Light & Motion Seca 750 Light $0.00
750 lumens is a lot of light coming from a bicycle. It's not the 1700 lumens that you get from some lights or from the landing lights on commercial airliners, but 750 lumens is a lot of light nevertheless. For instance, it's plenty adequate for an evening of ripping singletrack. Of course, the icing on the cake is the 750's ultra-light weight.
Something that often escapes conversations about light power is light quality. Different lights can emit light throughout a portion of the color spectrum–sometimes too blue, green-hazed, or yellowish. In practical human terms, our eyes are built for natural light, and Light & Motion strives to make equipment that produces light as closely matched as possible to the color of natural mid-day sunlight. Light & Motion relies on powerful Cree XPG emitters for their inherently pure white light and super-efficient operation.
All of this power and light quality would be lost without a well crafted reflector to shape the beam. For the Seca 750, Light & Motion's bi-conic reflector creates a broader center spot that shoots straight down the trail, allowing you to see what's coming, even at speed. This broader center spot transitions softly into very even fill light that lets you see the wooly stuff at the edge of the trail and all of the roots and rocks below your front tire as well. You won't be spotlighting raccoons up in the trees either. The reflector shapes the light and directs it all where you want and need it. For those commuting or using this light on the road, you can be sure that you will be seen.
The Seca 750 comes with a tool-free handlebar mount that will work on just about any bar diameter or shape as well as on the included helmet mount. The mounting arrangement has been redesigned to rotate the lamp forward on the bars. Perhaps the greatest benefit of this new shape is that the light will sit further towards the front of your head when you're using the helmet mount.
The Seca 750 comes with their 2-cell lithium-ion battery pack, and will run on full power for 2 hours. It will run it on medium for 4 hours, and the low setting will stretch out to a 8 hours of run-time. When the battery is waning, the included Mini-L Smart Charger will get it fully recharged in 2.5 hours. Two operational modes allow flexibility. Cruise mode allows you to cycle through high, medium, low, and flash for safety. Race mode is more streamlined; a two second push to turn it on will allow you to have high and low only. Use low for climbing and high for descending and hammering down.
The Light & Motion Seca 750 comes with a 50in power cord that allows you the freedom to put the battery in a variety of locations. With the handlebar mount, hang it on the top or down tube. Use it on your helmet and stuff the battery in a jersey pocket or a backpack.

Mediocre Light for Nighttime Singletrack
- Familiarity: I've used it several times
I've used this for 5 group night rides and would advise anyone riding for 1.5 hrs or more to get a light with a longer lasting battery. Contrary to what the description says in the first paragraph: "For instance, it's plenty adequate for an evening of ripping singletrack." Its NOT adequate for more than +/-1 hour of ripping singletrack in a group ride situation. Strava showed 1':55" of elapsed time and 1:31 of moving time. The light sputtered out before the ride was done. I think its typical for mountain bike rides to have breaks and regroups, so one would expect a 1.5 hr ride to have a longer total elapsed time. The problem is you really need the full power/ 750 lumens for the whole ride and this does not have the battery power to sustain that.
