I tore down the 600lm 230V version and it’s totally different. The driver is potted and the supporting ring/heat sink is metal. Also, there are many small SMT LEDs arranged in a few parallel strings of about 8 series LEDs each. Also interesting, it’s marked as 230V but seems to work fine at 120V. Clearly much more robust design than what you show in the video but the price is £6 ($8.50 US right now). Despite the more robust design, I have had a few fail when the heat is contained in the light fixture. The driver circuit fails but leaves me with a nice heat sinked ring of LEDs to play with.
Note: I was looking at an IKEA Ledare, not Ryet
