Article on CFL vs Incandescent

There are many variables to consider. After reading this, a ban on incandescents makes no sense.

Their server won't load the page right now. But it really doesn't matter. OLED lamps will replace incandescent, CFL, and the current cheesy illumination LED (appear to be white, but are missing major bands of color) bulbs.

With OLED's bright, full-spectrum, super-efficient lighting, the relative merits of interim technologies are moot.

What temperature in K do the OLEDs produce. I've always felt that incandescent bulbs produced a depressing light. 6500K is about right for my eyes.

I didn't read the whole article, but I think a common mistake in comparisons and touted advantages is the assumption that the incandescent lamp that is being replace is used a LOT.

If, as I do, you only use the tungsten lamp briefly and occasionally, many of the benefits of the later lamp types becomes unimportant.

Interesting article, especially regarding Power Factor problems.

The article does confirm repeatedly just how stupid and/or dishonest politicians and bureaucrats are. But we already knew that!

I tried again and got the article to load. Very well researched and well written. It's the best single source of good information I've seen on the subject.

The author does not address how LED lighting scores on the Color Rendering Index. But then, his article is a comparison of CFL's to Incandescent bulbs. What he does write about LED's is factual, so I'll not fault him for that.

LED lighting CAN be manufactured to be full-spectrum white light which provides perfect color rendering. Trouble is, that is still more costly to manufacture. Most common "white" LEDs convert blue light to an (approximate) white light spectrum using photoluminescence. The resulting light looks similar to white but, as with common flourescent lamps, lacks certain bands of color, resulting in poor color rendition.

Organic LED panels promise high output full-spectrum, white light at reasonable manufacturing cost. The first commercially available OLED lights were offered in May of this year. Philips Lighting opened up a webshop upon which OLED lighting samples under the brand name 'Lumiblade' can be ordered online.

The future is bright!

You are being too kind.

Just read the part about using CFL's in sealed enclosures, and how that's a bad thing because the electronics can go above 50 deg. C quickly, and the article says that's when CFL's fail prematurely.

I've got on in a "sealed" ceiling enclousure, and it's been there "pretty long"...maybe a year or so and it's still going strong. I use CFL's in the ceiling fixtures because I've got 11-12' ceilings, and the ladder is five flights down in the basement. Is there anyone else using CFL's like this, and does your experience match what's reported in the article? I'm only into the first year of intermittant use...when it's on it's on for an hour or less. According to the article I'm running that CFL above its specified temperature. What I don't know is how long it's going to last like that...but so far, anyway, it's just fine.
