Kinda - in that you also need the light hood/fixture that has the ceramic socket to handle the heat & wattage. You don't want to be using a shop light hood (plastic bulb socket) with one of these - fire hazard.
I order them 2 at a time. You'll need the 2nd one eventually and it saves on shipping.
About moving the iguana to the basement... iguanas need visual stimulation. Keeps 'em sane - so to speak. Is there going to be enough going on in the basement to keep your iguana interested?
If it is just getting banished to the basement to get it out of the way or the wife unit doesn't want it upstairs in the living spaces, you may as well get rid of it. Not fair to the iguana to get tucked away in some out of the way corner.
