In only about half a month, at the stroke of midnight Jan. 1, 2014, it'll be lights-out for the era of the incandescent light bulb.

Under federal legislation enacted in 2007, it will become illegal to manufacture or import traditional 60-watt and 40-watt incandescent bulbs -- effectively making the traditional light bulb a thing of the past.

At least one of the country's biggest hardware stores is reminding consumers their yellow-hued lighting days are coming to an end.

"Stock up on incandescent light bulbs before they are completely discontinued," the Home Depot Website alerts it visitors. "Get them while you still can."

Home Depot has a six-month stockpile of incandescent bulbs, according to Mark Voykovic, the store's national light bulb merchant.

"Home Depot anticipates running out of their stock of 40W to 60W bulbs six months into 2014," he told FoxNews.com. As such, the home improvement giant is making "a concerted effort" to educate employees and customers about the phase-out before this coming June.

The 2007 dictates manufacturers must make improvements so that 40W bulbs use only 10.5W and 60W bulbs 11W. Althought that doesn't directly ban the remaining two wattage levels of incandescents from the market, it might as well because the long-standing bulb designs need more than the new power allowances to work.

So, the incandescent bulbs will give way to the twisty compact fluorescent (CFL) and newer LED bulbs, which are 80 percent more energy-efficient than traditional bulbs .

Voykovic noted a recent uptick in incandescent bulb purchases over the last several months, "but there's always a bump in light bulb purchases over October and November," he said.

"No, I'm here to buy light bulbs," said Jimmy Rodriguez, 41, a construction contractor from Alhambra, Calif., standing outside his local Home Depot. "Ever since Congress outlawed ordinary light bulbs, I've been stocking up, buying a little here, a little there. They look so much warmer than most of the bulbs on the market today."

Several other Home Depot customers, like Jane Thompson-Huey, an insurance company secretary from South Pasadena, lament the impending ban on incandescent bulbs for the "colder, less welcoming" bluish and stark white hues the CFL and LED bulbs tend to emit.

 "I know it's better for the environment, and the LEDs allow you to save more energy, but the traditional light bulbs were from my youth. They remind me of many of the same feelings I had when I was a girl," Thompson-Huey said.

"Sometimes, change, even when it's for the greater good, is bad."

The law doing away with incandescents was signed by President George W. Bush .

National Electrical Manufacturers Association, the main trade association for bulb producers, asserts that no matter where they fall on the change-over right now, they will eventually welcome the lower energy costs and savings the law was intended to bring about.

"NEMA's members are in the energy efficiency business," NEMA spokeswoman Phallan Davis told FoxNews.com. "Electroindustry products are becoming more and more energy efficient and the systems that often manage their use add to energy and cost savings. NEMA believes that energy efficiency policies, for the residential, commercial, and industrial sectors, should be a central component to any national energy policy."
