I've bought almost 200 of these. They are relatively easy to install. I personally attach the cabinet bracket (new design) first so I can position and temporarily light it before the ceiling comes up. I don't know how long they last a month. The light quality is excellent. The brightness is excellent. Adjustable 5cct modules are good but personally I think 3000k - 5000k is too bright for 8ft ceilings. They seem good for 9ft ceilings. They are suitable for low profile situations, I was able to place them under the joists next to the truss (3/4" deep). You can just replace them with another single color light. Likewise you can't use a 3cc lamp simply replace with a 5cc bulb, this is why I recommend 5cct if you are unsure of the color you want for each room and if you are sure of the color you know, buy individual colours.
