MBUK Magazine selected the Gemini Titan 4000 Lumen for their 2016 Test Winner.
Gemini's TITAN shows it's not just what power a light packs - although it's very well endowed in that department - but how it puts it on the trail that matters. It's basically three Gemini Duo lights side by side in a shared housing, with the six LEDs pumping out up to 4,000 lumens. The wide spacing of the LEDs creates an astonishing blaze of broadly spread but extremely far-reaching light.
Because the multiple sources don't suffer from cable shadows and overlap on the ground, the quality of trail detail you can see is in a different class to any other light here. That makes the 40 per cent 'medium' setting more than enough for most trail situations, with an instant-connection remote switch making mode changes easy. Each mode can be programmed in 10 per cent steps if the default doesn't suit you. The two O-ring mounts at either end of the lamp now come with taller spacers so the centre clears bigger stem faceplates, even on minimal rise bars.
We've been running Gemini Lights of all shapes and sizes for years without a single lamp, battery or connection issue and not much performance degradation either. Charging is relatively fast too, and there's an eight-cell battery model that adds half an hour of run time for only £10 more. That means the fact that the long cloth battery can slide about is the only complaint we've got about this deceptively simple but genuinely game-changing light.
