I have a Lencarta 300W Flash Tube for the ElitePro / UltraPro 300Ws Version 2 (current model) only
I bought this for my ElitePro flash but its prongs only fit the new Version 2 flashes (The ones currently for sale on Lencarta's website). The prongs are slightly bent (due to not fitting my ElitePro version 1) but they should fit fine into a version 2 light and have no effect on performance. The tube has never been used so is basically new. These cost £50 on the website but Im happy to sell for £35. Message me if your interested, Thanks.
