That's a different lamp. Clive did a teardown of that one too.[0]

Compared to the Dubai lamp it still drives the LEDs at 0.25 W each, but the driver circuitry is traditional and doesn't use the unusual design from the Dubai lamp. These include automatic brightness compensation (no dimmers!) and component-level redundancy.

Nothing ruins a nation's high-tech luxury image like all the light bulbs simultaneously changing brightness with the grid voltage.
