If 2 AB 400's are fired simultaniously at full power does the output equal that of 1 AB 800 fired at full power?

If 4 AB 400's are fired simultaniously at full power does the output equal that of 1 AB 1600 fired at full power?

If the answer to this quesion is yes than If 2 AB 800's are filed simultaniously at full power than it would equal that of 1AB 1600 fired at full power> True?

just guessing here but the entire output should be equal. but what's the point since they will prolly be point at different spots at different locations. so you're not really dealing with that ab800, just in total output. it would be kinda hard to have them on the same exact plane, same exact location, and same exact angle...right?

Assuming the maths stacks up it should, but it wouldn't be anyway as near effective as having separate, individually controllable heads, that can be positioned to direct the light onto the subject from different angles.

Yes, if all the lights were all together and aimed at one position. It is common for professional studio strobe heads to come in a 'bi-tube' or 'quad-tube' configuration where all the flash tubes are together in a single head. the Bitube is double a single tube in power, and the quadtube is 4x a single tube in power. (BTW, each tube is powered from a different source...if 4 tubes were powered from a single capacitor, they would merely divide the available power between them, and collectively only be about a single tube in output!) Since AB are monolights rather than pack + heads, it is simple...the lights are all additivie, as you surmised.
