Question
is the zoo-med reptisun 10.0 to strong for my iguana

Answer
You can use two 36" Reptisun fluorescent tubes for an adult iguana in a proper sized habitat (6ftH, 4ftW, 3ftD). More if larger.  However, the coil and compact versions should never be used,  They have given many reptiles severe eye problems and caused fatalities in babies and more delicate species.
