This is a totally personal opinion but I'd go with DHPs and let dim natural light signify the day/night cycle for an albino.
Remember, even for a Royal python that is not an albino, their light preferences can be described as 'outdoor shade on a sunny day'. Now take your albino and dial that down significantly.
Again, this is just personal opinion - I only have one albino snake (a Hognose) and he most definitely shies away from any sort of direct light, but loves basking on warm rocks under a DHP.
