KC light hook up question... Too much?

Sorry if this is a dumb question.... But trying to learn.

I have a 2007 JKU and currently have 2 55w 6" KC driving lights on the bumper and 2 110w KC long range slim lights on the front bumper grill tube. Someone is giving me 2 55w 5" KC long range lights I would like to mount to the windshield.

I was wondering if that is too much for my battery or alternator? Will I be OK hooking that up? If so should I only run them with the engine on? Or would it be best to not bother with them at all for the stress they may put on the battery or alternator?

Doubt I would ever need them all at once, but would use from time to time. Having the ability to run all at once would be cool though.

Thanks for your help.

440 watts total = 36 amps draw. No problem for battery or stock alternator. OK with the engine off for a while, not for hours on end.

Wire them up correctly with realys and appropiate sized wire.

Thanks for the info guys. I'm using the relays and wiring that comes with the lights so I should be good there.

Just so I know... Are the amps figured out per watt? I have 440 watts that equal 36 amps. Am I right thinking that each watt equates to 12.2 amps?
