I've had an older Philips wake up alarm for maybe 7 years now. Not sure how long the new one's last, but the my old Halogen model has been used for several hours a day for 7 years without needing a bulb change.
Yes! I love my previous generation tapered conical Philips hue. Don't like the look of the new ones though, so I'm not sure what I'll do if mine bites the dust.
Seconding the Philips wake up light. They're rock solid and have a capacitive front for snooze which is nice(just wake up and tap the front face of the light to make it stop alarming for a bit).
