Hmm, this works out at approximately £23.56 a diode.
Anyone interested? I estimate the postage via airmail to be around £1.20 which isn't bad at all.
I might be able to negotiate and get a phlatlight or two
Also is 6 650nm line generators. at approx £2.92 each. Brass could have copper fins plated onto it which might be ideal for cooling low power diodes.
One idea I just came up with is mounting the diode, heatsink and optics onto the top of a used PSU fan.
As it spins the output line would cover a filled circle whose diameter increases with distance. Just the thing for laser video projectors, and with a fisheye lens you could use it as a sphere projector aka "Eye of Sauron"
Power it with wireless induction using the existing field coils on the motor itself. Simplez.

Niffty thought except total cost is ~$430 US, and you only get 10 diodes, so that works out to ~$43 US each, with no mounting hardware, you don't if these are actually 445nm, and you still have to include distribution shipping.
However a recomended alternative could be.... , and the diodes are in fact 445nm and 1-2W range, trust me I have one and it outputs 1.232W.

A bit of a tip for your GB.
Buy the crapio XJ-A140 projector (A-140s only!) each one houses 24 diodes (And a world of optics, powerfull LED, and other fun stuff for your entratainment) , and these projectors can be had for 750-800$ shipped in US/can depends where you look at.
Thats 30$-35$ US a diode. IDK what the postage to our europe friends is, but it can't be too bad considering that these diode wieght fuck all. So it can be sent in a small envalope or something.
As for the diode outputs, there are currently two models for then IIRC, from the projector seires, of A-130(discontiued), A140 and A-150
A-130s are of lower wavelenth then 445nm(not by much) and will handle less power, and A-140/150 are the same diode as in that thread, but will do up to 1.5W of power (you can push 2W, but I don't like to just to keep the life time healthy).

445nm laser group buy?
