| + | [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. |
| + | [* red] 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. |
| + | [* orange] 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] If you plan to re-assemble the bulb, you should scrape off all the old thermal pad from the PCB and case. Both surfaces should be clean. Replace it with a good thermal adhesive epoxy, following the manufacturer's directions. |
| + | [* green] Note the two Phillips-head screws in the central portion of the metal case (marked in green circles). We remove these in the next steps. |
