Installing a 500W bulb in a 400W housing in Pentair Amerlite

I'm only guessing but I'd follow what the manufacturer says, not a pool store guy who was out of what you needed and wanted to make a sale.

FYI if anyone else is looking for this specific answer: I was finally able to call Pentair customer support at 800-831-7133 for technical assistance on this question. The tech assured me that the housings for the Amerlite with the 300W, 400W and 500W bulbs are identical and that a 500W bulb can be used without issues. The original pool store guy and an employee from another pool store that I also asked who said it was OK were correct.

Good to know.

Thanks for posting the follow-up!
