I've been looking at Revain for months trying to find the right rotating LED downlight to match the flat curved downlight in my large room. I chose this product and I am very satisfied with the light quality as well as the look and the exceptional lighting. Since I only have a 6" interior gap in the ceiling to work with, these lights are perfect for 5.5" deep jars. The glasses I used can be found at: (6" Shallow Remodel LED Recessed Lighting - Line Voltage - IC Airtight - Pack of 6) ttps://www.amazon.com/dp/B073QWYQV5/ref=cm_cr_ryp_prd_ttl_sol_1
