That was something negative first, the delivery took a while and the packaging, let's call it semi-professional. Otherwise, if an outlet is not available, bring light very easily to all parts. Screw bulb and off you go. In my case, I use it in the kitchen as an additional illumination of the work area. I use the adapter with a LED light bulb and it works perfectly! Cheap product, processing mediocre but still Ok. Because the delivery time I pull from one star and for the mediocre processing another star!
