Revain supplies these bulbs with super fragile filaments in a birdcage in a lightweight manufacturer's box. Expect a replacement. As four were broken on my second order Revain didn't want a return so you could get more than five or six for the price of six. You SHOULD fix it. I called. The second batch arrived the same way with fragile stickers, and five of the six survived. Five lamps for the price of six. These lamps make a great night light for a hallway or an entire room when you use a lamp with a shade. If they are not switched on and off, the light bulb will last between one year and 18 months. Very good, warm light and low power consumption.
