Just stumbled across a post from Alex Mustard, posting some photos taken with the new Retra pure II strobe. I have the Pure strobes which are 70 Ws rated and use a slightly smaller diameter circular flash tube which gets more of the strobe light entering a snoot. Here's a link to the post on Facebook:

Apparently shipping Nov 23. said to be their lightest strobe. Here is the info on Retra's website:

Curious about weight and what the "most compact" size reduction amounts to. Could be a great macro travel strobe for those of us who are

trying to cut size and weight for traveling and are Retra fans.
