LED lights

This isn't a fishing report but fishing related so I've posted it here. If it needs to be moved I understand. We do quite a bit of night sharking during the season and an occasional overnight tuna trip. I currently have two Halogen spreader lights mounted towards the stern and was planning on swapping them out for LED's. Boat is a 27 Grady. Does anyone have opinions or recommendations regarding which type LED is best or how many I should consider installing. I was thinking about two mounted in the rocket launcher towards the stern and one each on port and starboard.

I'd appreciate anyone's opinions who may have made a similar change or has some perspective. I know the LED's draw quite a bit less charge and from what I understand throw off a stronger light. We currently carry a Honda generator, two flood lights and gas to fish the night and was hoping to replace the need for carrying all that with the right installation.

I appreciate anyone's help with this in advance.
