It'll be fine, 4 ulbs do NOT have enough heat to heat up that MASSIVE pool of yours. You sure it's 32k gallons? You'll get plenty of condensation in the winter since the water will be much colder, so tap the bottom of the IB's to drain them. Also, scratch the pump... use your existing pool pump and get a three way valve plumbed in. You should adjust the pressure in order to send a part of the out put of the pump to the IB's. I would tap this on your return line to the pool (right after your filter) Good luck, post updates! P.S. remember you want your water 10 degrees colder then your room temp. In the summer, if the pool gets hot, it's not the lights. You may still need A/C but the requirements would be a lot less then trying to cool the room, plus the lights with with just air.
