Baja CA, Phoenix AZ, Reno NV--the sun in these places much stronger than anywhere else in the country like Midwest and East and even the South! Schlumbergera need shade in the afternoon to survive. Here in Phoenix the humidity yesterday was 5%!!!! I struggle with Schlumbergera as you might expect. I only put them outside for 6 weeks in late Oct./Nov. to get the cool nights to help them set some buds. It is very difficult here though! You can see a Rhipsalis to the right. That died. Not enough humidity here! This Schlumbergera gets little direct sun and you can see the leaves show intensity of the light on it.
