The heat can only move so far when the heat sink is surrounded by plastic with no vent holes.

Actually the cup that the board is sitting on is some kind of heat dissipater. I drilled through to make a vent and saw that there was an aluminum lamination.
The board is likely secured to the base with a thermally conductive adhesive. The base is the heatsink. The LED bulb will cool better in an open lamp vs a closed fixture.

I noticed that on mine too. And I know plastic is not a good insulator, but it is a better insulator than bare aluminum. One LED in the bathroom just started flickering as the others did, so it is not long for this world :headbash:
