I wrote this up for another site that I moderate, but it fits here too. Remember review is strictly the experience and opinion of the reviewer and your mileage may vary accordingly. The Inova X1 is a single cell personal pocket flashlight which uses AA Alkaline or Lithium batteries. Price is normally around $20, can be picked up on Ebay sometimes cheaper, or they are carried in stock at Target chain stores. The light is 4” x 11/16” which is an inch shorter in length than the 2 AAA version Minimag, and the exact same size as it at the bezel. I will use the Minimag lights as comparison flashlights because almost everyone either has one, or has used one and they are the most likely encountered personal carry flashlights currently. The light is activated by twisting the butt cap of the light, or pressing on the rubber capped butt for momentary usage. The light has an aluminum body with stainless steel bezel. The body is coated with hard anodize III in either black or silver. This is the second incarnation of the smallest Inova light in their X series of flashlights. The new version is a flood type beam which most will recognize as the typical flashlight light pattern. This has been changed from the previous versions “spotlight” beam with the TIROS lens system which provided no side spill at all. This is currently the only version sold by Inova, sometimes you will find older versions sold by vendors that have not worked out their stock yet. The new version lights come with a lanyard, a few of the first new versions came with the old versions sheath but they are fast disappearing and the lanyard will be the only option. I drop tested it from 5 feet onto my wood deck half a dozen times and then dropped it in a pail of water and it was not effected by either test what so ever. Specifications: (some technical specs beyond my ability borrowed from Flashlight reviews.com I will use their output and throw specifications for review against other lights on their site which I highly recommend one peruse before buying any flashlight ) Length: 4 “ Light Source: 5MM LED Battery: 1 AA Alkaline or Lithium Diameter: 11/16” Output: 600 Throw: 60 Battery Life: 8 hours to 50%, Approx. 15 hours to dead (my test) Weight with battery : Unknown but slight heavier than a AAA Minimag with batteries lighter than AA version Minimag AA and AAA version Comparisons: AAA Length: AAA 5 “ Battery: 2 AAA Alkaline Light Source: Minimag Bulb Diameter: AAA 11/16 bezel 7/16 tail cap Output: 200 Throw: 465 Battery Life: 40 Min. to 50% , 2 hours to dead AA Length: 5.75 “ Light Source: Minimag Bulb Battery: 2 AA Alkaline or Lithium Diameter: 15/16” at bezel 11/16” at tail cap Output: 580 Throw: 884 Battery Life: 40 minutes to 50%, 5 hours to dead Pluses: Decent brightness, water resistant, rugged, long battery life, uses common AA battery. Minuses: I liked the first versions sheath much better than the cheap lanyard included in the second version. There have been a few reports of flickering due to excess anodizing around the bottom rim of the butt cap or inside the body above the threads where it makes contact causing loss of contact. Simple fix by sanding it off. There have been a few reports of the first lights in this version losing the outer lens, but I have not heard as much of this lately so this might be fixed. I have not encountered either in the newer versions I have. I did sand the bottom rim of the buttcap and the body on one older version and it took care of the flicker. Conclusions: The Inova is a very well built flashlight. It is a very good pocket light for most close range uses needed in a pocket light. It provides excellent close range light actually brighter than either the AA or AAA minimag. Battery life for the one battery is twice as long, than either the 2 AA or 2 AAA version Minimag lights, which are a bit over long for a pocket carry light. Hard anodize III makes it a very durable look that will last. Throw is not comparable with the Minimags which is to be completely expected, especially given the long battery life. I like it so much it is my current EDC pocket light that I carry with me everywhere. Flashlightreviews reports that reknowned world traveler Doug Dyment of Onebag.com recommends the X1 as the flashlight of choice for world travelers which is a pretty good testament to it.
