Hi all: I'm lighting a dance show in a few weeks and they need strobe lights for a couple numbers. The stage is pretty large (55' long by 43'5" deep and 31ish feet tall - although the front is a thrust) Anyway, I was wondering if anybody had any experience with the Chauvet Mini Strobe LED. Do you think 4 of them would cover the stage? Also if I control their power supply through our Express board they should sync up, right? If these fixtures wouldn't be suitable, can anybody recommend anything that would suitable? I'd love to buy if the cost is low enough, but I'm also happy to rent. Thanks!
