The Moon Comet front light resembles an office strip light that's been passed through a matter-shrinking device. The result is an extremely powerful and surprisingly tuneable light source capable of 110 lumens in overdrive setting.
Most conventional designs work on the basis of a single diode fitted to single printed circuit board, but the Comet employs COB (chips on board) technology whereby a series of tiny diodes proliferate the same space. On paper at least, these enjoy a lifespan of 25,000 hours whereas the rechargeable lithium polymer batteries are good for five hundred cycles before retirement.
Getting started demands a couple of hours charging via a USB port. Run time is excellent; we've managed one hour twenty seven, two hours thirty three, six hours thirteen respectively in overdrive, high, standard, 50/100% flash and strobe settings. The low battery indicator gives plenty of notice when it's giving out.
The watch-strap style mounting system works well and seems dependable.
Weatherproofing is always something of a compromise but we've had no problems in spite of deliberately leaving the port plug open and riding sans mudguards for several hours along waterlogged roads.
A recessed, rubberised switch is in keeping with the Comet's sleek profile but a little hit n' miss in full-finger gloves, especially on the fly, which is a consideration for winter.
Straddling the gap between see-by and seen-with, it's been possible to navigate unlit sections to around 18 mph thanks to a lovely pure beam in 'overdrive' mode. Drivers acknowledged my approach from approximately six hundred metres, less around town.
Dipping down to 'high' from 'overdrive' conserves power and seems optimal for segregated cycle paths to fourteen mph, pricking driver and pedestrian consciousness from 500 metres, although strobe and 100/50% flashing options catch the eye more easily.
Swapping from steady to flashing means depressing the switch for a few seconds, whereupon single prods select the most appropriate speed.
My only criticism of the Comet is that I'd like a little more side visibility to help at junctions and roundabouts.
Fairly powerful commuter light but side visibility could be better.

Tell us how the light performed overall when used for its designed purpose
Moon Comet's specialist technology produces one of the purest beams I've encountered to date. Rubberised switches feel a little odd, yet are easy to use and it's obtrusively charged from USB ports without attracting attention from the office snitch.
Great for desk bound commuters and/or winter training, 100 lumens is adequate for suburban navigation but shared and flashing are equally conspicuous to oncoming traffic. However, peripheral presence needs improvement and the battery indicator is less informative than others in its class.
