Conclusion: The Streamlight Septor is a pretty slick headlamp. It is basically an "all LED" version of the Streamlight Trident . Having the ability to adjust the LED output very rapidly just by clicking on the switch equates this to a 7 LED headlamp with a dimmer. A VERY handy thing to have. Need just a little light - one click, need more - 2 clicks, need a lot - 3 clicks, want less again - click 2 or 3 more times. Pretty easy and straightforward, just the way a light should be.
