A wired house, consumes less electricity?

I would highly doubt it's any form of color blindness. If anything, I think it might be that I'm very sensitive to subtle variations in colors (I'm one of those people who can look at 30 shades of beige and tell you the differences between every one of them). I also don't like incandescent lights on a dimmer that turn everything slightly yellow. I'd rather turn the lights completely off.

I was actually thinking of perhaps missing one extreme or the other, or both, of the normally visible spectrum. For example: if you can't see indigo, and a light source of 'x' luminosity was missing red, then you would see it as dimmer than another source of 'x' luminosity that includes red. You're right that it probably isn't applicable, though. (Come to think of it, I'm not even sure that it makes sense.)

edit: Ooops, there goes my watch beeper. Time to log off, cash out, and go party. Catch you tomorrow.

There have been studies done which show that school children perform much better at just about everything when the classrooms use all natural full spectrum light.

Are there any affordable full spectrum fluorescents on the market??

Wavelength peakiness vs color temperature

The reason fluorescent lighting seems artificial is because blue light [...] isn't natural.

That is not true.

While fluorescents across a broad spectrum of color temperatures can be selected from, those with low CRI ratings tend to be more peaky in their wavelength distributions. One solution to peakiness is to select a fluorescent lamp with a high CRI rating.

Those two pages of that link seem to support ShawnD's claim, not refute it. On the second page, it says, "Natural daylight and any light source approximating a blackbody source (see color temperature) is assigned a color rendering index (CRI) of 100." Then in the table, it again shows that incandescent lights are rated 100, and the highest rated fluorescent light in that list is rated 86 (others are as low as 55). Hardly comparable to natural daylight.

CRI is not a measure of color temperature.

 

[Moonbear]

CRI is not a measure of color temperature.

But the color temperature page had nothing to indicate fluorescent light was the same as natural sunlight either, and instead made the contrast that it is not as continuous a spectrum as natural light. It was saying different sources of light are different in temperature.

CRI vs color temperature

There is no such one single thing as "fluorescent light".

the color temperature page [said fluorescent light is] not as continuous a spectrum as natural light.

It does not say that. It says, "fluorescents [do] not resemble black body radiation."

It was saying different sources of light are different in temperature.

Yes. It has a table indicating that sunlights (contrary to ShawnD's claim, and except for low-azimuth instances) are bluish, that incandescents are orangish, and that fluorescents of varying designs run the gamut (from bluish to orangish: 6300K, 5200K, 5000K, 3400K, and 2950K).

ShawnD said that both daylight and incandescent lights are easy to see by at least partly because because neither are very blue. He was correct about the incandescents not being very blue.

You people argue too much

What? You mean they have the flu?

I thought he said fluorescents made things more blue, not less blue.

That is correct. Fluorescent lamps and incandescent lamps are different things. Typically, fluorescent lamps are more bluish than incandescent lamps, and ShawnD said bluish light is hard to see by.

Fluorescent lamps look like this:

I just went and got a burrito at the local 24hr Mexican drive thru. While I was sitting in line I looked up and saw the long flourescent tubes. they also had a fan above the door and from where I sat in my truck I could see through the spinning fan blades to the lights. outside the fan blades the light looked white, but through the fanblades it was blue, slowly changing to orange then slowly back to blue. first time I've ever seen a spinning fan give a prismatic effect.
also the first time I've ever been told that I owed cinco y cinco. which I thought was $5.05, but turned out was $5.25. I'll have to think about that for a little while.

Just an addon here:
The bulbs used in the lamp I love so much are T3 78mm halogen bulbs. This light doesn't reflect too well. My room is sort of dim, and very relaxing

 

[hitssquad]

The bulbs used in the lamp I love so much are T3 78mm halogen bulbs.

So the color temperature is around 3000°K?

Penguin, you bastard! I knew I should have quoted you before. Now my post doesn't make sense.
