HID Ballast Selection 50w?

[Exhausted]

I sold my 2013 Ram and came back to a 2015 Silverado, when I did I took off my HID kit from Morimoto because it was the same one for the current Silverado's

I have the 5000k bulbs and 50w ballast but have a question for some that might know.

is the enclosure for the Silverado projectors to small for the heat output that the bulb will have due to the 50w ballast?

I need to get H11B bulbs anyway but if these are to much I would get 35w ballast.

thanks
