Gentlemen:

     I am not an electronics man, however I have been using  LED's in our AOA systems for 14 years.  Use caution and be aware just  because the LED's come from the same supplier, they may NOT have the same  intensity.  They also have different dimming requirements for  different colors.  We have found that if using the Ultra-Bright LED's they  must be individually paired (same colors and different) to insure they all dim  the same.  Not a big deal, but if you are looking for professional results  best to take the extra time and compare them prior to soldering and saying  darn I should have  All except the Ultra bright by the same mfg. seem  pretty good, but a large variance even in same order of 50 LED's ordered at same  time.

    I've heard this before. A number of folks who supply

    sunlight viewable dead-front annunciators have mentioned

    a need for matching sets of leds for output to achieve

    uniform appearance across the panel.
