The Seca 800 is second in the hierarchy at Light and Motion. In reality it's the light that would be most appropriate for most folks who like to ride at night. If you can't justify the Seca 1400's extra-orbital cost, even for its surface-of-the-sun luminance, then this 800 lumens version will do the job nicely to light your way.

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 and Motion strives to make equipment that produces light as closely matched as possible to the color of natural mid-day sunlight. Light and 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 800, Light and 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 while hammering down the trail. For those commuting or using this light on the road, you can be sure that you will be seen.

It 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 farther towards the front of your head when you are using the helmet mount. Say good bye to snags on unseen grapevines or low hanging branches. The Light and Motion Seca 800 comes with their 3-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 and Motion Seca 800 comes with a 50" 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.

mounting issues

  • Familiarity: I've used it once or twice and have initial impressions

if you're racing and want the option to switch out spare batteries, this makes a lot of sense. I'm just trying to extend my post-work mtb rides until the snow stops me. i figure that the taz 1200 from light and motion will fit the bill.

this light is very powerful and the price was unbeatable, but mounting the battery to my mountain bike (Yeti SB-66) was time consuming and frustrating. it seemed like no matter how tight I got the strap on my top tube or bottom tube, it would still slip. Also annoying is the excess cable length.

overall, a good quality product that seems to be more of a racer's light. for those of us just trying to extend our fall rides an hour or two, i wouldn't recommend this.

I have the light and motion viz 320 plus which is an amazing light combo. i'm excited to buy the taz 1200 to compliment it. after each ride just plug both of them into my computers USB ports for tomorrow's trail time

Thanks for the review James. The best place for that battery is going to be on your seat post. That is your center of gravity and it keeps the battery out of the way. Wrap the cord around the top tube with a little extra for safety at the handlebars for turning. If you have a seatpost dropper the triangle on that yeti would be another good place for the battery.
