There are a few different variants on the LED candle lamps from ebay. Most high output ones use a little switcher supply and high power LED, but this one uses a fairly beefy capacitive dropper running a circle of 9 surface mount LEDs at about 50mA on an aluminium core substrate. It's actual power rating is closer to 1.6W.
The neatest part of this lamps design is that when you attempt to unscrew it the cap immediately pops off and a live circuit boards dangle out in an exciting manner.
The construction consists of the aluminium cored LED PCB and a capacitive dropper PCB sitting loose below it with a bit of heatshrink sleeving used as an insulator. There are two support pillars inside and two not-quite-matching holes on the LED board so it's not screwed in.
The clear cap screws into the base and there is a friction fit lightguide inside that has a recess that suggests it is actually designed for single point high power LEDs.
I like that fact that the lamp can be gutted and used for the base and cap alone. It would allow you to make some neat decorative lamps like the DIY one I feature in another of my videos.

Not really an achievement, but … First?
