Youtube Summary

The smaller lamp bases often make it hard to fit decent drive circuitry into an LED lamp. Many manufacturers skimp by just having a low voltage ceramic capacitor and rectifier. But Philips have put some very interesting circuitry into this lamp.

Because they're under-driven, they actually need considerably more (typically four times as many) light emitters than a cheaper alternative, and those cost money. It's true that a capacitive dropper is a cheap way to make LED lamps work, but that's how the LED lamps you're offered in a typical store today already work, so doing that isn't saving them money over competitors, and since it's a long-life product they didn't skimp on the power supply design, check this Big Clive video for example:
