/ubbthreads/images/graemlins/smile.gif Even though we lowered the published spec, we still use the B1S and B2S LEDs as before. I just wanted to have something to fall back on in case we couldn't get the best LEDs. Fortunately, we have always been able to use the LED we originally specified.
Over time, the Arc-AAA has progressively gotten brighter due to slight improvements in LED quality.
