This is a amazing pack with fast flash durations.  Not far off of the Scoro at comparable power levels.

Travels well. Lightweight and nice size. Flash count is 26K , which is very low for this type of equipment. For comparison, I just bought used Scoro packs all with around 100K flash actuations.  

I have shot everything from table top to celebrity fashion jobs with these packs and they hold up.  I have more available in 3200 w/s and 1600 w/s 

I honestly believe that Grafit packs are the best value for the money out there.  Compatible with nearly all Broncolor heads and accessories 

Please reach out with questions.
