UTD lights

[trek]

Does anyone have hands-on experience with the new VIZ35/50 hand-held lights that UTD sells? They are rated at 3500lm (single LED VIZ35) and 5000lm (3 LED VIZ50 ), run on 3x18650 (or canister battery with an adapter) and come with a hard Goodman handle, priced at ~500$. Looks like a lot of light in a small package. Any thoughts?
