Gemini Duo LED 1400 4-cell

Ignore the Wall-E looks of the headlamp and look deeper and you’ll see that the Gemini has a lot more going for it than it appears. The system features a twin LED headlight with a soft rubber button on the back side, connected to a four-cell oblong battery. There are a couple of extras in the box, like an extension cable for mounting the battery on the seatpost, and there’s a helmet mount too.

Plugging in, you’re greeted with a soft green glow from the power button. This can be a little off-putting if you’re following a bike on a car roof rack with the lights connected, but it takes a negligible amount of battery power and when in use, it reassures you that you still have plenty of juice. The light attaches with a strong, simple O-ring and can pivot side to side.

That single button is the key to the system. Pressing it will get you into the low/medium/high cycle, but holding it in will put you into program mode, where you can customise the power of each mode. Want a 100% high beam (1400 lumens, three hours) and then 20% (280 lumens, 18 hours) and then 10% (140 lumens, 38 hours)? It’s yours.

The beam pattern is a large smooth spot, with a steady fall off to the sides, great for most trail uses, whether on the bars or a helmet (though there’s a cheaper two-cell version for that, or for ‘hard, fast and short-lived’ riders).

Overall: Simple to use, bombproof and yet easy to program to be as complicated as you’ll need.

Chipps wasn’t around for the dawn of mountain biking in the UK, but he likes to claim that he arrived in time for second breakfast (about the time he shows up for work, then…) starting in the bike trade in 1990 and becoming a full time mountain bike journalist at the start of 1994. Over the subsequent quarter century, he has seen mountain bike culture flourish and diversify and bike technology go from rigid steel frames to fully suspended carbon fibre (and sometimes back to rigid steel as well.)

His riding style is best described as ‘medium, wheels on the ground, trail riding’ though he’s been spotted doing everything from endurance downhill racing to 24 hour cross country racing. He favours mid-travel trail bikes and claims to be wheel-size, gear, brake and tyre agnostic. In fact, his garage spans most bicycle flavours, taking in steel hardtails, carbon trail bikes, even a mountain bike tandem, along with road, touring and gravel/cyclocross bikes.

While he’s happy to chat about bikes all day, his real interest is in the people and places that bikes can introduce you to and he talks as fondly about the trails he’s ridden and riders he’s met as the bikes that took him there.
