Lights come with dirty optics from inside the light (all 8 from 8 pcs). Good thing is, that there is some random dmx cable inside. There are no normal handles on the light - you are unable to hold the light in one hand, it is bad for manipulation. The fan is not much quiet, but that is understandable. Problem is, that there are just really small holes in the body of the light (and in wrong direction to the air flow), that the air from the fan does not flow out thru the proper holes but it tries to go thru all slits and leaks in the light .. and takes the air with all dirt and smoke to the main lens - where the dirt is applied to the lens surface.
