Awhile ago I mentioned that I was starting an experiment on different types of light bulbs. I think that there are three commercially available bulbs on the market.
- Incandescent
- CFL
- LED
I have purchased a bulb of each kind and am conducting an experiment with each of the three. As part of the experiment, I need to account for:
- Quality of light
- Cost of bulb
- Heat of bulb
- Cost of electricity
- Cost of replacement
I just finished my evaluation of the CFL and I must admit, it stands the test of the test.
I find the light to be nearly equal to the light given off by the incandescent. Which to me, in certain conditions, is a deal breaker. Further, the heat given off by the CFL is manageable. While I am unable to unscrew a traditional light bulb while burning, I was able to unscrew a CFL while burning.
So, the financials:
Bulb | Cost per Bulb | Cost per KWH | Cost per hour | Lifespan | 50,000 Hour Cost |
Incandescent | $1.00 | $0.1701 | $0.0070 | 2,000 | $375.00 |
CFL | $1.00 | $0.1701 | $0.0017 | 10,000 | $88.00 |
Not even close. Over the course of 50,000 hours the savings is about 400% over the incandescent bulb., And if you demonstrate the savings in terms of 10,000 hours:
Bulb | Cost per Bulb | Cost per KWH | Cost per hour | Lifespan | 50,000 Hour Cost | 10,000 Hour Cost |
Incandescent | $1.00 | $0.1701 | $0.0070 | 2,000 | $375.00 | $75.00 |
CFL | $1.00 | $0.1701 | $0.0017 | 10,000 | $88.00 | $17.60 |
Again, not even close. However, the difference in 10,000 hours vs, 50,000 hours is that 10,000 hours is very close to a year. Just be switching to a CFL bulb you can save about 60 bucks a year.
Per lamp.
Wow!
The light is a little bit more raw, but, if you are like me, you will have a shade over the bulb. And that shade blunts the glare of the CFL to the point that you can’t tell.
At this point, the CFL wins hands down!
Very interesting, thanks for sharing these results

Yeah, fascinating. Right now, the CFL has come a long way in providing proper light.
