Will all my lights overload my charging system?

This is my first Jeep, and I'm going to light it up.

I have a good understanding of wiring, relays, switches, etc but I am wondering about overloading the charging system/battery if I run all of my lights at the same time? Obviously, that would be a very unusual situation, but you never know what may come around to demand it.

I am going to run:

2-KC Apollo 100w driving lights
2-KC Apollo 100w fog lights (are these overkill? Are the 55w adequate?)
and of course, the factory headlights

It is my understanding that the 1998 TJ came from the factory with a 90 amp alternator. I'm thinking that this would be adequate for my application unless I made a habit of it or ran all of the lights for an extended period.

Any electrical guys out there that can voice an opinion?

The easy way to do it is to add all of the power of your lights and just make sure that there is enough power to keep your battery charging. If your not sure when you do hook them up run your engine at about 1000 RPM the put a multi meter on your battery if it stays steady at around 14V then your good!

Instead of running 4 driving lights save the cash for Trucklite led headlights and some Rigid Industries led light bars. They are insanely bright.

Thanks for the opinion, but that's not the "look" I want.
