OK, now to get in on the CFL controversy.
1. How many of you 50+ folks out there played with liquid mercury as a kid? Wasn't it fun rolling the little spheres around the table? Putting it on a penny and discoloring it?
2. What about that mercury amalgam in your tooth fillings?
3. When in pharmacy school working at a dermatology clinic, I make countless gallons of ammoniated mercury suspension for seborrhea. No laminar air flow hood. I'm talking tens of pounds of that raw ingredient over 3 years.
4. As a health professional, I do recommend limiting your exposure to mercury to as little as possible. It really is toxic, but some very limited exposure should not cause harm. Don't swallow it! Try not to breath it. (I'm almost 60, but some of my "friends" think I have brain damage!
) Just be careful cleaning up broken CFL and standard florescent bulbs when they break.
5. Those damn CFL bulbs do NOT last longer than the incandescent. I replace those CFL bulbs on my outside lights (which I leave on all night for security) just as fast as I replaced the heavy duty incandescent bulbs in the same fixtures.
6. Please get the price down on LED's. They show great promise for saving energy and lasting longer.
(And I agree Cary, I think that story would have been about phosphorous.)

I agree with you, the LEDs are useless - I have a couple of LED lamps and it's like being in a cave. It really irks me that we can no longer buy incandescent bulbs in AZ

JP, What is wrong with you? Those lights were easily accessible to Dino. After all of Chongo's shenanigans and you invite more?
Dino is a lot easier to contend with than Chongo ever was. Dino has a healthy respect for physics that Chongo never did or at least an understanding of where there is potential for harm.
As for the lights, not a fan of them, stainless steel hanging over the dining room table. If it were my house they would be gone in a flash. The good thing is they are really hot so there won't be any extended play with them and no fascination when they are turned off.

There are some emerging technologies out there on the LED front that will change some things. First off, they continue to get incrementally brighter, and the price continues to fall.
There is one company that has found a way to more densely pack LEDs by use of a special glue and more remote heat sync. They also can mount a lot of different lenses in front of a cluster of LEDs. Doesn't sound like that big of a deal, but it doesn't just allow packing more light in a small area, but light that has a better spectral response because they don't need to pack things with just one color type of LED.
My biggest complaint with all the new lighting technology is that we aren't to a point where the mainstream products take into consideration color rendition. That used to be the case with fluorescents when a grocery store didn't have a light source that made both lettuce look green and tomatoes look red. Eventually it was resolved, but long after the technology was out there.
Me, like many others still have a fondness over incandescent lamps, despite having CFLs in all our lamps and lighting. It's difficult for most to express what they really like about them, but they have a high color rendering index number, meaning the color you are seeing is accurately illuminated. LEDs and CFLs have a very low CRI number, which usually falls in the 60s or 70s. Incandescent lamps have avery high CRI generally in the 90s and as high as 100.
So for me it's not so much how bright CFLs or LEDs are, it's all about the color representation of what I am looking at.
Oh and a little fun fact, women see color much better than men.

Are we talking about cats or just in general?

LOL! No idea about cats, but human women see color better than men.

Cats are to some degree color blind. They do not see red. It appears gray to them. They have no red cones in their eyes.
