relatively new house to me, and it turns out its the only room in the house that doesn't have a smoke detector. the rest of the house has wired smoke detectors with battery backup
Guess what i'm doing TODAY!

I've not decided if i am going to tear it down, or contact the manufacturer on this.. but it is not like i care about getting a replacement under ther "5 year warranty" not like i want another one of these.

I would still raise a fuss with the manufacturer, send them pictures etc.  The more people do this the more they might realize that it's actually important to put some safety in their stuff so that it does not burn houses down.

I'm begun to replace all of the incandescent flood lights in all of my house's ceiling fixtures (about 30 of them) with LED bulbs and am concerned about the failure modes of these bulbs. When incandescent bulbs fail, they just pop their filament and that's it--no melting of the bulb housing. LEDs tend to fail more spectacularly and I'm not sure that I trust them not to start a fire.  :palm:

The bulb was rated for a recessed fixture also rated indoor outdoor and dimable.  I actually had it in a ceiling fan, in one of the fluted glass fixtures to shine light in the area the kids play. (pictures attached below)

Doing a little research, seems these were sold circa 2011, so that is about right, its when i moved into the house so i might be past the 5 year warranty ... figures.

I have another in the house in a recessed spotlight...which i just pulled it out and its in great shape. however the light is not used often.. i'll do a disassembly of it and leave the burnt one alone.

these were $30 a bulb when they first came out. (found a thread here on them) http://www.candlepowerforums.com/vb/showthread.php?313789-Trying-out-the-new-Home-Depot-EcoSmart-LED-BR30-bulb
Good pics of the packaging there also.
 
the base is ceramic plastic, so what you see burnt and bubbling actually burst / burned though the ceramic plastic insulator at the base.
the white fins you see are metal heat sink fins, not plastic.

this was back when you paid a hefty premium for an led light, even the home depot brand.
chances are it is right at the 5 year mark - they advertised these to last 23 years.
