Exposure Spark
This was the mighty atom of the test, giving out a huge amount of light from a tiny source – an incredible 220 lumens at full power.
Amazingly,all this power comes from two lithium batteries. Fitting the ExposureSpark to your bike is as simple as pulling two tie wraps in place; it really is that easy.
A CNC-machined, well-sealed metal case makes the Spark bombproof. It can be clipped on and off from your bike in an instant and doubles nicely as a hand torch. Operation is push button, and light options are high, medium and low, plus a flash mode. At 72g this was the lightest unit on test by far, and finally there’s an option to add a rechargeable battery pack, which takes the price to around £110.00.
