Interesting upgrade. Nitecore changed the spread of the light range at the lower end, changed 65/135/300 to 1/40/120. I think I like it better this way. I was reading through the Users Guide to see how the various levels were switched and noticed something interesting. As far as I can tell, they have changed the Voltage display to Power Level display, which is just a series of flashes showing relative power levels. Geek that I am, I think I would rather have the voltage display.
If I didn't already have an EA4W, I would be very interested in this version.
