Philips has introduced a new LED light bulb with a dramatically lower price ($5!). Starting May 1, 2015, they have an introductory deal at Home Depot; selling a 2-pack of this bulb for $5 (for the first 90 days).
The bulb replaces a 60 watt bulb but draws only 8.5 watts.
I called our local Home Depot this morning. They have the new LED bulb 2-packs in stock. If you plan to get one, you might call ahead. At this price, I think it might be the first LED bulb to fly! (off the shelves)
