This is the daddy of all the Exposure lights, featuring the brightest output and the longest run time. With two 5 watt LEDs up front in a spot and spread set-up, this self contained system is powered by a compact 7.4-volt 4.3-amp/hour lithium-ion battery.
The light output on Turbo mode is impressive for an LED system, and the run time in high mode is an impressive four hours or more (depending on temperature). The mounting is a little on the slender side and only fits the size it is made for, meaning you have to choose the right one when you buy the light.
Previous versions of Exposure lights had the charging socket hidden by the mounting, but now a new waterproof charging socket is in use and there is no longer any need to remove the light for charging. Removing the light is what we would suggest though, given that it wouldn’t take much to steal it from a locked up bike, but this requires a 4mm allen key – a little fussy for those everyday commutes. The quality of light and the peripheral vision spread is great – more than enough for riding at speed, and even better when switched into Turbo mode.
