Hello everyone, I'm rather new to digital photography and to this site which I find very helpful, I'm a hobbeyst not a pro and looking to buy a reasonably priced monolight, I came accross the Medalight PG600XL 300ws and it sounded real good and the price is right as well, has anyone here used it before ? unfortunately the manufacturer's website doesn't offer a whole lot of info, I couldn't tell whether the modeling light is a regular household light ? can you control the light in steps or stepless ? is it fan cooled ? I will appreciate the feedback about the performance as well as the features of this light, thanks a lot in advance
