Continuing the comparison, at 18':
Halcyon HID 21, LM LED 21, DRIS 1K Shorty, DRIS 500, Intova Ultra Nova, SSC P7 "900"
Halcyon HID 21 and LM LED 21, for perspective
LM LED 21 and DRIS 1K Shorty

All the lights at a wall ~130' away
Here, the comparison stops, because I could not make them meaningful within the spillage of each other, so . . .

So, for my $.02, which is more than it is worth:
I like the Intova Ultra Nova for clear, warm water open water diving, because the spot is bright enough and small enough to play it on your buddy's arm/hand and get his or her attention. It can be reduced to 30% for night diving, and the strobe feature is good for emergencies.
I definitely like the DRIS 1k Shorty for a backup light for caves, because it's almost as bright as the primaries, and will get you out quite easily in case of a primary failure. It'll fit a WHOLE lot better on my harness, too.
