Mixed Recessed LED Lights Not Working

I purchased a home that has recessed lighting throughout. They are the LED lights that clip into a standard light bulb screw-in socket. They all point straight down and I wanted to purchase some that gimbal to highlight some artwork.

All of the existing lights are 10w 120v/60hz.

I purchased a 15w gimballed light and tested it in a bedroom and it worked fine.

However, when I installed it in the main room where the artwork is, it would not turn on. I tested two different fixtures with the same result. I then tested the new light in the kitchen and it worked fine in there.

The main room has a total of 12 lights where the other rooms I tested only have 4. This is the only difference that I could think of between the two rooms.

I ordered a 10w gimbaled light to test but it just seems strange to me that this is the problem.

Anything else I haven’t though of?
