Hey Baja. Where are you located?
I'm in NY and all my christmas cactus go out in full sun all summer long no problem... i do acclimate them on my porch starting with morning sun and gradually increasing exposure, but by June they're out.
I have accidentally given them a really bad sunburn going from the livingroom window straight to the patio, but with gradual increase I have no trouble at all, and the ones in full sun tend to do better- they grow more and have more blooms come fall. Maybe its location?
