Light and Motion’s Seca Comp 2000 is a three-LED all-in-one unit that boasts a 2,000-lumen max claimed output and has an IP67 dustproof and waterproof rating.
Weighing just 224g including the bar clamp, its diminutive dimensions don’t necessarily mean a lack of power.
The three CREE LED setup shines through two spot lenses and a single lower diffusor optic.
Its four modes are cycled using the power button, while a secondary smaller button cycles through the three-mode orange sidelights, designed for on-road visibility.
The main button changes colour from green to red as the battery charge depletes, although it doesn’t change colour based on the selected mode.
Designed for handlebar mounting, the rubber ladder-style strap is compatible with bars up to 35mm in diameter, and a GoPro style mount is also supplied.
Light and Motion Seca Comp 2000 performance
Although the Seca Comp 2000 feels like it has more power than claimed, there isn’t quite enough light to truly illuminate every obstacle on the trail, with some roots and rocks, especially off to the sides, remaining in the dark.
Its power isn’t low by any means, but the wide-spread beam pattern shares out its limited lumens broadly. This means it lacks the intensity other lights with more power and a similarly broad spread have.
The broad beam pattern has no discernible cut-off, either, so the light transitions to dark imperceptibly on the trail. This means it’s possible to see lines around turns and off to the side of your direction of travel.
Although the beam pattern is impressive, the low output means that total illumination is meagre, making the Seca Comp 2000 better suited to slower trails with fewer technical sections.
On this type of terrain, it is truly brilliant. Surprisingly, there’s plenty of throw in front of the light, so I never felt I needed to angle the light higher to improve its reach.
The LEDs have a green and yellow hue, most noticeable in a forest with corresponding natural colours.
This means it’s easy on the eyes and there’s no glare or dazzle. But because of the lack of power, it lacks a little pop and definition.
When I tested run time, the Seca Comp 2000 lasted 1hr 20mins on max power, about 10mins less than Light and Motion claims.
Operation is simple via the large illuminated button. However, it is stiff to push, making it tricky to change modes on the move without accidentally pushing the light body down.
And while the mount is simple to attach to the bar, I couldn’t get it tight enough to stop the light slowly angling down over the course of a descent, meaning I had to stop to readjust its position every minute of riding or so.
The light is supplied with a GoPro-style fixing that mitigates this problem, but you need to already own a bar or helmet-compatible mount to attach it to.
Light and Motion Seca Comp 2000 bottom line
With a fantastically broad beam pattern, the Seca Comp 2000 is a promising light. Technical terrain is its main pitfall due to a lack of power, and the rubberised strap isn’t that secure.
It would suit a casual night rider looking for an adaptable light for both road and mountain biking.
How we tested
For our 2021 MTB lights test, we put eight units to the test, starting at just over £100 and rising all the way to nearly £500.
Whatever your budget, there should be one that will suit your needs.
Of course, there are plenty of lights available online for less money, but they won’t necessarily offer the same reliability or aftersales support as the trusted brands tested here.
All the lights chosen have a minimum output of a claimed 1,500 lumens, but some are much brighter. Generally, more lumens equates to a higher price.
As well as testing how each light performs on the same trail on back-to-back runs – assessing beam pattern, LED colour, ease of operation and, most importantly, light projection – we also timed them all on max power to find out just how long the batteries last, and whether they live up to the brand’s claims.
