Costco has the retrofit 5-6" LED dimmable 14W ( 75W replacement) 2 pack 2700K for $2.99 After Rebate, There is a limit of 12 per purchase but they told me I can just go back in line and buy more. it comes with option to hardwire direct or has a screw in adapter.
The light is nice and bright and although the trim is a bit wide it is flush so has a nice look.
Also the tax is Pre rebate so 12 boxes 24 lights comes out to almost $50
P.S this is in NJ not sure anywhere else-
