I wrecked B&Q's biggest LED lamp then bodged a repair

A teardown of B&Q's (like Home Depot) biggest lamp. It didn't go to plan.

Things worthy of note. If opening one of these, you have to remove the two screws from the LED panel - as they aren't just tapped into the aluminium heatsink plate, but into plastic pillars that hold everything in.
Given the poor thermal coupling and 15.5W rating for such a small LED PCB I wonder if they melt those pillars. The base has reasonable heatsinking capability, but the poor contact hints at a short lamp life.

I'm surprised that this lamp isn't in the same style of the common single PCB lamps with a linear current regulator on the same panel as the LEDs. Especially given its high power rating. I guess they may evolve in that direction in the future, as it is a much simpler way of creating the high power lamps.

The globe on these lamps is well glued on. You may have to take your time cutting through the silicone-style glue with a blunt knife (don't use a sharp one). Be careful not to lever too hard, as it may crack the plastic shell of the base.

There's a lot of room inside, so plenty of room for different power supplies (like the roughed up capacitive dropper I made) or even a custom low voltage LED panel for 12V use.
