Bringing Choices To Light With A Light Bulb Science Project: Which Bulb Is Best? The Conclusion #GELighting #cbias

Over the last few months we have been switching out our bulbs from the incandescent to energy efficient bulbs. I wrote 2 months ago that we all needed to start doing this because things were about to change! I told you about the legislative changes coming in January. January is now here! I can’t believe it! But that means that changes are now in effect.  What does that mean for you and me?

That was the BIG question!  I wanted to be more informed and I wanted to help you with the new changes as well. I partnered with GE to do an experiment to learn a little more about our new choices.  As a part of my partnership I received coupons for the GE light bulbs for this project. This project idea and all opinions posted about my GE Lighting experience are my own. Here is a recap of the changes in Lighting Legislation.

Our Lighting Experiment

When I told the kids what we were doing they were so excited! My daughter, who is in first grade, really got into it. We had a lot of options and ideas about deciding which ones were the best and what is the difference between them all. We were ready to start our home science experiment.

First things first, go shopping! I recommend shopping with your son/daughter and show them the options. Show them the soon to be old options and the new options. We choose 3 different bulbs and the items needed to build a science project board. It was overwhelming shopping but it was a great learning experience for us all.


The Question:

  • Do all energy efficient bulbs produce the same kind of light?
  • Do all energy efficient bulbs produce the same amount of heat?

Possible Hypotheses from a 3 and 6 year old:

  • They all produce the same amount of light.
  • They do not produce the same amount of light.
  • They all produce a different levels of heat.
  • They do not produce the same level of heat.


  1. Have an adult place each bulb into the each lamp and turn them on.
  2. Observe the light that is produced from each lamp.
  3. Hold a thermometer three inches above each bulb for one minute and record the temperature as well as the length of time the light has been on.
  4. Leave the lights on for an extended period of time. At different times repeat steps 2 and 3. Has the light changed? Has the temperature changed? Record all the information and the time.


It was fun checking back each day to check the look and temperature. Each day we recorded the temperature of all 3. We also would make a note of how they looked. We all agreed we liked the soft look.

Results: What did we discover?


We took the temps of all three over the 2 month period and got an average. The temperature was a great indication of how much heat the bulb let off, how much energy it used and how hot it made the room. There was a very clear winner and loser!

The Winner is GE GE energy-efficient Reveal 60W replacement with an average temp of  91.7!



Each day as we checked the same bulb stood out to us as being the softest. We really liked the glow it gave. It is the look I would like throughout the whole house. I prefer the soft white over the yellowish glow.

Our favorite was the  GE energy-efficient soft white 60W replacement!

The Presentation:

This week we prepared an awesome display board to show off our results.

Changes in your home:

Now that you have seen our Light Bulb Science Experiment results what do you think? Which would you choose? Does the temperature or glow mater to you? Be sure and visit GE on Facebook and Twitter  for all the latest in news, savings and technology.
