Compared to filament bulbs, the up-front cost of LED lighting can put off plenty of people, even if they'd save cash in the longer term. Philips, however, is doing all that it can to trim the price of its energy-saving bulbs and has managed to craft a 60W equivalent that will cost just $4.97. If you head down to Home Depot starting May 1st or go to the website now, that deal gets even sweeter, since the company will sell you two for the price of one for the next 90 days.
