The dimensions of the lamp are very compact and about with a 10 "to compare Tablet - but about 3x thicker Also, the weight is also absolutely fine and is likely to be without battery at about one kilogram to paper over the YN-600 LED Video Light.. also easily stowed in a better photo backpack!
The operation is very simple and easily understood instructions within minutes. On / off, brightness of the two LED groups (3,200 K, 5,500 K) Set in 1 or 10-percent levels, channel selection for the remote control - done. Because you can control the color temperature very nice, you always have without similar due lighting while using filters need to handle. For me it was for example, 99 percent and 33 percent of 5,500 K 3,200 K to a bright but also to the environment to create suitable lighting for indoor shots. Perfect!
Conclusion: For the price you can not ask for more! The maximum brightness is top, the adjustable color temperatures a very nice feature, the built-in fan starts only after a long time at all once (then also audibly) and the remote control for three channels also a nice addition. I'm going to even the YN-300 II set, based on the good experience, for use on the camera.
