Why are Diamond Dragons not used more commonly?

[easilyled]

Just wondered why Osram Diamond Dragons aren't used in flashlights more. (Not golden Dragons which are more common)

From what I understand, they output almost as much as quad-dies like
the SSC-P7 or Cree MCE, but because they are single die leds,
they throw much better and don't have donuts or crosses in the center of the beam.

Therefore I would have thought that they would be the ideal led of choice.

Certainly if you look at the beamshots in this thread (post #8), they look very impressive:-

I'd be interested to hear any more more about these relatively unknown emitters.

... was not able to find Voltage ratings ... :thinking:
(thus assuming single-die emitters)

but with 225 lm @ 1.4 A they seem to need almost the double power than SSC/Cree
(somehow resembling the older K2s, as the nominal drive current is so high)

(PS: how come You mean they produce the same light than full powered quads? is there any documentation?)

I found this link which shows 330-390 lumens output at 1.4A for the group binned as NY (see page 8)

This matches the figures given in this Sales Thread on B/S/T

This output certainly seems to be in quad-die territory as far as output is concerned.
For instance MCE K-bin outputs a minimum of 370 lumens at 350ma per die which equates to 1.4A in total

Probably the NY bin is available only in a limited quantity? The lower bins don't look so interesting.

Well the NY bin looks like a flashaholics's dream.
