Sorry if this was already posted in the forum. I have an aluminium heatsink and the Luxeon Led Emitter, and i'm wondering which glue do i need to use for put these 2 parts together? Remember i live in Argentina and we don't have the same glues you have there. If any can show me any pictures of the glue... maybe i can get one similar here. I think i can use regular contact glue, but maybe i'm wrong... Thank you.
