A thing about the thermal/basking that people often times do not think of. Its People will just use 1 or 2 higher wattage basking bulbs and call it good.. When you want to use a concentration of flood bulbs across a larger area.. So if your covering say a 4ft by 4ft area (one of the top sides), then ideally you want anywhere from 4 to 6 bulbs to cover a broader range to fully reach all areas of the iguanas body, so there are no hot and cold spots.. Doing this your going to have to experiment on what wattage best suites you.. As well as the proper lights to use. You obviously need UVB light via either a long florescent tube or mercury vapor light.. But also what they "market" as full spectrum lighting.. But basically 1 or 2 bulbs between the 4.5-6.5 color spectrum.. They commonly sell metal halide flood bulbs at just about any store (and cheaper than pet stores).. These would do you just fine. This is commonly overlooked.
