LEDs are over ten times more efficient and the directionality of the light can be solved in a number of ways.

What are you smoking?

Incandescent from my closet: 100 watts, 1690 Lumens or 16.9 lumens/watt.

CFL: 27 watts, 1750 lumens or 64.8 lumens/watt.

Let's find a few LED lights...

LED spotlight: 8 watts, 120 lumens, 15 lumens/watt.

Bulb toward end of page: 10 watts, 200 lumens, 20 lumens/watt.

How about this $70 bulb? Surely that one must be bright! Nope: 10 watts, 340 lumens, 34 lumens/watt. Better, though -- half as efficient as the CFL, but still too dim for good room lighting.

LEDs are pretty cool for certain uses, but they SUCK for general purpose lighting.

I purchased my LED lamps from http://www.besthomeledlighting.com/ they gave me a quantity discount. There are many others out there as well. I just think of it as a 0% interest buy down on my electricity for the next 2 years and after that its pure ROI :)

This 20 year bulb is cool, but expensive and less efficient that a CFLs. http://www.besthomeledlighting.com/product/OBS-80- 260-E27-96-WC On the other hand, my outdoor lights are solar LEDs.

Oh, I don't know...

Here's a 4 watt light bulb for example.

And a host of LED alternatives:

And here's a spreadsheet to compare all three:

Anything else?

I'm pretty sure most homeowners know about CFL's, and a lot of them probably have one or two already. (So where's that city of 1.5 million that's now being powered by all that saved electricity?) My house came with a couple that the previous owner had put in about three years ago.

The problem with these is the same as with any other flourescent light. Namely, they make ugly light and they hurt your eyes. Until that changes (read: never), don't expect people to be replacing their incandescents. It's not just a question of economics; light quality is just as much a health issue as air or water quality. Flourescents have been proven to cause a variety of sight-related issues, including eye strain and headaches.

But the good news is LED light bulbs are getting better and more common. Here's an example of what's available. No, I don't work for an LED manufacturer or seller, and no, I don't think LED bulbs are quite there yet. But they promise to provide a dramatic decrease in energy costs (about 1/10 the energy of even a CFL) and they can provide pure white, steady light (which CFL's, by their nature, cannot do). They are the future, and they're now starting to be carried by big box stores like Lowes and Home Depot.

CFL's have been around for a long time and their lack of success isn't because of cost or because people don't know about them. It's because people don't want them. That's a different thing. News articles can do a lot to raise awareness, but they can't do much when that awareness already exists and people have made up their minds.
