Hi @MjwardThe sole thing steering me towards non integrated is that I've become from a place with a Philips Hue setup and just absolutely loved the functionality you get with those bulbs. Cheapest way to set scenes/light automation etc. 100% if that wasn't on my mind then these integrated LED units look far superior to what they were 10 years ago
You may find some of the Philips Hue lamps don't fit in all downlights. I would recommend speaking with the manufcaturer first to confirm. Otherwise you could end up dissappointed.
All the best.
