The cost of electricity dominates bulb costs. Here's some quick approximate math.
40W incandescent, $1 cost, 1,000 hours life.
10W LED, $5 cost, 10,000 hours life.
Electricity $0.12 per kWh, my cost is about USA average.
In 10,000 hours of use, incandescent cost is $10 for bulbs, $48 for electricity. Total $58.
In 10,000 hours of use, LED cost is $5 for bulb, $12 for electricity, Total $17.
$17 is much less than $58.
In reality a 40W equivalent LED would use closer to 8W than 10W, and would last longer than 10,000 hours, and costs less than $5, so the comparison result would be skewed even more toward LED.
Now what happens if you live in Germany. Electricity is €0.31. Which is 3x what I'm paying. So now the electricity comparison is €124 for incandescent, €31 for LED.
- grawprog 6y agoYa know, i mentioned above, I don't like the light LED's produce. I notice the difference and for me the difference in price in the end is negligible I really don't understand this incessant need to convince people they should switch to different lightbulbs, when my choice in lightbulbs in no way impacts anyone else. I live in a place with 100% renewable power. As far as i'm concerned, the simplicity and lack of chemicals in the bulbs I choose, outweighs the potential energy savings as far as that goes. My choices come down to what I prefer and what I feel my impacts are based on those choices. I've thought it out and this is what I choose and I shall keep on doing so until I no longer can and the lobbying has forced incandescents entirely off the market.
