Description
The Vortex Vision XR1 is direct rechargeable alternative to the venerable MAG Inc. Mini MAG-Lite. It uses a bi-pin Xenon lamp that produces a beam comparable in profile, color and output to that generated my the Mini-MAG. Unlike the stock Mini-MAG however, the XR1 is a rechargeable that in many ways mirrors the features and functionality of the larger lights from Vortex Vision. Charging of the replaceable battery occurs through a connection with either an AC adapter or a 12V DC Automobile adapter. This is essentially an eco friendly glove box flashlight that will be of interest to journeymen everywhere that have grown weary of disposable batteries or of the added inconvenience of purchasing, maintaining and charging NiMH cells separately. In addition to being table top standable for ceiling bounce mode, the XR1 has a pushbutton switch that allows for a separation between focus and activation.

Evaluation Results & Summaries

Ease of Use
Very Good. The user simply locates and depresses the click On/Off switch button to turn the light On and Off. . Rotating the helical screw head allows for adjustment of beam angle from a spot to a wide-angled beam. Battery replacement simply entails unscrewing the tail piece in exactly the same manner as if one were replacing batteries on a standard MAG-lite. Charging simply entails a firm push of the charger connection plug into the corresponding socket in the light. A Red indicator light signals that charging is taking place. Because the tail-piece is flat, the light may be stood upright for a ceiling bounce style of illumination indoors. In most cases, the light may be stowed head down on a flat surface . In addition, subtle longitudinal grooves cut into the head somewhat mitigate against a run away light rolling along a smooth surface when laid down horizontally.

Task performance optimization
Fair. The XR1 provides a practical source of close-range hand-held illumination for contexts that demand a combination type beam that is useful for close range navigation as well as inspection and searching. This light is not intended to compete with it's larger siblings or with more powerful LED and Incandescent pocket lights.

Documentation Quality
Satisfactory. The instruction booklet is Quadri-lingual for English, Spanish, French and German reading customers. It's written and illustrated in precise, concise and professionally laid out step-by-step sections that enhance optimal information absorption and that minimize mistakes. Typographic font size is much smaller than average size , making it difficult for persons with poor eyesight to read.

Battery Charging (Ease, Frequency, Maintenance)
Excellent. Based on a procedure described in the instructions, the charging set-up and procedure are easy. Frequency of charging will depend on the user but since the manufacturer recommends charging after each use, the customer doesn't have to monitor re-charge cycles too closely. A caution is made to not over discharge the battery (running it down flat) and to remove the unit from the charging cradle if it hasn't been used in a month. In the past, NiCad batteries required a strict maintenance procedure that involved running the battery down and recharging them fully to circumvent the 'memory' effect. The current crop of NiCad batteries don't require this step. Like most rechargeable batteries however, the XR1's NiCad's do benefit from a few initial charge/discharge cycles in order to 'break them in' for optimized capacity. Careful positioning of the light onto the cradle is required for a solid contact to occur. This is a common feature of all the Vortex rechargeables

Balance, Grip-ability, Stow-ability, Tabletop Stand-ability
Good. The XR1 performs in a practical manner to be immediately available to its user whether it's placed head up or tail up on a table, head up in a belt carrier or otherwise stowed in luggage. Somehow the build quality of the battery tube or 'body' seems somewhat delicate as compared to comparable lights in this size class. Its build is satisfactory for users that will not abuse the light but falls short of being as rugged as its forebears.
