Quickbeam, you must be a very kind and gentle person! Four stars for this light is very generous. I've used a BD Gemini for a long time and was very happy with it. When I got my Vectra IQ last december, I was extremely disappointed. The beam is terrible! All the old models had such a nice smooth beam and now they are selling us these? The package says "Focused, artifact-free light with new Ultem reflector". This must be a joke for insiders, cause you won't find many lights with poorer beams! Another disappointment: the "intelligent circuitry for constant illumination" is not regulation (as one would expect). This light gets dimmer and dimmer until it's out. Looks like the brightness levels are just different resistors (a runtime plot would be interesting). Now the battery indicator: it's worthless, because it changes almost randomly. It might show "red" just 30 minutes on new batteries, then after being turned of for just a second it's back on "green" for another hour! This light is seriously troubled and way too expensive for what you get.
