For all your zoomies with q3, custom projects or to play with tir optics which can be found cheap, various collimating degrees that usually snaps perfectly onto XR-E emitters (tedious with XP-E).
Good old XR-E. Might be old but it's still a very nice emitter for throwy lights. :)
Wow, after clicking that link I was logged into your account (at least I think it was yours) 
First I didn't notice anything wrong but after going to shopping cart delivery address was to Slovenia and I couldn't change it. Then I noticed it was logged in and I could see "My account" and stuff, so I logged out.
Now I can click that link and it doesn't show your account. Weird.

LOL, serves me well not logging out before pasting the link. I should have known better.
Anyway i ordered 7. :) I have some ideas what to do with them.
Q2 were not appealing much for the price difference vs q5.
I got the osram warm whites a while ago (15 pcs) and ordered a few snap in tir optis especially made for osrams at 0.8usd to try them out.
I also made a few P60 dropins with osrams smo reflectors and amc 1A drivers single mode. (lovely althrough not so bright as an q5)
