Camellia are lovely, fascinating trees. And they are adaptable. My biggest problem with wintering Camellia indoors, under lights, was that I had too many plants, and had difficulty keeping to the watering schedule the Camellia needed. It needed more frequent watering than the orchids, and got too dry, several times, while in the orchid collection. As a result, it failed to thrive. But if you can keep on top of the watering, there is no reason the Camellia won't survive in your light garden.
In the future, leaving it outdoors in autumn, until serious cold threatens, may be sufficient to set flower buds, and you may be just fine keeping it indoors for your future winters.
