You're not going to give up on riding just because the sun set. And whether you're looking to maximize your visibility for commuting, or you're trying to tear up the trails without running into traffic, the Exposure Race Mk8 Light will add some much needed safety to your ride. With a maximum output of 800 lumens, odds are that you'll be the brightest one in your group. Its durable aluminum construction and top quality LEDs mean that you're able to expect years of trouble-free use. And it's weatherproof, so even when it starts coming down, you won't have to worry. Consider it the upgrade you need when night riding becomes a must.
Exposure's Race Mk8 light uses two Cree XPG LEDs, which put out a maximum output of 800 lumens. At the maximum output setting, it'll run for just over two hours. And for situations where output is less important than battery life, you're able to choose lower output settings to boost the battery life to as high as 36 hours. It affixes to the handlebars using Exposure's durable quick-release mount, which like the light body, is machined from billet aluminum. Its wedge design maintains a firm hold on the light for an unbelievably secure interface. Best of all, the light and mount come in at a claimed weight 191 grams, making this downright feathery for the amount of light that it puts out.
Like all Exposure lights, the Race Mk8 is built in the UK by serious riders. It employs the finest lithium-ion batteries available in order to provide the longest possible service life. Same goes for the Cree LEDs that illuminate the trail. This allows Exposure to offer a lifetime warranty on the LEDs, in addition to the two year warranty on the rest of the light. There's a display that shows you both the selected mode, and along with a five-step battery gauge, it takes the guesswork out of operating your light. It's also helpful that the light charges using Exposure's Smart Port Technology, which enables you to piggyback a backup battery to improve upon the already impressive battery life.
Heatsinks are used in conjunction with an ITM (intelligent thermal management) program. It employs an integrated sensor to regulate the light's temperature, reducing voltage when needed. It's used to minimize heat buildup, since excess heat will actually cause the LEDs to dim. The ITM is customizable by the user, allowing you to choose between settings that maximize output, battery life, or to strike a balance of the two. As you'd expect, the body is weatherproof, so it'll make it through a heavy downpour without a hiccup. And like all the Exposure lights we carry, they ship with US chargers and are subject to US-based customer support — unlike Exposure lights sold overseas. In other words, you're not likely to have any issues, but if you do, you'll be taken care of by like-minded cyclists living on home turf.
