Received in time, I congratulate myself for having placed my order. For interwiews, or internal reports, the implementation is fast, and the lighting is adjustable at will with cold lamps, hot, (Hypermarkets, etc ..) Just observe and do not exceed the recommended power . Well, this case not long bear the manipulation's, but that's not the main thing. We can do a good job with a note of seriousness, 'very professional' for the curious with a camera !!!!
