Rating: 2 / 5
a beloved friend whose time has passed.
A nice little task/proximity light in its day. So light in weight. Produced enough light for its intended purpose.
However, it has been passed by other small Li coin cell powered microlights sporting 1 (Photon), 2 (PT Scout), or 3 (Petzl e+LITE) 5mm LEDs.
It's still useful and i'm not throwing mine away or palming it off on some neighborhood kid. However, it's just no longer at the head of its class.
Based upon its current competitors, I'd give it a 3 rating for its weight and light output, and ergonomics, EXCEPT for the form factor of its chosen power source. That little 6VDC PX28A/PX28AB (aka 4LR44, IIRC) battery is NOT the most convenient power source, nor does it, for its size, contain highly dense stored energy. A least now it's available in an Alkaline battery chemistry vs. its original mercury based chemistry. Still, even in an alkaline chemistry it only has 110 mAh of stored energy (a single good quality CR2016 batt has ~90mAh of "useful" stored energy, and a CR2032 has ~225mAh).
Taking this power source factor into account lowers my Rating to a 2.
