I bought these bulbs in the 9, 7 and 5" sizes to go on a string on my house. I was hoping for a similar warm glow to the incandescent icicle light strings I've used in the past with many small bulbs, and these bulbs do have exactly that quality. Next to a hardware store LED light string we had bought, these do look like they're incandescent. They're nicely formed, and give a nice glow. They are plastic, so I'm interested to see how they'll weather, but at least they won't break like the glass bulbs. They come packaged in a nice cardboard box of 25 with dividers in between the bulbs, so good for storing them, too.
