You can read the whole thing, but I think what writer Andrew Rice decided to close with what sums up the argument pretty well. Why are we changing in the first place?

Later, the committee heard from a panel of experts, including Howard Brandston, a former professor at R.P.I.’s Lighting Research Center. Brandston’s résumé includes everything from theater work to illuminating the Statue of Liberty, but lately he has become the Paul Revere of the movement to save the light bulb, giving speeches to industry conferences and a Tea Party rally in front of the White House. In his testimony, he warned of potential problems with compact fluorescents, which contain trace amounts of mercury. “Some of the most knowledgeable people I know,” Brandston said, “have begun to stockpile a lifetime supply of incandescent lamps.”
A few weeks later, Brandston showed me his own hoard, in the basement of his handsomely lighted farmhouse in upstate New York. “This is the world’s greatest marketing scheme,” he said. “You get the government to ban the competition.” A slight man with an air of gray-bearded grandiloquence, Brandston contends that his root objection to the law, which he calls “immoral,” is connected to his professional appreciation of incandescence, which mimics the natural spectrum. “It’s what we grew up with — it’s sunlight,” Brandston told me earlier on the phone.
Joined by Kevin Simonson, a former student, we went out to Brandston’s garage workshop, where he had set up a spectrometer above a table with three light sockets. Brandston turned on one socket, which contained an incandescent, and a readout appeared on the laptop that was hooked to the spectrometer: a smooth bell curve across the visual spectrum, running from blue on the left to red on the right. Then he switched to a compact fluorescent, and an ugly pattern of spikes appeared. “If you can live with that, O.K.,” Brandston said with a huff. “But what you’ve done is you’ve taken away my choice.”
From my bag I retrieved a Philips L Prize entry, which had been burning agreeably in my office for weeks. Brandston looked at the yellow thing skeptically — he’d told me he considers L.E.D.’s “a fad” — and screwed it into a socket. The bulb gave off a lustrous white light, but the computer readout showed a spectral composition very different from the incandescent’s: a little bit of blue, more green and yellow and a tall peak of red — a combination engineered, according to Lumileds scientists, to the eye’s sensitivities.
“That’s not bad,” Simonson said. But Brandston remained stubbornly unimpressed. “It lacks the vibrancy,” he said, and he began to seek out faults, finding that the bulb took on a sickly green hue when it was dimmed. Anyway, the whole project seemed absurd to him: why create a technological marvel just to reproduce the light we already have? When Brandston turned on the incandescent, he beamed with satisfaction at Edison’s warm and wasteful glow. “Look at that,” he said. “It’s a perfect thing.”

Good question.
