OK...I've taken a look at the various models mentioned....here are my observations...

The River Rock lantern from Target is a different lantern than those from the Christmas three-pack (3 lanterns for $20) that I mentioned. Those from the three pack are nearly identical to:

Osram Golden Dragon lantern
Brookstone lantern
Brunton Glorb LED Lantern

Besides a slight difference at the bottom of the base, these from the holiday Target 3-pack seem to only have on and off rather than the strobe/low/high features mentioned by folks for the others. Also, the use-sheet that came with them says there is a low and high mode but none of mine had the low mode...just on and off.

However, as noted above, John says that the LEDs in the Osram version are different...I can't comment on this. Outwardly, they're the same. Does anyone own all of these models?
