Large Outdoor Christmas Lights Outdoor Christmas Lights?

Outdoor christmas lights? - large outdoor christmas lights

I have a deciduous tree, large enough in my garden, I would like to decorate with colored lights. The most that can be found in the 300 outdoors. I think it would be much more. Does anyone know where I am this (live in Northern Ireland to view Web pages), or have experience and advice they could share with me, you could get it?

Thanks
