Here is another LED disk light offering at Amazon that looked promising despite a rather high price, $42.99 each. It seems pretty enough. Shapely. I assign a product number as the second set of digits in the box bar code.
The packaging is simple and compact.
The thin lens is engaged with three loose-fitting keys. I reported in my Amazon review it hardly wanted to stay on. All such lenses admit bugs at a slow pace at their periphery. For most installers, the bug problem will be from backside access through brightly lighted keyways that can not be covered, unless the junction box is perfectly sealed to ceiling spaces. My greater unhappiness is with the absurd single diode.
Diode and array luminance is thoughtless and mean. Cheap.
This light kit has one really large virtue. See the steel segments provided, called Adaptor Plate. This plate is what we need to grab box screws at 3 1/2" pitch, where petite luminaire holes are at 2 3/4" pitch. This is much better than ring adaptors mentioned for luminaire 4" GetInLight .
This is really nice. Sturdy.
With the awful glare problem, I see no reason to put up with bug prevention measures only I can take using my flexible grout and RACO 175 boxes. Others have not yet admitted the challenge, to seek a solution. We must not tolerate bug fouling in luminaires that may else be maintenance-free forever.
