  No that's a different lamp, but Clive did a teardown of that one too.[0] Compared to the Dubai lamp it still drives the LED filaments at 0.25 W each, but the driver circuitry is traditional and doesn't have the unusual features from the Dubai lamp. These include component-level redundancy and automatic brightness compensation (this breaks dimmers, so architects hate the bulb mandate). Nothing ruins a nation's (carefully cultivated) high-tech luxury image like all the bulbs dimming simultaneously with the grid voltage!
