I am just finishing up my Pinbot and have replaced all the lamps with LEDs. These are the ones I used in my 5x5 matrix. I used color matching LEDs and they look amazing! Not too bright, but then again I tend to think that it can never be TOO bright!
I have no issues with ghosting or any other problems. I really like these Ablaze LED's. Out of several hundred, I have only ever gotten one bad one. Not worth the trouble for 89 cents to send it back.
Hope this helps.
