[title] Examine Thermal Pad
[* black] If you compare the under-side of the PCB with the bulb's case, you'll see if the thermal pad was adhered properly.
[* black] In these photos you can see the pad was only partially attached on one side. The other side of the PCB was lifted several millimeters away from the bulb's base.
[* black] The bulb's metal base serves as a heatsink. You can see the air channels running vertically along the sides. This is why these bulbs should only be installed in a vertical orientation to maintain proper airflow.
[* black] Note the two Phillips-head screws in the central portion of the metal case. We remove these in the next steps.
