Depends on the stator. Most with power steering have to be 450 or 500 watts. A non-P/S machine would be in the 350-400 watt range. These are sized so that with everything on..all factory items..lights, gear (excluding winches), power steering at maximum assist..everything, then with the accessory circuit at it's maximum fused limit which is usually 10 amps, all but about 1% of the stator's output is used. So if you dedicate the accessory reserve and yours is a 450 watt stator, you will have about 14.5 amps to play with. I suggest keeping it to 12. A 500 would give a little more...and of course the chances of you using every "bell and whistle" on the machine at the same time is not really probable so...Also LED wattage output does not directly equate to the amp load the light will draw. For example, a 180 watt light bar would convert to using 15 amps...but it doesn't. It's actual amp draw is about half that.
