The first upgrade that I did on our home was to try and reduce our electrical consumption by replacing the incandescent bulbs with compact fluorescents (CFLs). CFLs use about 75% less energy than a regular incandescent bulb and last about 10 times longer. If every household in the US replaced their 5 most used incandescent bulbs with CFLs, we would save approximately $8 billion each year in energy expenses. This is the equivalent to the emissions of nearly 10 million cars.
This was all the information that I needed to get interested. On my first outing to the hardware store, I returned with a four-pack of CFLs. I thought that I would test them out and see if we could get by without the warm, yellow light. After replacing the four 100-watt incandescent floodlights with 18-watt CFLs, we began to test our comfort to the new blue light. It instantly turned our kitchen into a cold place and I noticed that we kept turning on other nearby incandescants to compensate.
I went back a week or so later to try and read the packaging more carefully to find a CFL that could better match the yellow tone we were used to. I remembered seeing several different varieties and some that were actually covered in a yellow diffuser. I knew there had to be something that could work so I ended up coming home with three different bulbs. All three of these new bulbs had a near perfect yellow hue. One of them seemed to have trouble getting started and would take a short while to get up to full power. I was a bit confused why it did this so I looked a little more closely at the packaging and began to notice a little warning on the back about Mercury content.
This was not the cause of the delay but it did stop me from buying any more CFL bulbs. I didn’t even want to think about how many of these are going to end up leaking in the landfill despite recycling efforts. Will the Mercury content of these new light bulbs end up doing more harm than the emissions caused from powering incandescent bulbs? Michael Richard over at TreeHugger does a reality check on this mercury risk by comparing it to the amount of mercury that is released from burning coal in order to power incandescant bulbs. This is a great bit of information, validating the environmental savings over incandescents. However, I’m still going to look into LED lighting as my next step.
