From the light bulb package and an internet website, I have the supplier as:

Foodhold U.S.A., LLC
8301 Professional Place
Landover, MD 20785-2237

I have composed letter to them about this matter and now let's see what their response will be.

In the first case it looks like a standard A19 incandescent bulb. In the second case it looks like an A19 halogen bulb. Most likely the "envelope" (actually just a decorative cover) wasn't glass but a polycarbonate or other type of plastic and it melted from the heat of the halogen bulb (the glass bit left behind) or one of its neighbours.

Regardless, both of these bulb types are obsolete and shouldn't be used anymore. A19 LED bulbs are now very cheap (you can get them for less than 0.50 per bulb) and have pretty much replaced incandescent, halogen and CFL bulbs. Using up your old bulbs is false economy as it doesn't take long for the electricity wasted to exceed the value of the bulb.

In terms of specialty bulbs, LEDs are still more expensive, but rapidly coming down in price. Because LEDs are so easy to make in volume, it won't be long before they are the cheapest type of bulb.

The only place you will still want to use incandescent bulbs for the foreseeable future is inside heating appliances (stoves, dryers, etc) as heat is the enemy of LEDs and the waste heat isn't really wasted, but those typically use an A15 Appliance bulb.
