I have two Shear Descents. There is no metal in them - its all plastic. Other than a ladder in the pool (not too common on IG pools anymore), what is going to corrode? The current/new model pool lights are designed to withstand SWG pools. Perhaps the builder is referring to seeing corrosion on older pools that were converted to salt systems or AG pools.
