Ok, I found my Expedition 1400 and compared the two.
In terms of total emitted light (the now-famous "bathroom ceiling test"), they're very, very close. In terms of which flashlight has a brighter beam, that goes to the Expedition Star.
In terms of which one "throws" farther, that honour goes to the Expedition Star. It has a tighter, brighter hotspot than the 1400 has (this is also why it looks so much more brighter in the picture), so it can project its beam farther than the 1400 can. It's not an issue of one being "better" than the other; it's the LS LED and optics in the Expedition Star, versus the Nichia LEDs and no optics in the Expedition 1400.
On the left is the Expedition Star, on the right is the Expedition 1400.
Both were shot at a wall about 5 feet away for this picture.
I live in the middle of a city and don't have ready access to woods, so please don't ask for non-wall beamshots.
