvania 60W Double Life SoftWhite
-2850K colour temp.
-2000 hour life length
-770 lumen light output
-60 Watts
-120V

Sylvania 100W Double Life SoftWhite
-2850K colour temp.
-1500 hour life length
-1530 lumen light output
-100 Watts
-120V

Finding lights!

I will be looking for some commonly used lights this week so I can hopefully make a decision to which type to base my calculations off. I need to find about five of each CFL, LED, and incandescent so I have a decent variety to select the most fair option. I will post which lights I believe will be the best options so if anyone disagrees or has a better option you can comment.

New Proposal

Lighting Economics

Thesis:

How can energy consumption be reduced by the use of LED (light emitting diodes) and compact fluorescents (CFL's) in lighting design throughout Canadian homes?

Purpose:

Since climate change has been developing to be a major problem of this century, I will be looking into the use of energy efficient and low carbon dioxide and mercury emissions in residential lighting techniques. My objective is to investigate how much energy can be saved using LED lighting or compact fluorescent lighting (CFL) instead of conventional lighting applications and how long it would take to pay off the installation cost difference.

Goals and objectives of the project:

To conduct a cost analysis comparison between an incandescent lighting design, a low voltage LED lighting design, and a compact fluorescent lighting design in a standard house to produce a cost difference and emission reduction report.

Methodology and analytical approach:

I will be comparing the cost benefits of compact fluorescent lighting (CFL) and light emitting diodes (LED) lighting to incandescent lighting. To do this I will determine the best of option of bulb for each compact fluorescent, LED, and incandescent to keep it fair. I will then calculate the lumen output of each type in a standard room and adjust the amount of lights of each kind to guarantee equal systems.

Once the lighting systems are all determined equal, I will conduct a cost analysis for each LED lighting, CFL, and incandescent lighting systems. To do so each type of light will be broke down to three main parts; the light efficiency, installation cost, and replacement cost will be investigated and calculated. With these results I will determine the amount of emissions that can be reduced by using these types.

The final part of my research will be to compare the results and research the benefits and drawbacks of each type of lighting. With a final cost of each system, I will calculate a “pay-off” time of LED and CFL compared to the conventional incandescent type. If the use LED and/or CFL is a great savings (around 5 year pay-off) I will then continue my research to determine how common these types are in recent construction. If the pay-off time is long (around 20-30 years) I will investigate what could be done to improve the use of these high efficiency lights.
