Review on Onforu 4 Pack LED Black Light Bar: 24W Plug and Switch, High-quality Glow Party, Stage Lighting, Body Paint, Fluorescent Poster, Birthday Wedding Party accessory with 5ft Power Cord, IP66 Protection by Steven Lane

I like that they are easy to adjust - I've had 4 glowing Zumba parties already. I mounted them on the walls at shoulder level and below, placed them on the floor, and hung them from the ceiling. I was able to rotate the light at different angles from the base. I bought two sets (6 total) which easily illuminate a 20 x 30 foot room well. I used command strips to mount them. Two complaints: 1) after installing the brackets, they no longer fit in the box, and 2) the brackets on two of them were ripped off and would not tighten.
