How many total watts can I run through a 200 amp panel? 24,000 or 48,000?

To answer the question - a 200amp service is 48000 watts.
200amp at 240volt can also be thought of as 400amp at 120volt.
The total power from the panel is the same if divided by 120 or 240 volt circuits. The total power from the panel would thus power the same number of lights.
The best reason for running 240 volt circuits is to keep the load balanced between the two 120 volt lines that create the 240 volt service.

@Hookah79 If you are measuring each 120 volt line of the 240 volt service separately, then yes each leg can pull 200amps at 120 volt which combined is 200amps at 240 volt. One general rule is that the service can pull 200amps max. but continuous draw should be limited to 80% of maximum power.

Question for the experts:

My setup: I have a 220V 40 amp breaker with a 3 prong crow foot style straight blade 50 Amp outlet that is typically set up for a range oven.

(been hiding behind the stove for a while don't worry not that dirty now lol)

Q: I'd like to plug a spider box into the 220v 40 amp outlet so that I can run the max amount of 1000watt digital 120/240v ballasts as possible off of it. What would be to max I could run, ballasts draw 4.5 amps at 240v and 9 amps @120v? Is what I'm looking to do below the best way to configure this? How do the 120v plugs differ from the 240v as there is no option to chose on the ballast. below is a pic of the ballasts

Info: heres what I'm looking into for a spider box I know its a 40 amp circuit so I'm looking for a 40 amp spider box but they are hard to come by. Also, the outlets on the spider box can change if i get a different box just the concept of what I'm looking for then the box can change to fit the correct needs... work with me here plz :)

says has 6 125/250v outlets but how do you dictate the 250v vs the 125v as there is no option to select on the ballast either?

I then need to connect the spider box to the 220v 40amp circuit. Which cord would be best? do i need to change out the 250v 50 amp 3 blade crowfoot style outlet that is currently in the wall into something more common such as this pic below or what would be the best Configuration??

It looks like this spider box already comes wired with a CS6365 male ended connector

Any help to make it possible to best run/configure as many of the 1000watt lights/ballasts off of this 220v 40amp circuit breaker as efficiently as possible would greatly be appreciated!!! :) thank you guys!!!
