I own two: an OMS 21W HID, and a DiveRite 10W HID (slimline canister).
The OMS throws a spectacular amount of light, but the canister is big (I have
to attach it to my backplate) and the light head is quite large. I use it only for some
night dives and some lava tube / "cavern" dives. The head is focusable.
The DiveRite 10W is the light I use all the time -- the canister is small and fits
on the waist strap of my harness, and the light head is small and convenient.
For me it's a perfect light for cruising the reef and looking in pukas (holes)
for interesting critters. The head has a fixed 6 degree beam. I am absolutely
tickled with this light.
FWIW I also have a light cannon; I usually loan it to visiting divers.
Also FWIW my regular buddies dive with a Halcyon 18W HID and a NiteRider
halogen.
