@colleen - thanks for the screen-shots.

in your other video, is that a teletype or dot-matrix printer in the background?

5500 OTF lumens ?!?!? that's more light than a truck! do you ride in caves? on my sub/urban rides, 20% of that would be more than i'd need.

as for CMOS not responding to LED light, i haven't heard that before. it may depend a lot on the color temperature of the light... so the (cheaper) bluish-white LEDs may not show up as well as more white LEDs.
