Light & Motion Seca 1700 – 2013 Mtbr Lights Shootout

Lights Lights Shootout

This used to be the Seca 400 and last year it grew up to be the Seca 1400 with 1400 Lumens. It was plenty bright but the price was too much at $700. This year, they increased the brightness and efficiency to put out 1700 Lumens in a beam pattern that puts the light where you need it. They dropped the price to $469 so the Lumens per dollar now tells a very compelling story.

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.

Specifications:

  • Price: $469
  • Claimed Lumens: 1700 Lumens
  • Measured Lumens: 1815 Lumens
  • Measured MTBR Lux: 180 Lux
  • Light Head Weight: 131 grams
  • Installed Weight: 326 grams
  • Run Time: 1.5  Hours for the ‘Race’ model tested here.  ‘Enduro’ model runs for 2.5 hours
  • Category: High End

Strengths:

  • Beam pattern, beam pattern.  It’s very wide and the 1700 lumen model is finally enough light for this beam.
  • 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

Weaknesses:

  • Extra long cable and huge connector is not ideal
  • No ideal helmet light in the Light and Motion line to complement it

Mounting:

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.

Backyard Beam Pattern Photo: Compare all lights here.

We photographed the lights in the same location setting with the same camera settings. The photos were taken in the back yard that is approximately 25 yards long. These photos feature many objects and a distinct background to analyze detail and beam pattern.

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 80 yards.

      are you running the Race or Enduro version? full power, I presume? are you getting the specced 1.5hrs out of a full charge?

  • Todd says:

    They should bring back the old 9 cell enduro battery that would bump it to closer to 3.5 hours on high.

  • Joe says:

    I have 2 of those 9 cell batteries and they are Great !!!!! Never have to worry about running out of light………One powers a Seca 1400 and the other a Seca 1700

  • Joe says:
