I must admit I wasn’t expecting much from this light when I received a model for review. It’s pretty tiny and I was anticipating a correspondingly small light output from the diminutive package. I was wrong – It’s a great little rechargeable light capable of an insane light output, has a decent mounting bracket and great build quality and weather sealing.

Package Contents

You don’t get much in the package but you get what you need – the light itself, a USB charging lead, a rubber seat post mount and an instruction leaflet. If you don’t have a USB socket in a convenient place for charging, you’ll need to buy a mains adaptor.

Build Quality

A number of the latest lights on the market today have pretty rubbish build quality suffering in particular from either poor mounting brackets or poor weather sealing or both. I’m happy to say this isn’t the case with the Moon Shield 60 and it has a pretty solid feel and is better sealed than most rear lights I’ve seen in a while. The weakest point is the rubber USB charge socket cover which is attached by a very thin strand of rubber. I don’t think it would break in normal use but you do need to be a little careful when removing the USB cable. The mounting bracket is made of a stretchy rubber which can fit round pretty much any shape or size of seat post.  This can be fitted with no tools.  Embedded into the mounting bracket is a simple plastic slot into which the light itself is mounted. Once attached, the light’s vertical tilt can be adjusted.

On top of the light is a well sealed rubber push button that definitely wont get accidentally pressed when the light is carried in a pocket or bag. Consequently it can be a little tricky to operate with gloves but it can be done.

Battery Life and Light output

When I turned the light on by a press of the button, I was pleasantly surprised to find the light was just as bright as the Blackburn Mars 4.0 and the Cateye TL-LD1100 that feature on my best bike lights list. Then I realised that was merely the minimum light setting. Pressing the button again raised the light output to a level exceeding that of pretty much all rear lights I’ve ever seen. There was worse to come. A further press of the button caused yet another step up in intensity to a frankly bonkers level. Unless you ride regularly in thick fog, the brightest setting is way more intense than necessary and I imagine most people will use the light on one of the lower settings with longer run times between charges. In addition to the constant light output modes there are two flashing modes, the first has a rather unpleasant strobe effect, the second a more bearable slower flashing. These can be seen in the video below.

While there are not separate side LEDs the central LED generates a wide enough beam to give very good visibility from the sides as well as the rear.

Specified battery life is 5 hours 40 mins on the lowest setting, 3 hours 50 mins on the medium setting, 2 hours 30 mins on the highest setting and 7 hours on the flashing modes. My tests showed these to be accurate to within a few minutes. Considering the size, weight and brightness it’s actually pretty decent and will be plenty for most commuters. In all modes the light output maintains its same bright level throughout the run time but then cuts out suddenly. There is a low battery warning light but it is not much use. One, it can hardly be seen right next to the bright main LED and two there is just not enough warning from when the warning  shows to when the light cuts out. (15 minutes if you’re lucky). Really with this light you’ll just need to be organised and remember to recharge it on a regular basis.

Charge time for the light is approx 2 hours. There is a charging indicator LED that shows when charging is complete, and unlike the low battery warning light, it is useful.

Compared to Cateye TL-LD1100

In an attempt to make the rear light beam shots more useful, I’ll now be showing the beam alongside our benchmark rear light, the Cateye TL-LD1100. Here we have two photos showing the output from the two lights side by side. In the first, the Moon light is set to its lowest brightness setting, in the second it’s at the highest setting. In both, the cateye light is set at its maximum constant light output. As can be seen the Moon light (on the left)  is both brighter and has a considerably wider beam pattern than the Cateye on the right.

Conclusion

All in all I really like the Moon Shield 60 light. Apart from the daft low battery warning light I can’t find anything bad to say about it. Highly recommended and an easy choice for our best bike lights page.

The light is fairly widely available. For example it can be purchased  here or here.
