Gemini hasn’t significantly changed its unique Titan light since it appeared a couple of years ago. That’s not a problem however, because the unique six-LEDs-in-a-line layout still puts it in a different class to any other unit, in terms of the most texture rich and easiest to ride with the light output available.


While it looks like its just stuck three of its Duo 1500 Lumens lights side by side, the Titan actually uses a single dedicated casing. Power is also throttled back slightly to 4,000 lumens at full bore. That’s more than enough for any situation I’ve used it in, and the default medium setting is ample for aggressive riding on technical terrain.

While reach and spread are impressive, it’s the way the Titan illuminates the trail that really stands out. The six light sources all overlap at fractionally different angles to give eye-friendly, multi-point clarity that makes crucial trail details much easier to decipher in 3D, whether they’re distant or right under your front wheel.

Alter each of the three power settings in 10% steps to get your ideal working range

The broad multi-aspect beam also means a complete lack of singular brake/gear cable shadows, which can easily glitch your vision and/or cause premature eye tiredness.

You can alter each of the three power settings in 10 percent steps to get your ideal working range. Switch instantly between the different modes or ‘dip’ the light to avoiding blinding oncoming traffic via the wireless remote switch, which also simultaneously links to a Gemini headlight. That means the slim six-cell bag battery is more than ample, but an eight-cell version (£324.99) is also available if you need extra run time.

It’s awkward (but not impossible, with an extension cable) to helmet mount, and the lamp may need spacers under the mounts if you’ve got a lumpy stem and a flat bar. Otherwise reliability of every Gemini light I’ve used over the years has been faultless, pricing is reasonable and the illumination it provides is literally brilliant.
