The aptly named Spark is a tiny but deceptively powerful bike torch that makes a great helmet option or backup light – it’s expensive though. The output is a tightly focused beam, with not much in the way of peripheral infill to put the trail in context.
This means that while a bar mount is available, it’s definitely best used on your bonce where you can direct the light accurately. A clever vent clamping helmet mount is included to give a super-secure but easily adjustable fit, and there’s an optional leash too.
While there are three power options, we found ourselves using the brightest, but you can fumble along on the medium setting if your bar light fails. Even at full chat you get nearly 3.5 hours with conventional CR123 batteries or slightly less with the rechargeable cells that are bundled with a charger in the Spark Pack.
If you’ve already got rechargeables, you can buy the Spark light alone for £80. Exposure’s Joystick – with the same power but Smart Port versatility and internal Li-Ion battery – costs £165.
Road use
The above review and rating relate to the Exposure Spark's performance off road. So how is it for road use? Cycling Plus put it to the test, and this is what they had to say:
For a little unit, the Exposure Spark packs quite a punch. On full power it gives out a good pool of light for riding quite quickly, and although the side visibility could be improved, it’s still a capable little commuter light. The mounting is simple, and it’s easy and quick to install and remove even with gloved hands. The illuminated switch also doubles as a mode and ‘fuel’ gauge, telling you how much power’s left.
★★★★
