Review on VOLISUN 12 Pack 4 Inch Led Recessed Ceiling Light With Junction Box, 5000K Daylight, 9W=75W Canless Wafer Downlights, 750LM Dimmable Retrofit Recessed Lighting, ETL And Energy Star Certified by Tim Pulse

I bought two of these 12 packs and installed them about two months ago. I have not had any issues, no flickering, no temperature differences, none were DOA. They are as easy to install and as nice as my friend's brand-name lights, which cost $130 for a six pack from the local home improvement store.Pros:1) Incredibly bright. After a lot of thought I spaced them further apart than recommended, and overall fewer lights than my space "should" have, but I almost feel overwhelmed with these turned at half brightness.2) The temperatures are consistent across the lights and none flicker when dimmed.3) Super easy to install.3) Work well with the switch throttle (terminology? I don't know these things) to limit minimum and maximum brightness. Have not noticed flickering at any level. 100% is VERY BRIGHT.Cons:1) Momentary delay when powering on. I may just notice this because they are in a large, generally very dark basement, and I pause at the bottom of the stairs until they are on.2) The junction box is very thin metal and deforms easily. I have two with three romex sets in them, and had to be careful where everything was positioned to allow the box to close.
