Cree XP-G R5 20mm triple lense?

[ceefna]

Hi all, my first post here. I have a little project on the go and wonder if any of you know where i can get a 3-up narrow/spot lense for a 20mm triple XP-G R5 MCPCB preferbly from the UK. Have googled but only found them in the states or in the quad led form.
Hope you can help
