So today I was at the grocery store and remembered I had to pick up some light bulbs… I’ve been staring at these CFL (Compact Florescent Light) bulbs for months now wondering if I should be buying them.
I’ve heard they save money, but I’m not the type to believe labels, I’d rather do the research myself. I bought 4 60watt 1,000 hour bulbs for $0.88 CAD ($0.22/bulb), and 6 13watt CFL 10,000 hour (which equals 60watt incandescent) for $13.99 CAD ($2.33/bulb). At this price ratio, you don’t save buying the CFL bulbs – based on just bulb price. Mind you the regular bulbs were on sale 50% off and the CFL bulbs were full price.
The longevity of the CFL bulbs is 10,000 hours is approx 4.57 years of usage (at 6 hours a day), so if you know your going to be in the same house for a while just the fact of saving you from replacing bulbs it’s worth it.
So what about electricity costs? Going by the same math before (and a electricity price of $0.06CAD/kWh) we have:
Regular bulb:
1 60watt light bulb – 1 years (6 hours a day) = 131.4 kWh * ($0.06CAD) = $7.88
CFL Bulb:
1 13 watt light bulb (equal to a regular 60 watt) 1 year (6 hours a day) = 28.47kWh * ($0.06CAD) = $1.71
So per year with 1 bulb you’d be saving $6.17 CAD. Multiply by 10 bulbs and your saving over $60/year.
So now that I’ve done the math, I think I’ll have to buy some more.
Now, comparing the look (which one do you think is the CFL and which is the incandescent?):
Really when I replaced them I couldn’t tell the difference… I’m not sure if this is due to the light fixture or not. The one on the left is the incandescent bulb and the one on the right is the CFL bulb. Both light bulbs are called “soft white”.
The down side to using these bulbs:
So in conclusion, I’ll definitely be using more of these bulbs in the future. Whether you save $288 CAD dollars with 6 bulbs I’m not convinced about that, but I believe you can save $200 CAD with 6 bulbs. Anywhere I can hide the look of the bulb, I’ll be using them.
Have/Will you made the switch, and have you noticed the difference on your bills?
