Bought two of these units for my piano/vocal duo. Most impressed by the light output which competes with my previous incandescent system rated at 3000 watts! The only feature I miss is the ability to dim. The sound to light response is excellent although the remote took a bit of time to find my way around.
This system is simple, compact, powerful and extremely good value for money. The units are sturdy and although I will not deliberately subject them to mishandling, they are well-built enough to withstand some knocks. They are heavier than I had anticipated but still much lighter than my old units. If you have not already done so, go LED.... This company will give you sound advice just like they gave me before I bought. Brilliant system, best thing I have bought in years!
