This. In particular, I'm concerned by the little switchmode power supply on a non-user-servicable board potted into the depths of the bulb.
If that 5c capacitor dies, a $40 bulb gets scrapped even if everything else is still good. Hopefully Phillips have designed around that, but 20 years is a long time and they have little incentive to do so.
I suppose a proper, universal, standard for low-voltage DC in houses (ala 12v Halogen downlighting only universal, something like PoE) is probably too much to hope for.
