Expensive, but excellent light distribution, run times and reliability for uncompromised trail riding
Skip to view product specifications

L&M have tweaked their top-of-the-range Seca to create a safer but still super-powerful off-road light for the more minted rider.


The first thing we checked when running the Seca was the cooling fins on the back of the lightweight head unit, as last year’s sample got burning hot. Good news is that this unit runs much cooler despite kicking out more power from its double decker three-LED arrangement.

L&M’s custom optics concentrate power along the top edge to give a decent, detailed throw down the trail. They also put masses of light either side of the trail from your front wheel forward, which is great for bar use on twisty, slow-speed trails.

The lamp weighs little enough to work well with the supplied helmet mount and extension lead. It’s powerful enough for a good pace even at ‘cruise’ rating. The rubber belt bar mount also seems a lot more secure and stable than last year’s version.

The four-cell battery is pretty chunky so frame fitting can sometimes be a jigsaw puzzle but run times are impressive. Excellent L&M reliability offsets the high cost.
