Review: Light & Motion Seca 2000 Race

Lights Lights Shootout

This used to be the Seca 400 many moons ago and it grew up to be the Seca 1400 with 1400 Lumens. It was plenty bright but the price was too much at $700. Last year, they increased the brightness and efficiency to put out 1700 Lumens in a beam pattern that puts the light where you need it. The latest incarnation of this groundbreaking head unit is a 2000 Lumen powerhouse for $500.

But the real story is still the beam pattern as much of the light is pointed to the ground and the sides. Very little of the light is wasted into empty space. So hats off to Light & Motion for reviving one the best designed light heads ever made in the bike market.

But the design is old and it really is due for a redesign. Light form factors have moved on now to smaller head units, shorter cords (or no cords at all) and more integrated batteries that can be mounted on the stem.

The Taz 1000 and Taz 1200 are good alternatives, as they sport a similar beam pattern but in a flashlight package.

  • Beam pattern, beam pattern
  • Light is not wasted on the top where it usually doesn’t reflect off anything
  • Excellent battery and charger
  • Mount is desceptively simple yet effective. It is very easy to adjust or transfer to another bike.
  • Excellent packaging as they’re using older, unused boxes to save resources
  • Extra long cable and huge connector is not ideal
  • No ideal helmet light in the Light & Motion line to complement it

Handlebar mounting is done with very slick strap that can be tightened based on the rider’s preference. The same strap is used for standard and oversized handlebars. At first we found the strap too long and found the excess bothersome but we realized we can loop the strap back in the pin and tuck it neatly. It can be aimed left to right.

Mtbr Light Meter Measurements

This light measured 170 Lux on our ambient light measurement facility. The light output measurement is performed by placing a Lux light meter beside the light. Both are pointed at the ceiling (five feet above) of a dark room. This measurement uses the ambient light produced by the bike light.

Integrating Sphere Measured Lumens

This light measured 2022 Lumens in an integrating sphere. Claimed Lumens by the manufacturer is 2000 Lumens. The Lumen-hour graph below shows how the light performs over the first three minutes of its battery cycle.

The location is useful since it has walls and a ceiling that can display a bike light beam pattern. The walls have a lot of graffiti on them and actually show detail when they are lit up by a light with a wide angle. Cones and targets are set up with the far target set up at 120 feet.

    Perhaps they could use a redesign of the battery and switch options etc. However, one of the best features of the Seca is it’s beam pattern, always has been. In the tunnel pics you can see the Wilma while throwing 30% more light down the tunnel does not do as good of a job lighting up a wide area in front of the bike.

    Also I’d still like to see more programmable brightness options. One thing these super bright lights do best is run times at lower brightness. Take the Wilma 7 that can run 4 hours at 1100 lumens, or the Trail LED turbo that can run 600 lumens for 38 hours. To me the longer run time at higher brightnesses is more important than max brightness for 1.5-2 hours because my rides are longer than that.
