In a word, Fantastic. The LEDs are indeed super-bright and for general use, the LEDs are sufficient to light your way. I have a Soliras as well and compared to that, the difference in the LEDs are amazing - well 2 vs 4 so go figure. The reflector does an excellent job of optimizing the light and the "Find Me" light is an added bonus. I normally don't use the main xenon light but that is really bright as well. Better value for money than the Soliras I believe but with that light, you are basically buying the rechargeable battery with a brighter beam.
Would definitely recommend the Vectra IQ to anyone wanting a bright light and excellent proximity lighting. If you need a further reaching light and a rechargeable battery, go with the Soliras. I couldn't decide which so I bought both.
