Looks like the LED6 has a few more features. I do like the Dot Matrix display better than the segmented LED display. Easier to read on a scrolling message.
IIRC, The LED-6 & 7 are not interchangeable. The 6 is made to replace a shelf mounted TimeMaster and the 7 is bolted on by the flanges. They are physically different in size and shape.
