Very modular design. You could perform a non-destructive disassembly. Yikes! Is that right? Turns out, it is. This LED fell off during disassembly. They are not hard to get off but I wonder if this one was loose and could have been the cause/contributing to the issue the bulb was having. Interestingly, no heat sink compound was used between the heat sink and the LED substrate. This part was in the center of the heat sink. The bottom contacts made contact w/the driver board and the top contacts w/the LEDs. Could the discoloration on the silk screen labeling be a sign the board was getting to hot? Good quality, high temp rated CAPs There was a lot more of these white cruddy spots on this inductor before this picture was taken… Not sure if this is an indication of an issue. Some crud around the right lead of the primary capacitor. May just be left over from manufacturing. The cap looks fine, no bulging or signs of leaking.
