I was very hopeful that these would illuminate a dark area in an old house kitchen. They have done that but here’s my take 
Pros easy to install- either with screws or stick on tape provided. 
Cons I realised that these used batteries instead of plug in electrical for power before I purchased. Each light takes (3) Double A batteries so 9 of them to install. 30 days in and I have had to replace 2 of the lights battery packs all ready. Suddenly they are dimmer, dimmer than out. This is using them for about 2 hours a daily. 
The remote is a nice feature, and it worked well at first but suddenly it is not responsive unless you are very close to the lights. 
I wouldn’t buy these again.
