It was asked, but it wasn't asked here specifically.

May the Bin 1 cyan RIP with its noble sacrifice for a good cause long remembered.

Yes virginia there is a heatsink in well made sabers, with good reason for proper heatsinking now proven.

I know.  But hopefully it's untimely death will help others avoid the senseless destructions of other LEDs.

PJ - the question was asked recently at TCSS and then again yesterday on another venue.

It was sacrificed for the greater good. We can observe a moment of silence for it if it'll make everyone feel better.

HAHAHAHAHHAHAHAHA, that tickled me funnybone mate!

There was a querry posed questioning the need for a heatsink, or what is or is not acceptable forms of adhesion and heat dissipation.  This should clear any questions up for everyone now and to come.

Such a pretty led....great sacrifice!

Well, if you're going to make a martyr out of an LED, make it one people will actually cry over.

Even a little Lux III is / was an important LED (way back when). Just because it's old and elderly now - it probably still works well in a little stunt somewhere.  :D

I have to echo the sentiments of others, I'll mourn that poor bin 1 cyan  :'(

Good demo though. This should be stickied at TCSS

I guess this thread is a jab at some noob who posted over at TCSS on how he doesn't want to spend money on a heatsink cause it's expensive and it is something unnecessary.  :D
