Moon Shield rear light



Very bright rear light for year-round all conditions use, though the Strobe mode could be annoying

At every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

What the scores mean

Good scores are more common than bad, because fortunately good products are more common than bad.

The Moon Shield 60 is one of the current breed of high powered rear lights that comes with a range of modes that range from visible to bright to downright antisocial. It's guaranteed to get you noticed though.

The '60' part of the name comes from the lumens the Shield is claimed to put out at its highest output, the Over Drive setting. It's bright, probably too bright to have it pointing straight back at following drivers, so Moon have included an adjustable bracket that allows you to angle it slightly at the road surface. Not only is it bright enough then to still provide plenty of visibility you also bathe the ground in a red glow which makes you look bigger on the road than you actually are, reducing the number of close passes.

That's a bit of driver behaviour modification I first noticed using the mega powered Hope District (110 lumen) last winter and it works with the Moon too.

At its heart is a single CREE XP-E red LED paired with a 3.7V 700mAh lithium polymer battery which will give you around a 2.5 hour burn time on that Over Drive mode. That's not quite as good as the Exposure TraceR which has the same capacity battery but runs for 3 hours at 75 lumen, but it's impressive nonetheless. A battery indicator lets you know how much juice you've got left.

You get a Standard and High mode too (output/burn times are below) before you reach the two flashing modes, a straight forward Flashing and the Strobe setting. This is the antisocial one. You'll stand out but just looking at it gave me a headache within seconds so it's probably a bit unfair to inflict on others.

The majority of the light is put out as a spot with an angle of 33° according to Moon's website with it fading off to a 58° beam angle. The red and clear lens does allow for full 180° visibility allowing you to be seen from the side, important for junctions.

The bracket's not the most sturdy of things and while I haven't had any issues it does allow quite a bit of bounce with the light in situ. It's not a major concern being at the rear but it's something we'll keep an eye on over the long term. You can get a saddle rail mount as an optional extra which would be useful if you have an aero seatpost.

The ability to deal with the wet is a big thing with rear lights. Having it conk out without you realising while on a damp night ride isn't ideal. The Shield passes both road and bathroom shower testing with ease providing the rubber USB cover is tightly closed, if any rain water gets in here the light is out within seconds and will then continue to play up until it's fully dried out so you must make sure it's tightly closed.

After the above soaking it started working again after a few hours in the airing cupboard but two days later it died completely and on taking it apart it was still full of water. Once dried out completely it's worked faultlessly ever since.

Overall the Moon is an impressive package in terms of light output, build quality and price, £39.99 is a tenner cheaper than the slightly brighter TraceR. The brightness gives plenty of confidence that you'll be visible even on the lower levels and the brightest mode is a bonus in thick fog even in daylight.

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?

The Moon Shield 60 is up there with the brightest rear lights on the market though the option of five modes you can select one that is appropriate to the conditions. I found it confidence inspiring knowing that drivers should be able to see you even in amongst traffic and streetlights, providing they're looking of course.

The shape and lens design provides a good beam pattern and plenty of visibility. The bracket isn't the most sturdy but didn't show any issues during testing. The Moon is supplied with a belt clip also and there is the optional saddle rail mount.

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

You must make sure the USB cover is closed, other than that it passed all soaking tests.

Rate the light for battery life. How long did it last? How long did it take to recharge?

The burn time is pretty good considering the lumens it's putting out though not quite as good as the opposition from Exposure. In varying conditions I was getting the quoted burn times -5%

Standard - 20 lumen - 5hrs 40mins

With 20 years of road cycling and over 150,000 miles in his legs it's safe to say Stu is happiest when on the bike whatever the weather. Since writing his first review for back in 2009 he has also had a career in engineering including 3D-CAD design and product development, so has a real passion for all of the latest technology coming through in the industry but is also a sucker for a classic steel frame, skinny tyres, rim brakes and a damn good paintjob.
His fascination with gravel bikes is getting out of control too!
