3 x N-Cell drive 1 5mm LED, either white or blue, uses an aspheric lens for a moon-like beam, just the Inova X1.
Brass construction with silver powder coat finish, rubber push-button switch for momentary or constant-on, seems a little weak, there's a spare rubber cap in the tailcap.
You can change the LED on this one easily.
Although ... seriously ... I cannot recommend this one ... too dim ... too big to carry ... there are better alternatives.
