I need to study up on the Elinchrom product line. Ideally I'd like more power than the D-Lite 400s, but then again, with HSS i could kill the ambient much more easily, which means I could open up the aperture more, which means I wouldn't need as much power in the first place. Hmmm.... The RX 600 heads are too expensive for my budget, but very appealing.
I'd be tempted to try to run these off a Vagabond since the Elinchrom power supplies are so costly.
You might have to go with the Elinchrom power supplies. Not sure which you are looking at, most I see from them are digital and if you are looking at the Vagabond Lithium Mini, it may not work for you as you think.
The Lithium Mini is really designed for analog monolights and because of the way it recycles, it creates issues with digital lights. As an example, I cannot run my Photogenic PL2500DR or PL2500DRR off of the Mini... even just a single light, which technically the Vagabond should handle.
I can, however BARELY use the Vagabond with my PL1250DR, so only 500W/S versus 1000 W/S and even there only single light.
Now if I was using the PL1250 (Analog version) I should be able to power 2 fine.
This is something to do with the inverter, the voltage drops during the recycle and the stable power needed by the lights. The digital lights for the most part have a slightly higher requirement and at the bottom of the curve, the Vagabond is too low and "brownout" can be harmful to the digital components
You also notice all the Paul C Buff are analog. Not a coincidence.
Would be nicer if the Lithium had a little higher curve, but it is optimized for their line.
