Pool Lighting

I have a 20X40 Pool that has 4 fiber optic lights the size that fits into a water return size fitting.  I know you can replace this with fiber optics, but I would like to know your product recommendations.  I’ve never be satisfied with the fiber optic lights because they have never been very bright.  I’ve heard the LED lights are much brighter, so do I need 4 lights?  Basically, which light do you recommend and how many?  I’m going to replace my liner in the next month and I want to make the change then.

Thanks
