I wanted to run my Elinchrom D-lite 4s outside.
I did not have enough money for the portable power supplys that are meant for this, from my understanding the cheaper ones just don't work with the D4s. *sadface*
But thats okay, because this UPS does ! cost : 120$.
Aaaand it works, even fires both of them at full power !
Drawbacks include, weight, safety turn off features if the flashes are fired too quickly.
And no portability... which is what i wanted this for Right ?
So with that onto step 2: [link]
