Extremely bright safety/town light a longer charge cable would be good though
Moon Mask 5 LED Front Light
8 10

Form definitely meets function with the Moon Mask 5.0 LED, which claims to delivers a whopping 70 lumens in the highest of five modes-just enough for tackling well surfaced lanes at 20 odd mph and a real boon for roadside repair, pannier rummaging and map reading. It certainly gave a punch performance in our beam test and the stats seem to bear that out too.

A red pulsing light indicates low battery giving the option of charging home in twenty minutes, or toggling to economy settings as conditions dictate. Fully charged in two hours, it shouldn't attract unwanted attention from the office snitch and forgetful folks can sleep soundly in the knowledge intelligent charging prevents the 3.7 volt lithium polymer battery from being boiled within an inch of it's five year life expectancy...

However, it's a little thirsty in the higher settings beyond point-to-point commutes/training runs. Essentially the Moon Mask takes the alternative approach to run time over output than something like the similarly priced Cateye Jido which runs for much longer but also puts out less light. Either approach works, it simply depends on which works best for the type of riding you do. The Moon Mask's potential drawback is that if you are running it at it's brightest setting most of the time you need to remember to keep it charged up, and while the short charge cable is cosy beside the laptop or tablet, plugging into the desktop tower could leave it vulnerable to careless size nines.

Measuring a diminutive 6x3 by 5x1 the Mask earns its moniker from the option of aftermarket top caps for the last word in personalisation. I understand the appeal but will pass at £12 a pop. More impressive are the five Nichia LEDs developed for optimum front and peripheral illumination, which project a razor sharp beam of light that seems particularly potent when performing tricky right turns. Driver acknowledgement is to a grin inducing 550 metres, dropping to around 350 through congested town centre rush hour traffic.

Thanks to the clever rubberised strap mount that seems a genuinely universal fit to 30.8 bulge diameters although it struggled a bit on some oversize bars, it can also be persuaded atop a helmet. Choosing this option seemed to increase its efficiency-encouraging myopic drivers to dip their lights sooner while discouraging some of that all too familiar casual indifference shown by larger vehicles when crossing staggered junctions.

Switching between modes, is easy wearing full-weight winter gloves and on the fly. Run times seem broadly faithful to the blurb, unaffected by plummeting temperatures and delivering a consistent 2 hours 47mins, 5 hours 50 and 8 hours 24 (mins) in high, strobe and flashing respectively.

road.cc test report

Make and model: Moon Mask LED Front Light

Size tested: Black/Silver

Tell us what the light is for, and who it's aimed at. What do the manufacturers say about it? How does that compare to your own feelings about it?

Moon give little away as to the Mask's target market but testing suggests it's a very powerful secondary safety lamp that transcends genres (save for touring without a portable charging interface). Bang on for desk bound commuting, it consumes nominal space so equally welcome for summer's swan song and those afternoon training runs that overlap into dusk.

Tell us some more about the technical aspects of the light?

Good but struggles a bit on oversized drops.

Rate the light for waterproofing. How did it stand up to the elements?

Generally fine, although USB types are more vulnerable to extreme conditions simply by virtue of the charge interface. That said, water resistance is very good-just check jacket pockets before slipping them in the wash.

Tell us how the light performed overall when used for its designed purpose

The Mask is a remarkably bright safety light that trounces a lot of traditional town lamps in terms of output and makes a perfect complement to minimalist cockpits. However, at £12 a time the interchangable top-caps seem a bit gimmicky and a longer charge cable would've been welcomed.

Tell us what you particularly liked about the light

Good looks, commendable output and convenient charge times.

Nothing but a longer USB charge cable please.

With the USB charging lead, is the lamp end connection a standard mini USB connector (like Garmin), or is it a plug specific to this lamp?


Comrade [220 posts] 6 years ago


I got one of these lights last week and it is great, and it is nice and small but gives good light. The charge cable is relatively short at around 50cm (but fine) and looks like a regular USB connection. It has a small connection at the other end the same as my digital camera and MP3 player but the instructions tell you only to use the supplied charge cable.

Standard USB-mini connector, after a year of casual city and provincial evening use - they turn the street lights off from 2am in this part of the world... - I'll be replacing it with the very same model.

I've had no problem using any USB mini cable, be that the provided 'power-only' cable or run of the mill 'power + data' cables used with other USB accessories.

I've just got of these lights, mine is branded 'areo' but it's still called a 'Mask'. I got it from PlanetX.

It will only charge from the supplied USB cable, I've tried loads of others and it's really fussy, no others will work! This is a pain as I planned to not have to carry the cable with me to work, it's inevitable that I'm going to have to charge it sometime when I don't have the cable.

An annoying feature. The including instructions go as far as to say the unit can be damaged by not using the supplied cable.

I've no idea what is so special about the cable, perhaps some of the wires are cut or something.

Anyway, it's a tiny light and goes neatly onto either helmet or bars, in all other respects I'm pretty pleased. But this may as well have a proprietary connector! (I never buy stuff if I can help it that has non standard connectors).

I've had one of these for 18 months and its brilliant. Really tiny, really bright and enough to ride dark country lanes with for short distances - even lit some pitch black Norwegian tunnels brilliantly on the Bergen Voss. Easy USB charging (no cable challenges for me - used loads of different ones). I use it on flashing mode for all my winter training rides along with my Exposure Flare.

Absolutely excellent and recommended.
