I know this has been discussed way to much but I am having trouble figuring out the information I need. I will try to be as specific as possible.
I will be ordering this weekend either the 1250, 2500 with bi-tube heads. But I just can not wrap my head around the flash duration discussion that has been going on.
Now if I were to purchase the 2500 pack and use the bi-tube it looks like the T1 (only number I care about as that is what stops the action) is at 1/600th of a second which is the same as the AB1600 I currently own. That is with both plugs plugged into the outlets.
Now if I were to set that to the 1/4th switch would my T1 now be 1/1250th at 625ws (same power as the B1600's)? Or what would that be at?
I know that by lowering power using the slider my T1 would actually get longer and not shorter, but that I need to use the switch that is located next to the plugs in order to quicken the T1 flash duration.
My question is the same with the 1250 pack. If used at the 1/4th switch that would be 312ws (same as a B800) and my T1 would than be 1/1800th? Or what would that be?
The only numbers I really care about are the T1 numbers. Would it be better to just get the single tube heads if I will be using these packs on 1/4th all the time or will using the bi-tube still be quicker on that power setting.
Or what if I had the bi-tube and only one plug plugged in and have it on 3/4ths setting (is that even possible) would my T1 be better?
Sorry for all these questions. I have to have these by Tuesday so I will be overnight them and I just want to make sure I know all of this information before I decide on a power pack.
**Wanted to also ask when you use the extension cable how much longer does that make the flash durations? Or does that only affect the recycle time
