Black line around emissive material vray

Hello! I have this issue where I have a lamp, a cylinder, that I have applied an emissive material on, and for some reason there is always a black line around it and I cna’t figure out why. I have used emissive materials before without the line appearing. Please Help! This is with Vray 3.6

Have you tried remove the emissive material and instead making the lamp a mesh light? If all else fails, upload the model, or part of the model with the light so myself or others can take a closer look.
