its nowhere near new, but it will be fine for checking out disturbances at night outside the house. i highly doubt it cam illuminate distances beyond, say, 200 feet?
since it new, i think its a good idea to get some sort of screen protector for the "window"., IIRC its not scratch resistant glass. the runtime is a rather short 2 hours, so this is not your ideal blackout light. never seen the beam profile before, but if there are artifacts in the beam, some LDT (light defusing tape) should smoothen the beam.
lastly, if its kept always charged do check periodically for battery leakage.
