Endurance racing calls for equipment that can withstand any situation thrown at it. That's why you built your dream bike for the next 24-hour race. And though your training and bike are dialed, your lighting situation likely needs an overhaul. After all, do you want to defect because of a blackout at 2 AM, or do you want to race the full 24? If you answered the latter, get a Light & Motion Seca 1700 Enduro on your bars and ride with confidence through the night. Made to take the rigors of endurance racing, the Seca 1700 Enduro will keep the trail lit on race day.

When it comes to settings, construction, mounting, and lumens, the Seca 1700 Enduro takes many of its cues from its sister light, the Seca 1700 Race. But, that's where the resemblance ends. Since 24-hour racing requires increased battery life, the Seca Enduro gives you just that. With its increased battery life, the Seca Endura is lighting the way brighter and longer than its competitors. And though many light manufacturers have picked up on the high-lumen craze, Light & Motion hasn't simply added lumens to the Seca for the sake of brightness, it's redesigned the light to use the power output more wisely and efficiently. Due to the Seca's bi-conic reflector, its six LED bulbs cast an intense light in a wide beam that makes you forget that it's nighttime.

Four settings on the Seca Enduro let you adjust the output in accordance to the desired application. Now, you can expect a range between 2.5 to 30 hours of light. High puts out 1700 lumens, medium 850, and low and flash are both at 425 lumens. All 1700 lumens are essential to some while descending the trail, but going up hill doesn't require firing up every lumen. Thanks to the race mode setting, you can use less light while ascending the trail by skipping the medium and flash mode -- this leaves you with the high and low settings only. And when you're ready to head back down the trail, a push of the power button has you back at full power.

For convenience, the light mounts on either your helmet or handlebars. The six-cell, lithium-ion battery comes with 127cm of cord -- enough length to stow the battery in your backpack or strap it to your top tube. It's also worth mentioning that the helmet mount works with all Light & Motion helmet compatible lights. The Seca Enduro weighs in around a feathery 495 grams -- a small price to pay for instant daylight on the trails. Along with the weight changes, the Seca Enduro also features a lower profile design to minimize any obstruction.

The Light & Motion Seca 1700 Enduro Light is available in the color Black/silver, and the battery, cord, and Mini-L 1.5 charger are all included.

Super Bright!

Amazing retina searing 1700 lumens! While this is an older model, it still packs a wallop. The actual light portion of the Seca 1700 is light and while mounted on a helmet it is barely noticeable. The only time I noticed the weight of the light it was riding downhill when my helmet would tip slightly (even then is was quite minor). That was easily resolved by tightening the retention system on the back a click or two (will vary depending on your helmet). The Enduro battery is light and can easily be stowed in a jersey pocket.

I would recommend an extra velcro strap or any other type of easy to remove fastener for the battery cord. While routing the cable from the light to the battery, the cord moves around a bit and would tap my ear from time to time. At first it freaked me out because I thought some blood sucking insect or animal was trying to get into my ear but luckily it was just the cord flapping in the wind.

The battery is small and light enough to have in a jersey pocket and pretty much disappears in a hydration pack. The battery can also be strapped to your frame with the included velcro strap. There are slots on the battery body the strap can thread through and secure the battery to your frame.

The light has a bar mount built into it and a helmet mount is included. The helmet mount uses a velcro strap that you weave through your helmet vents to secure. The Seca light then uses the built in bar mount to strap to the helmet mount. When putting the mount on your helmet, it can be a little frustrating, depending on the location of the vents on your helmet…before your first time riding with the Seca, it would be easier to test your setup well before your ride so you will not be stuck in the dark finagling with the strap.

The one thing I feel could be improved would be the on/off button on the light. It is sleek and looks nice but difficult to feel the button with full finger (not insulated) mountain bike gloves on. A slight indentation or other affordance would be nice.

The light has three different levels of beams and also a blinking mode. It can also be put into race mode if you hold the button down for two seconds (when the light is off….not when it is on). Race mode allows you to switch between the high beam and low beam setting and omitting the medium beam and blink modes. I prefer the race mode since when climbing I use the lowest beam setting and high for the descents. It would be nice if it had an option to stay in race mode instead of having to do the button hold every time you powered the light on.

If you are looking for a super bright light to ride with check out the Seca 1700 or one of the newer Seca 2000.

Super Bright!

Pricey, but bright

  • Familiarity: I've used it several times

I've got one of these as a bar light and another one as a helmet light. The combination is BRIGHT... felt I could go just as fast as I do on a daytime ride. The mounts are better than the Niterider MiNewts I had previously - particularly the helmet mount and the battery attachment. The cords are long - I routed the cord for my helmet light down to the back pocket of my jersey easily. Easy to change brightness on the fly - the buttons are large and easily to press with a glove. Overall I love them, though price is up there.
