I just put Halo Recessed lighting in my kitchen. I had to use the remodel style cans. Because of some pipes in the ceiling, I had to use three shallow cans. I used the 310 trim. I used the short neck bulbs in the shallow cans and the long neck bulbs in the larger cans. I have already tried to adjust the inside of the cans also. My problem is that the short neck bulbs in the shallow cans hang much lower than the long neck. Does any one out there have a solution to this problem.
