In most of this style of lamp they tend to push the LEDs quite hard for maximum intensity, but this one is using a nice sensible 200nF series capacitor. this should result in good lamp life.
There's no electrolytic for smoothing, so the lamp will have a some flicker to it in peripheral vision, but that makes it simpler and better suited to general lighting in areas that are not occupied continually.
This lamp is based on a fairly traditional style, but seems to have been refined a bit over time. Particularly with regard to the way the PCB clips in.

I did a Google search and couldn't find a web page for Dodgy testers. Am I misspelling the brand name?
Her bigclive have you ever gotten a "wake up surprise" from a capacitor
Like it ,better than over doing it..
I replaced a 330nF capacitor with a 220nF capacitor and the LED bulb I had repaired few years ago failed to turn on so I restored the old one back (it could be that the only 220nF capacitor I had salvaged some time ago is dead). Although larger smoothing capacitor 6,8uF 400V from broken CFL did smoothed better and enhanced a bit of the light output. The bulb is unknown salvage with a "Chinese Export" sticker on and it has also 38 5mm straw hat LED's with quite small emitter area (roughly the size of the daylight LED emitter). Thanks for sharing.
what are the type of clips called for the dodgy tester?
Adding a smoothing cap would increase the voltage (though that could be compensated for)
Have you ever thought about having a lightly scrunched piece if alu foil handy, just place the back of the board on it to discharge all caps 😉
Where did you acquire the lamp from and how much did it cost? Many thanks
