Product Description

The Gemini DUO front bike light is ready for any ride with lumen settings ranging from 150 lumen up to a huge 1,500 lumen. You can use the Gemini DUO for your morning commute, then your post-work trail adventure. At 65g this Gemini bike light is one of the most powerful for its size on the market. Plenty of brightness modes and mount types make for an extremely versatile bike light.  

1500 Lumen Headlamp

By squeezing 1500 lumens inside headlight weighing just 65g, the Gemini DUO LED Light has a power to weight ratio that would make a supercar blush. It gives you the power to perform on the road, on the trails or anywhere else you decide to test yourself.

The average car headlight produces 1200 lumens, so if you find the Gemini DUO’s 1500 lumens are a few hundred more than you need, we’ve got you covered. The Gemini DUO is fully programmable with 10 brightness intensities at your disposal to match whatever environment you’re exploring.

3 Mount Types

Super bright, tiny and lightweight, the Gemini DUO is the perfect head mounted lamp to take on any challenge and is equally happy as a solo handlebar light. To help you perform from dusk until dawn, the Gemini DUO comes with head strap, helmet and handlebar mounts, to ensure you’ll never be left lacking.

Absolutely Amazing

Like most folk, I spent weeks researching different lights. And I couldn't be more pleased with this purchase. The light itself is small and compact with incredible visibility. Having the separate power pack was exactly what I was looking for. I ride with a rucksack 90% of the time so the size/weight of the 4 cell doesn't bother me. One thing that's truly awesome is the handle bar mounted remote. I wasn't sure how much i would use it at first but now, it's a must for every ride. Being able to change the brightness on the move without taking a hand off the bars is fantastic. Also being able to flash other road users is pretty handy too... All in all a fantastic light that I would recommend to anyone looking to invest in one.

Outstanding light, tiny and powerful, weighs next to nothing. One offer on top of another offer from Tredz made it an unbeatable price too.

Very bright, great for dark rides!

I purchased this after extensive research and am very pleased with it. The light is tiny, and exceptionally bright - more than adequate for night riding along unlit lanes at speed. The battery pack doesn't fit particularly nicely on my frame, but I'd rather the separate replaceable battery pack to a larger all-in-one light on my handlebar. Overall, I'm pleased with the purchase and haven't found another light I'd rather use in the price range.

gemini duo

This is a brilliant light. I have used a lezyne in the past and this blows that out of the water. It is extremely bright and the fact it comes with a helmet attachment is fantastic. I purchased the 4 cell which gives a few extra hours of battery life. The only minor downside is the size of the battery as it is quite heavy and bulky. If the light itself was rechargeable by USB like other lights then it would be absolutely amazing but this is only a minor gripe on my part other wise can't recommend enough

Bike Lights Guide

What are bike lights?

Bike lights are vital accessories which attach to your handlebars, seatpost, helmet, bag or jersey. Their function is simple – to help you to see and be seen.

Who needs bike lights?

Everyone needs bike lights! It’s a legal requirement to use front and rear lights on your bike between sunset and sunrise, but they are also useful when visibility is poor – in the fog for example.

What are the choices?

Light technology is ever evolving and the choice is enormous. Always think “the brighter the better” and look for a higher lumen output when choosing. There are lights that run on batteries or beams which can be recharged via plug or a handy USB socket (great for topping up at work). Some lights have battery packs and most have a selection of modes to choose from. You’ll definitely need the brightest lights if you ride wooded trails as you’ll really need to see where you’re going!

What should I buy with them?

Spare batteries are handy if your bike runs on these, as is a charger if it’s rechargeable. Spare mounts are always useful, especially if you have more than one bike. A helmet mount points the beam where you’re looking, rather than the direction your bike is pointing.

Anything else?

Don’t get caught out – a spare back up light is a great purchase in case your ride goes on longer than anticipated or the lights go out earlier than expected. 

See our Lights guide for more.
