I bought four of these for use in a small local hall, used for small productions. We had no real theatre lights prior to this. We bought it along with a DMX controller. The lights were well packed, so no problem with transport damage. What I liked about these, from a safety aspect, is that they were a bit lighter than expected and came with a place to attach a safety wire. Once installed it was easy to program in the DMX addresses and connect to the controller. They have 7 functions in DMX mode: Red, Green, Blue and White intensity, a master dimmer, a strobe effect and a built in 'automatic show programmes'. It also has a twist on connection for the power cable, so no fear of the chord being disconnected.
