since I got a chance to use both teh Calumets and the DLites, I'd go with the DLites for 2 reasons.
1) easy to understand controls for changing power output
2) smaller + lighter construction.
the Calumets were amazing lights as well but they're substantially bigger then the Elinchrom counterpart.
We used cheap $19 Impact lightstands on the DLites + big softbox with any issues for 8+ hours and I wouldn't hesitate to do that again. We tried a calumet on it and it was just too heavy for the lightstand.
My personal opinion is if you plan to carry the lights around, get the DLites, if you plan to keep them stationay or minimal movement then the Calumets are great too.
a lightmeter is easy enough to use to figure out what a full stop is on the Calumets so thats not really an issue cuz if you're using studio lights like this, a lightmeter makes things worlds easier to setup.
