How would a $10.00 compact fluorescent light bulb (15 W) be an overall money saver compared to an incandescent light bulb (60 W) that costs $0.50?

Answer 1

This is my personal opinion but I don't think they are. My experience is that the new fluorescent bulbs don't live up to the hype on the box. Supposedly those incandescent bulbs burn out faster and it takes several to last as long as the newer fluorescent bulbs. In addition, that 15 W bulb uses only about 1/4 the energy of a 60W bulb so it saves on the electric bill (that part is true). But the problem comes in the hype of how long those fluorescent bulbs will last. My experience is that those bulbs (and they are VERY expensive) will not last the six-seven years as advertised. Some of mine have lasted less than a year and none have lasted more than two years. Frankly, I don't think that's worth the added cost (3-4x the cost of the incandescent bulbs). One prominent manufacturer advertised that if the new lamp doesn't last at least xxxx years, just return it. When I tried to follow up, I paid the postage to return the old bulb, I paid the postage for the new bulb,
AND I had to have the original receipt showing when I had purchased the bulb. It was cheaper to buy a new bulb and not fuss with the return. I know this is not the answer you and your prof are looking for but it's my opinion and my answer to the question. Other tutors may differ. Such is life, I suppose.

Answer 2

Another thought. Incandescent bulbs don't pollute the environment with mercury. Most fluorescent bulbs(I don't know if all do or not) have mercury in them.
