Can I use a 60 watt halogen bulb on my iguanas cage?

Answers:
Hi,
It depends on size of the cage and the size of the iguana.
Like the first reply, you must supply a UVB light source like the sun unfiltered or special lights that provide UVB. An iguana needs UVB to survive. Check this web site for ig care:

Digital temperature gages are best to check basking temperatures.

I think so, but it won't offer him the UV rays he needs. As you probably know cold blooded lizards need a certain temperature heat as well as so many hours of UV rays to survive. A 60 watt halogen bulb wil offer only a little warmth and basically only be a good source of light.

The size, or wattage, of the bulb really depends on the size of the cage (or tank) that the iguanas are housed in. For smaller tanks, a smaller wattage bulb would be needed, and for larger tanks, a larger bulb is needed. (i.e. 20 gallon tank=50-60 watt bulb; 100 gallon tank=150+ wattage).
