Images of one of my newly acquirred 8000 mcd blue LEDs (got 100 of them).
They will make a nice cluster once I got all the needed parts (going to post images once it is done).
Also got instant headache from looking directly into the light.


Now post your LED pictures!

Walrus | Why would you buy a hundred of those things in the first place? I would join in but i have no LEDs and no plans to buy any

They will make a nice flashlight.
SickOptometrist, you can see a laser warning sign in the top left of the first image if you look close enough (got it for my HeNe laser back then).

That's what the cluster will about look like (this has no functionality as the LEDs are just sticked onto the PCB).
Didn't decide yet if I will control them multiplexed (loop through all rows and set the row either on or off depending on what the flag in the driver µC is set to) or 13 latches (13*8 = 104, 100 LEDs) with transistors, while option 1 is easier to use (less soldering work). Option 2 however, has the better performance.

Bump.
Update:
Finally got around to make the LED backlight for the LCD I got 2 years ago off ebay.
5 white <can't remember value> mcd LEDs:
