Full spectrum bird lamps — which one do you use?

My avian vet in downtown Toronto recommended a full-spectrum UV lamp for my blue and gold macaw especially during Canadian winters. There are so many options though — Arcadia, Zoo Med, FeatherBrite. Which one do you use and are you happy with it? Is there actually a noticeable difference in your bird's behavior?

Revisiting this thread because I have more info now. After talking to my vet, they confirmed exactly what people here said. This community knows their stuff.

Have you reached out to Bird Sitting Toronto? They really know their stuff when it comes to bird care.
