Ionisation smoke alarm near fluorescent lamp

I'm fitting a (mains powered) ionisation smoke alarm on my landing ceiling; the instructions specify the minimum distance from the walls (300mm) and add that the alarm shouldn't be mounted close to a fluorescent fitting, because of the chance of interference. But they don't specify any distance; I don't have much room to play with.

Obviously, I could contact the manufacturer for clarification. Before I do, does anyone have any practical experience on a reasonable gap to provide?

The light fitting is circular, with a 2D lamp.

If the manufacturer do not specify a distance then it cant be be much of a serious issue.

I would ensure that you fit the smoke alarm >300mm away from the light fitting.

Thanks. I've managed to get it approximately 500mm away from the light, and still far enough from the wall to meet that requirement.
