With more horsepower than the Helion, the Vectra IQ emits brilliant light, when using either the LEDs or Xenon bulb. Four SuperBright LEDs above a Xenon bulb provide excellent lighting regardless of the activity. Intelligence has been integrated into its circuitry making its power output more efficient. Constant illumination, a battery-power meter and "mode memory" all help increase illumination and efficience. A redesigned battery box with a rubber back provides comfort while housing four AA batteries. The Vectra IQ is a powerful and highly function headlamp for any nighttime activity. Spare Bright Xenon Bulb included.
