Yes, those are the bulbs! They experience quite low temps in the wild, personally, I would try not to let the lowest ambient (in their hides/burrows) get below approx 20c (68f), or a little higher.
I kept the very closely related Ornate monitor (a separate species), for 14 years, though they prefer somewhat higher humidity than Nile monitors, and slightly higher nighttime temps.
