A small light with plenty of modes to cover all eventualities

Update to review published Nov 2017

The Moon Meteor Vortex Pro offers a decent amount of brightness matched by some impressive burn-times. Nine mode choices could see you really stretch out that battery life too.

The Vortex Pro is quite a small unit compared with a lot of the lights on the market today, especially those that boast an output of 900 lumens, as the Vortex Pro does in its Boost mode.

It uses a single Cree XM-L2 LED and what looks to be a simple lens and round concave reflector to deploy the light in a very torch-like way: a central spot which Moon claims has an angle of 17 degrees before fading out to 80 degrees.

It's not perfect for road use where a wider, flatter beam is better to reduce the chances of dazzling oncoming traffic, but angled down I didn't seem to irritate anyone while still getting the light shining up the road. You need to have a bit of common sense and courtesy with the lumen output too.

You get four solid modes: 700/400/200/80 lumens, plus give the button a double tap to get that Boost mode.

On main roads you can easily get away with the 400-lumen setting which also has an impressive 4.5-hour burn-time. There is enough light there to be able to see a decent distance ahead and pick up potholes and the like, though if I switched onto the back lanes I'd step that up to the 700 lumen, especially if things got a little twisty.

Each mode is selected by pressing the top button and you cycle from bright through dim, although the light does have mode memory so whatever mode you turned the light off in is the one it comes back on in.

The mode display changes colour to let you know where you are, and sitting just in front of that is the battery display which changes from blue through red as the power drops.

Moon keeps the flashing modes separate, which I like, so you are never scrolling through a disco on a technical back lane to get to a steady beam.

You press and hold the button for a few seconds to swap from steady to flash, and then you have another four flashing modes plus an SOS setting.

FL1 and FL2 are simple flash modes with 20 lumen and 100 lumen respectively, with FL3 offering a 400-lumen flash while the LED stays on at 20 lumen output. It's similar to Exposure's pulse mode where the light never actually goes out.

DF stands for Day Flash and it is a double shot of 400 lumens, plenty bright enough for you to be noticed on a sunny day as you filter through traffic.

All of the burn-times here last for absolutely hours too.

The button is a little on the small size, plus it is quite stiff which did make changing the modes a little bit of a faff on the fly.

Resistance to the weather is always a concern for use in British weather. The Meteor Vortex Pro is rated to IPX4, which basically means it'll withstand splashing water from any direction. Alongside riding with them in the rain, I also like to give all the lights I test a good soaking from the bathroom shower to replicate really heavy rain. The Moon sailed straight through with no water entering the battery compartment, lens or charging port.

You'll find the charging point underneath and it uses the small USB type found on most mobile phones. It's protected by a small rubber cover.

Charging from a flat battery takes four hours. Once full capacity is reached, the light reduces things down to a trickle charge to reduce the risk of damage.

The light itself is pretty robust. The front half of the body is made from aluminium, which easily resists being dropped onto the road without issue. I would like to see a better warranty though: one year for workmanship or material defects and a mere 120 days for the battery doesn't seem long enough to me.

Fitting the light to the handlebar is a simple affair, with a bracket that uses a rubber band style clamp. The neat thing is the little nub that you fit the rubber band around is hinged, so the bracket can be used on any shape bars, even aero wing style. It's a snug fit too, and sees very limited slippage, though you might get a touch if the road is really rough.

Price-wise, £69.99 is pretty good for a light that chucks out this much power. The Cateye Volt 800 costs an extra £20, the Giant Recon HL 900 is £79.99.

For the whole package I'd say the Moon offers a sensible price for what you're getting, and even putting the few little niggles aside it makes a great general purpose light.

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 road.cc 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!

I bought one of these for use as an off-road helmet light.  Overall it's a great light, but two minor niggles.  Firstly, it's often sold as having a replaceable 18650 battery.  In fact, it's a proprietary battery (basically an 18650 with both terminals on one end of the battery), which means you can only use Moon's own batteries which are quite hard to come by.  Still, the ability to carry a spare battery to extend runtime without more weight on your head is a bonus.

Secondly, the included helmet mount only has very coarse settings for angle.  The light has a fairly tight beam, which is great for a helmet light, but means that getting the angle right is critical.  For me, one position on the mount is too low, and the next click up is too high.

Merlin have these lights for £45, although you have to Google for it.  The site search only finds the less powerful non-Pro version.

The best bike light is a regular flashlight... specifically the 1,000 lumen Nitecore MH10 ($45) with an Exposure Quick Release Mount plastic bracket ($20).

It is USB rechargeable, uses a standard 18650 battery, puts out a lot of light, and is more compact than most all of the dedicated bike light options.

The problem with that is the big difference between the High (1000 lumen) and next setting (240 lumen) plus the fact that the high output is on a 5 minute timer before it automatically drops to the lower setting means it is not very good as a bike light.

Bike lights have a specific design characteristic for a very good reason.

I have the less powerful non-Pro version of this which does 300 lumens for 3 hours or 600 on boost for 1h30. I rarely need the boost mode even on unlit lanes but then I am generally averaging 16 mph on known roads. It is a very good commuting light for my purposes and cost just £30.

It will run off a powerbank if required for longer rides, and the USB cable supplied has a oversized head on it which fits securely into the charging socket surround for such purposes. Or spare batteries are available too, 3350 mAh compared to the 2200 mAh supplied with the light.

I have one, good light output and reasonable battery life for winter training rides. Beam shape is basic, but does OK.

As per the review, switch is a bit fiddly to use with gloves on, but the remote switch is easy (too easy?) to flick between modes. Far better than the Lezyne 600/800XL.

Eventually bought this light for £48 from Merlin after days of research. Had trouble finding the batteries but I eventually found them on ebay for £14 rather than pay the £20 or £21 that most retailers were asking for .


£14 for one 2600mAh is such incredibly bad value for money...
