Compact Flourescent test results

Back in January I posted an article about CFL lights. I decided to run a test, replacing 6 of 7 light bulbs with cfls.

I’m happy to announce, the results are in. All 6 of the CFLs I installed are still burning brightly, but last week the lone incandescent burnt out. Obviously, this isn’t a perfect test, maybe I will run it again. I still have some incandescents, I think I will replace the burnt out bulb today with a new one and see if it lasts longer than the cfls.

The interesting thing would be to see if I can establish how long the bulbs last, and compare the costs with them. This CFL Savings Calculator, with it’s default settings, shows a savings of $0.44/month or $8.86/year for each CFL bulb. It would be interesting to see if my data supports that. If their numbers are accurate, and I have about 20 bulbs in my home, the total savings would be around $175/year. That’s not a huge amount of money, but worth doing.
