Good stuff according to price. Surprisingly for me - using lens/focus adjustment you can get almost uniform color filling even on the edges of the light spot. I expected higher visible light output, but you know - you always expect more. :) Obviously there are some losses because of optical system. You should be ready, that hanging brace pretty weak (according to the price!) and does not conform to standard trusses hangs with 10 mm bolt. But obviously these lights are not for professional use as main lights. Fans sound is acceptable if there is even low music environment, but can be annoying for people like me if you want to use it at home in silence. One more thing you should notice - power cable is only line and neutral, without protective earth, so, as it is noted in manual and on the label, don't use it outside. PCB looks pretty well assembled inside, works as expected. I bought them as SUPPLEMENTAL lights and for this job they fit very well in my case.
