I have the older version and the new version of this light, the current version seems significantly brighter than the old model, not sure if that is due to LEDs losing their brightness over time, the old ones are about 15 years old I think.
I use them with control software (ShowBuddy Active), and they are very controllable with a decent dimming curve.
The built in programs are useful and very editable when needed, not a huge variety but enough for most purposes.
Used as front light 2 of these are fine for a 6m wide stage with 3 performers, but on a bigger stage with more performers we need more, or brighter lights.
We have also used them upside down as ground standing effect lights and they work well in this format too.
The yokes are a little flimsy, but adequate, and the case is excellent and well padded.
In summary, a great value, useful fixture.
