Description
The LED Lenser LL7459 is a current interpretation of the classic incandescent flashlights of the past years. Though it somewhat resembles and represents a generic flashlight shape, it uses an LED instead of an incandescent bulb and it employs a computer designed collimating optic rather than a reflector. Most conspicuous is the use of billet or bar stock Stainless Steel for a manufacturing material. This puts the LED Lenser LL7459 into two categories. It's both functional and decorative with decorativeness being more heavily weighed since in fact it has the heft one would associate with a paperweight or sculpural art object, rather than with a lightweight flashlight.

Evaluation Results & Summaries

Ease of Use
Excellent. The user simply locates and depresses the steel click On/Off switch button to turn the light On and Off. Focus is fixed by the collimating optic to a spot with a square shaped corona. Battery replacement simply entails unscrewing the tail piece in exactly the same manner as if one were replacing batteries on a standard CR2 light. Charging simply entails the removal of a protective rubber plug from the charging connector socket and the insertion of the cable connector. An indicator light signals that charging is taking place.The color of the indicator light provides status information. Red= Charging, Green = 50%-90% Charged and Orange = 100% Charged. 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 or it may be carried in the included dedicated belt holster designed specifically for that purpose. This holster provides some environmental protection while at the same time it permits the operator to use the light without having to remove it.

Task performance optimization
Fair. The LED Lenser LL7459 is primarily a decorative gift item that happens to be an excellent flashlight using cutting edge technology for both a source of illumination as well as. Due to its mass and weight it's not as practical to carry as other lights in this category. In addition- though effective, the photon management system of using a collimator, provides illumination that though useful at medium ranges; falls short of other lights that may have even less powerful emitters. As such it may be described as an exquisite compromise between aesthetic elegance and practicality

Battery Charging (Ease, Frequency, Maintenance)
Excellent. Even without a manual the user will manage to divine the necessary procedure for charging with no effort at all. The changing color of the charging status light requires only one time vigilance in order to know that it changes over the course of the charging duration. The NiMH battery holds as much energy as that of another light of the same form factor and conforms to the characteristics associated with NiMH battery chemistry. In other words, it looses some energy passively but because it does not exhibit 'memory' it may be topped off and doesn't require a discharge to alleviate memory issues.

Balance, Grip-ability, Stow-ability, Tabletop Stand-ability
Fair. The LED Lenser LL7459 surface finish is the satin like sheen one associates with brushed, stainless steel. While this provides an acceptable grip surface for a bare handed operator under dry conditions; it's less than optimal for contexts that may involve moisture, oiliness or grease. This is especially true given the mass of the LED Lenser LL7459. It does live happily on a desk top or as a part of interior furniture and thanks to a flat tailpiece; makes a fabulous ceiling bounce illuminator

Items of Note:
The LED Lenser LL7459 is the sort of product one gives to someone to commemorate a special occasion. It equally makes a fine example in any collection of technology products, modern or machine age art or unique flashlights. There are few examples of flashlights this large made from solid stainless steel bar stock, and the LED Lenser LL7459 may even be unique in this respect.
