If you're reading this, you didn't end up here by accident. You're here because you're looking for the ultimate handlebar mounted light setup. So allow us to introduce you to the Exposure Six Pack Mk4 - 6 LED Super Light. At the maximum output setting, it puts out around 2000 lumens. That's brighter than the high beams on your car. And despite the unreal light output, the complete setup still comes in under a pound, making the Six Pack the light of choice for 24 hour racers. This means that you'll see the trail like never before. Just watch out for wildlife, because this puppy makes your average deer catching headlights look like a glorified mosquito catcher.

The Six Pack Mk4 makes use of six Cree XPG LEDs, which put out a maximum of 2000 lumens. In case you're wondering, that makes the Six Pack brighter than the headlamps on most cars. Far brighter, actually. At the maximum output settings, it'll run for just over two hours. For situations where output is less important than battery life, you're able to choose lower output settings, which are able to boost the battery life as high as around 36 hours. It affixes to the handlebars using Exposure's excellent quick-release mount, which like the light body, is machined from billet aluminum. Its wedge design holds the light incredibly tight for an unbelievably secure interface. Best of all, the light and mount come in at a claimed weight of 362 grams, or less than a pound for a setup that's likely brighter than the high beams on your buddy's new sports car.

Like all Exposure lights, the Six Pack is built in the UK by dedicated riders. It employs the finest lithium ion batteries available, for the longest possible lifespan. Same goes for the Cree LED's that illuminate the trail. This allows Exposure to offer a lifetime warranty on the LED's, in addition to the two year warranty on the rest of the light. There's a display which shows you both the selected mode, along with a five-step battery gauge, which take 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 in order 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 an ideal 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 your home turf.

The Exposure Six Pack Mk4 - Six LED Super Light ships with a quick-release handlebar mount and a Smart Charger. It has a 112mm length, a 54mm back diameter, and a 59mm head diameter.

Turns the night to day.

  • Familiarity: I've put it through the wringer

I have this light on my bars, and a Diablo MK5 on my helmet. This combo is seriously amazing. Well made, no hassles with a battery pack and wires. People trip out when you ride up on them- you have to turn it all the way down, or people thing a train is about to pass them. I love these lights!

Unbelievably bright.

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

I don't own this light. I'm shopping. But I went on a night ride with two people who did have it, and they were each brighter than: the moon; any car I've ever seen... they were about as bright as a police helicopter searchlight. It was nuts.

I had to avoid looking at them completely if I got ahead of them, lest I be blinded & blinking spots for ten minutes. This light appears to turn a night ride into a day ride.
