Cool! I wish they had done the math to compute cost per hour. So I did it; they're all roughly comparable, with LED bulbs (as shown) being the most expensive, and halogen after that.

But their prices for LED bulbs are outdated; I've been buying them at Home Depot for about $5 each. At that price, they're about half the cost of incandescent bulbs, and comparable to CFLs as shown.

Of course, I don't buy the lifetime shown (and claimed by the manufacturers) for CFLs, either. I used those for quite a while, and was constantly replacing them. I took to marking the date on the base when I installed, so I could see exactly how bad it was when I replaced them... and typically, it was about a year or two. Pure marketing bunk there. CFLs were a brief misstep in the technology chain, and I'm happy to see them go!

LED bulbs, on the other hand, have not failed me even once so far. It's definitely the future of lighting, unless we come up with something even better!
