Mr BellNice light - great visibility
Mr TurnerGreat little light for the money. Super bright. Feel a lot safer when I use it
GeoffThis is a superb rear light - extremely bright and when used with daylight flash mode will literally last all day. This is the 3rd of these that i have purchased - not because they cease working but because they get lost. Currently all 3 are found!
Mr BartlettExcellent rear light - pay a little bit extra and you get better quality and brightness
JohnEasy to use and bright. Great selection of attachment hardware included — especially seat rail clamp. Sensible and easy to use push button menu to toggle between modes.
GrantBright light, multiple mounts, multiple lighting options, rechargeable and a good price. So good thinking of replacing all my old rear lights with this model.
Mr FinchBright light in a smart and small unit
Mr HoughThis light is bright! Had the front moon comet x light already and impressed with that so Bought this as a back up light in case my other light fails
Mr CooperExcellent rear light especially for the price. Handy that it is rechargeable. Easy to fit to bike with the accessories provided.
ErneGood product. Light, powerful and with good aero profile
Mr ChrzanCompact bright light with good variety of mounting options including seat rail.
KrzysztOFF SWell made, strong light, plenty of mounting brackets, long lasting battery
AdamBrilliant light, feels solid, usb charge, plenty of modes for different situations, no excuses for traffic not seeing you with this beauty!
Graham of KidderminsterVery bright on full power, but lasts forever on a charge at the lowest level, which is all you need under street lighting. Well made and a good price for this quality.
Mr SpencerThe light is very good. I wanted a bright daylight flash light with a good battery life. The spec on the rear light is 80 lumens for 19hrs. It is bright and whilst I haven't confirmed the run time, no issues on two long rides without further recharge. The light comes with several ways of attaching the light to the bike and also a waterproof USB charging lead. A plus is that the square mounting lug seems to be industry standard and fitted the mounting I already had on my Topeak seat post bag from my old light so a seamless fit. Happy to recommend.
Mr PrzyluckiSimple but reliable, just ordered another one fro a club member who really liked the strength of this rear light.
JanUsed extensively over autumn/winter season. Very bright, good battery life, properly sealed, no issues.
BrianA very good tail light. Bright and long lasting. I like the mounting options that come with it, especially the saddle mounting bracket, this put the light in a visible but protected place. My only negative is that the light is quite hard to switch on/off. The rubber covered button does not have a positive feel. Other than this it is a great little light and I am very pleased with it.
StashDoes exactly what it says on the tin. I ride mainly in the daylight so have the light set to daytime flash mode, the charge lasts for ages in this mode & increases visibility. I find most drivers give you more respect if they think you're taking precautions such as this light.
markSuper bright! What more can be said. The rating does not do it justice. It’s SUPER bright. It also comes with a wide range of mounting options that will suite any application. I’ve used other main stream brands and this is my fav.
Miss ShearerCompact with multiple light modes and supplied with different quality bracket mounts.
Mr SchmittVery bright with an excellent design. Flash frequency is not a rapid blink, which may be too slow for some.
DavidMoon lights have the best battery life and offer really good value. This one is bright and runs for days on flash only. As a night light I get four hours - or more if warmer.
JJ TANVery bright and good quality light with affordable price tag. Love the saddle rail bracket
RobertOnly had it a few days. So far so good. Very bright. Great set of modes. Great mounting options. Rail mount is the one I really was a little tricky to install due to the seat head mount; got it on in the end. Highly recommended.
Mr Inuigood
JJVery bright and good price. My second purchase
TomExcellent tail light, comes with many mounting options, highly recommend
SteveGreat light, best I`ve owned. Lots of mounting options , very good quality .
L davidsonI`ve always had trouble getting a decent rear light that works - that was until I purchased this light - it is amazingly bright + the battery power is good, does it exactly what it says on the box. Great buy.
JohnKGood light with plenty of lighting and fixing options. I`ve been using it on daytime flash using the belt clip to a bag. Good battery life. The switch is just a bit fiddly with gloves, but not a big problem Good price and usual excellent service from Merlin.
Mr SAWFORDSmallish neat light fits well on my aero seat post with a good bright LED bulb so I can be seen when riding at dusk.
BarrySmall, light, very bright and versatile fitment.
LarsGreat lantern that makes you visible from behind. I really like the way you put it on your saddle. Has different modes and brightness.
Mr RazvanAfter the reviews of this item find on google, I had to try it. And I'm very glad I did. The product has very high quality materials, the light can been seen from a wide angle and it is very powerful and pleasant too! Definitely a must try and have product. Thanks Merlin for you're service! (The package has arrived in 3 days, very fast considering that I'm from Romania)
Mr RajalaA versatile & professional rear light. I really like the saddle rail mount that came with it, it's sturdy and aligns the light perfectly. The light itself has enough power for any use I think. Burn time seems to be adequate at least in low & mid setting. The light has not let me down even once (Finnish winter weather, everyday city use). Great value for little money.
Mark HGreat product.. easy to install and its super bright even on the lowest setting. The highest setting is like a camera flash! So you won`t have to worry about not being seen. Parts and actual light all feel really high quality
Mr FernandesVery satisfied. Even with minimum intensity, the cars when approaching give much more room than before.
Steve CostiganGreat little light, comes complete with saddle rail mounted bracket-perfect for a reverb seat post!
ShaneThe first time I used this product, cars seemed to give me a wider birth. It is 5 times brighter than the back light I already have. Excellent product
Rich TongWhat a great rear light this is. Well made with loads of functionality and mounting options too. I went for the seat rail bracket, which was a doddle to install and keeps my seat post clean and aero. For the lumens it emits it weighs a feather too. No water ingress after several wet rides and Merlin's sale price was cheapest by far!
Mr AtkinsCompact but very bright and a good price. Easy to assemble and install and gives a little more confidence on the roads.
Ms barfootGreat light, very bright and fits onto the seatpost without any tools, uses an O-ring type device to do this. Would recommend.
Mr JacksonThis an excellent daytime safety light. Very bright with a long run time on the daytime flashing mode. Very light and unobtrusive, with an excellent clamping system, which adapts well to handlebars, stems and even forks!
Mr HARTLEYThis is my second "moon" rear light, and the "Comet-X Pro Rechargeable Rear Light" is a step up from the last "Comet" rear light for sure. It's small enough to tuck neatly underneath your saddle, (and if you turn the under-seat mounting bracket upside-down, then the light is totally unobtrusive, and a saddle bag fits as though the light wasn't there). This light is super bright in both constant and flashing modes, has a great battery life, and weighs virtually nothing. Worth the full RRP, but an even better buy when on offer at Merlin Cycles.
Mr LAUGreat that it includes a saddle mount, but preferred the more simple design of Comet MK II where you can just wrap is around a seat post without an additional bracket. Also, would like to see a lower output on the lowest setting for group rides, it used to be 6 Lumen, now the lowest setting is outputting 15 Lumen already.
Mr RobbAn excellent rear light that is bright and easy to attach. Several attachments are included to enable you to locate the light according to your preference. Light provides several modes re brightness flashing and riding time
JasonAn impressively bright and compact light. Battery life seems decent on the "flasher" setting I have been using. There are numerous modes of operation to suit your needs. I can't really comment on long term reliability yet as I've only had the light a couple of weeks and it hasn't seen any wet weather.
