Does anybody have any experience with these flashes? They are known in the US by their rebranded CheetahLight name (CL-180/360). Esp. the 360 (Ws) version, although not cheap, seems like a good choice for on location shooting, and a viable alternative to the much more expensive (and lower in power) Quantum QFlash. It doesn't come with TTL or other higher end features, but it does seem well build and reliable. Also has a serious assortment of accessories/modifiers at very nice prices. I'm bringing up this subject of high-power, highly mobile lights, because I'm doing a study on a "studio on a bag" solution, that I'll be posting soon. Any experience with these lights would be greatly appreciated!
