Ultra do your blades have tip bloom? Or the dim spot?

I really need to try to get suma dose mirrors. I live in the UK so I can't go to Wally's World but I did see some circular mirrors at this art store. I'll check their diameter this weekend. But I have yet to actually make an LED saber, And I doubt I would be able to remove or replace the tip, I'll prolly screw up the blade. But I'll worry about that later...
