Comments about Profoto AcuteB2 600Ws AirS LiFe Power Pack:
This power pack is great! Combined with the strobe head it's perfect. For years I've been working with the on-camera flashes trying to rig them so I could use them off camera but I was never happy with the quality of light or having them work consistently. The first time I used the Profoto system I was kicking myself for not get it sooner! It was great to have a great quality light, that fired every time. My advice is to get an extra battery, after about 300 fires the battery will be exhausted.

Primarily used for location, but works equally as well in the studio. Light weight and portable.

Comments about Profoto AcuteB2 600Ws AirS LiFe Power Pack:
This is a great portable supply of power! Coupled with the acute B strobe, I use this to overpower daylight (key-shift) while on-location with my wedding couples. With a 2x2 softbox, it almost has enough power to overpower the sun, but without the diffuser, no problem. I wish this was available in the USA as a kit. My gripe is that at this price, it should come with some sort of case. This thing is designed for portability so why not include a case?
