The light output is really awesome and video recordings succeed so well.
The tripods are appropriate for the lamps, the cables have a reasonable length, although of course you need a cable drum in most venues.
The bulbs are well protected by the original packaging, so far are all healing, the lamp socket make a stable impression. Overall, the workmanship is good and stable. Very adequate for this price in any case, who may pay twice or more per lamp naturally expect more.
