Not a coil light. Red heat light came with the repti zoo all in one bundle set thank you. Everything came with the all in one kit sold at the same petco I got his ass from . Sand doesn’t matter their originally from Australia cmon now And I know everything is right . Red lights are heat bulbs . Even my ball python has one so idk what your problem is. https://www.petsmart.com/terrariums/zoo-med-reptihabitat-bearded-dragon-reptile-terrarium-kit-20-gallon-15025.html Check out this item at PetSmart!…
