Pool light buld question

I have spent hours and money replacing gaskets etc but still get moisture in and keeps ruining expensive LED bulbs so going back to old fashion spot light. Would love a blue one if made.. This is about the 3rd LED bulbs and new gasket and its breaking the bank
I just took it out and no standing water water but electronics and moisture don't mix

Question is can I buy a standard 120V 300 watt spot light bulb or are pool bulbs different??
