You can find a good deal on light bulbs at Home Depot and Wal-Mart. Sometimes, customers bring that to our attention.
How do these stores sell at such low prices? Are they selling the same light bulbs as us? They are targeting a more residential customer, so are they selling residential grade lighting products?
Is there something different about a residential lamp when compared with a commercial one?
Usually, no –– there's no difference or distinction, at least according to one of our top manufacturers. Though the products are packaged differently, their guts are almost always the same.
