Hey Olddog! Welcome to my journal, glad you got something from it! It was New tricks for me for sure in that one! The folks at Vipar decided to not bring this one to market at this time I'm thinking. I didn't get a lot of information that way. Vipar did continue the form of it with the XS2500 Pro, their 250 watt model, down 50 watts overall.
I have a few lights for that tent and I'm sticking with these beauties! Those XS2500's compare I'm thinking.
I suspect it's very similar to the one
@CaptainLucky mentioned, the XS1500 times 2.
