Small Rubber ring in downlighters box - what's it for?

[RL19]

Fitting Aurora fire rated downlighters and in box is a seperate small rubber gasket in a plastic bag. Cant work out what it is for as light housing has rubber gasket where it meets plaster board and nothing in the instructions. Is it a spare although looks too small? 

Cheers

Could it be a gasket for the lamp retaining ring?

Picture could really help your cause here....

On non-fire rated ones it holds the cable connector onto the spring / shell.

I thought it was for IP rating

fell out with them years ago as their warranty was as good as B & Qs.....did I ever tell you about

I thought it sealed the fitting against the ceiling?

It is placed between the edge of lamp and the fitting. 

You fit the ring within the front recess of light then fix lamp and pull lamp back into the light right up against the rubber ring the lamp is then held in place with a wire clip.

That was what I used to do with them...just assumed it was an IP thing, but they did have a nasty habit of poking down through one side and stopping the clip being fitted.then you remove clip, ring falls out and you spend 10 mins trying to find the damn thing
