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.

The Gemini Duo 2200 Multisport Front Light is a powerful offering that is good enough for use on the trails and for lighting your way on the road. It really pumps out the lumens, all from a comparatively small head unit, although the fact that the battery pack is quite bulky might put some off.

You can divide lights into those designed to be seen and those for seeing with. This Gemini is firmly in the latter category, pumping out 2,200 lumens, which is more than enough to light even the roughest off-road trail.

All of this is done through a small unit that can be attached to your bar, your helmet, or even worn on a head strap. As the name suggests, this light has a variety of uses – I even found myself using it while crawling around under the floorboards during the review period. Gemini is quick to highlight that this isn't simply a bike light but is very much designed for multiple sports.

Rather than relying on an internal battery the Gemini has a separate battery pack, which is about half the size of a pack of cards. I used the included Velcro strap to hold it in place underneath my stem, which kept it out of the way, although it is a bit bulky. Finding the ideal spot is made a little more complex by the wire, which is only around 12 inches long and needs to be connected to the light without being permanently strapped to the frame.

This also made it less appealing to use mounted on a helmet. Although the head/light unit itself isn't hugely heavy, the length of the lead means the battery has to sit on the helmet too (you can't store it in a pocket, for example). The weight of the battery isn't enough to give you neckache, but you certainly notice it. You can buy an extension cable for around a tenner, which gives you an extra 70cm to play with, so you could keep the battery in a bag or a jersey pocket.

Attaching the light to the handlebar is done through a simple rubber loop that sits on hooks either side of the head unit. I found that this kept the light in place over rough surfaces and it never threatened to come loose. All good there!

With the battery, the entire unit comes in at 253g – not light, but still lighter than some powerful integrated lights such as the Exposure MaXx-D MK11, which pumps out more lumens (3,300) but weighs 80g more (and costs another £155).

Modes and run-times

Battery life is impressive: 2 hours for the maximum 2,200-lumen solid beam, 4.5hrs for medium (1,100 lumens), and 22 for low (220 lumens). Out of the box there is perhaps a little too much disparity between the medium and low settings, but handily you can reprogram the modes using the single button on the back, so you could pump up the output on low or lower the output on medium, for example. All the modes are programmable with 10 different brightness levels; it takes a little bit of practice to get it right, but after a few attempts it's relatively simple.

There are also two flash modes, with run-times of 4 hours on the maximum output flash and 21.5 hours for the lowest setting.

Changing modes is done in one of two ways: either pressing the one button on the back for different lengths of time, or using the included remote. The remote is a really neat feature as it allows you to not only shift through the modes, but also lets you dip your light, something that is necessary on the road given the power of this thing.

The remote is simple to connect – you just need to press the buttons on the remote within 30 seconds of connecting the battery to the light.


I used the light almost exclusively for road riding and found it more than adequate for most situations. The beam pattern is pretty much a perfect circle in front of you; it means you can see what's exactly in front from far off, but you perhaps don't see as much laterally as with some other lights. Personally, I didn't feel I was missing much compared to when using a wider beam; I found that I could cycle faster with more confidence because I could see further – I could see potholes coming up with more than enough time to adjust, for instance – though I was aware that there are no side windows to help with visibility at junctions or with vehicles approaching from the side.

I didn't really use it too much off-road, but I can see this working just as well for gravel or even mountain biking in the dark. I'd suggest saving the helmet mount for riding off-road and on gravel because it's easy to dazzle other road users with powerful helmet-mounted lights.

Like many, the single button on the back of the light also works as a battery level indicator through a coloured LED that goes through green, amber and red. On the battery pack itself five LEDS indicate the level of charge, to give you a little more accuracy.

Charging is done through a USB to USB-C cable and takes around five hours from empty when plugged into the wall, longer through a laptop.

When it's not being used to power your lights, you can use the battery to charge your devices using a USB-C cable.

Value and conclusion

An RRP of £229.99 is a lot of money for a bike light, of course. The Gemini Duo 2200 Multisport does have a multitude of uses, though, which goes some way to justifying that price. You can also pay more – a quick look at this year's beam comparison shows a few Exposures that are more expensive (the Strada SL is the closest in price at £210, with a max output of 900 lumens), and the Lumicycle Apogee is £419.99.

Overall, there is no doubt that this is a more than powerful enough light for a multitude of uses, and the remote works brilliantly. The fact that the head unit and the battery are separate makes mounting a little more complicated than with a self-contained light but this is still a strong proposition.

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?

It is a powerful wearable light that can be used across multiple different sports.

Gemini says, 'The Duo 2200 Multisport is designed to be your primary go-to light for all headlamp needs.'

Off the bike I found this light really useful as a headlamp although, personally, I found it a little too bulky to be put on a helmet for road use. It performed well when mounted on the bars.

Rate the light for quality of construction:

Very well made, it feels sturdy and reliable – especially with the rubber encased battery ends. I'd be confident that I could throw it at a wall and the wall would come off worse!

Rate the light for design and ease of use. How simple was the light to use?

Once on the bike it is easy to use, with only one button on the light itself controlling everything, and it also has a very easy to use wireless remote to give you more control on the fly.

Rate the light for the design and usability of the clamping system/s

This is a bit of a mixed bag... both the light and battery stay in place well, but the challenge is that the battery is fairly bulky, so finding places to attach it can be tricky.

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

No issues at all with water getting in.

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

Impressive, especially given that with the reprogrammable element you can select whether you want to sacrifice brightness for battery life or vice versa.

Rate the light for performance:

Performed well throughout the review, pumping out plenty of light and including some nifty tech touches.

Rate the light for durability:

Waterproof and unlikely to break any time soon.

Rate the light for weight:

This is quite a difficult one to judge given the complexity of the system, but it's lighter than many lights with a similar lumen output with integrated batteries.

Rate the light for value:

It's not a cheap light by any stretch of the imagination, but it does cost less than some lower-output Exposure lights. It makes a fantastic multi-sport headlamp and the head strap, in particular, is brilliant. For use only as a road cycling light it perhaps doesn't justify the price, but if you're going to use it for mountain biking and perhaps some non-bike activity too, it starts to look better value for money.

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

It performed well and has some really good features, like the remote and the programmable modes.

Tell us what you particularly liked about the light

The programmable element is a really great feature.

Tell us what you particularly disliked about the light

The separate battery makes it very useful for mounting the light itself and lends itself well to multiple other sports. Mounting the battery to the bike is a little fiddly, and I felt that the lead could be longer.

How does the price compare to that of similar products in the market, including ones recently tested on

It is lighter than the USE Exposure MaXx-D MK11 which pumps out more lumens (3,300) but weighs 80g more and costs £155 more.

Did you enjoy using the light? Yes

Would you consider buying the light? If I was looking for a multi-sport light.

Would you recommend the light to a friend? Yes, if they were looking for a multi-sport light.

Use this box to explain your overall score

It's a difficult one to score, though there's no doubting it's a good light; for purely road cycling it is perhaps overkill, but as an all-round multi-sport light it's great.
