I grow D. Regia outside in the sun, It is covered with a 50% shade cloth and grows in a glazed ceramic pot. The plant gets about 4-5 hours of morning sun. The temps have gone up to 110 F this summer and it has not flinched. I do like to top water my plant with refrigerated RO water, especially when it gets really hot.
My Cephalotus grows indoors under a grow-rack. Temps go up to 89 F in the rack. I have also got a small computer fan blowing air into the rack to get some good air movement in there.

Spintix357, here is my ranking based on year round 75-100F temperatures in my ultra lowland conditions.
Cephalotus - grows at my balcony year round but dies back during the hottest season
D. regia/Cobra Lily - cannot be grown outdoors without night temperature drops
Just to highlight that my problem for these plants is the lack of a significant night temperature drop coupled with ultra high humidity. Cephalotus is most forgving but if I push my luck, it won't survive past 2 years in consistently high heat day and night. Also, pots are preferably to be kept cool for Cephalotus as well as the other two species.
