I have only been testing the device. For a supposedly 50W LED I found the light output significantly too low. Subjective impression. I also found the effect even now not so great. Changing the lens is awkward, loose packed glass lens is also at risk of being damaged. Finally, you can see only on site, which lens you need (except of course for permanent installation). Was tested by the spot lens at wide angle, the light is naturally darker.
The device is quite heavy, the mount for me very impractical.
In contrast to the current Amazon description of effect has not integrated its own music management!
