I raced Exposure's new Six Pack light at the Ex Enduro and it saved my weekend twice

Exposure’s Six Pack MK15 is the brand’s brightest bar-mounted light to date, with the aluminium-bodied unit now casting 6,000 lumens down the trail.

As a part of Exposure’s range update released last week, the new light sports USB-C charging and a variety of new features, including the ability to turn into a power bank.

The price of the Six Pack remains the same as the previous generation at £495 / $540, which is definitely at the sharper end of the market, but does its updated performance and capability justify the price?

I raced the Ex Enduro mult-stage event in Exmoor this weekend, which included three night stages, to get an initial feel for the light.

All the stages were ridden blind, with the event organisers changing them each year to keep racing more even for those from outside the area.

Off the back of riding in Morzine for a week, I needed all the help I could get on my return to UK slop.

The Six Pack saved me in two respects. Firstly, its long-throwing and wide-spreading beam helped me to claw back some seconds on the night stages.

And, a gift that keeps on giving, the power bank came to the rescue by keeping my Garmin and phone charged for the three nights of camping.

Familiar beer-can design

Exposure’s lights are known for their finely crafted finish, with the Six Pack feeling robust and well-built.

The light is made from anodised 6063 aluminium and has six XPL2(W3) LEDs that shine a white beam that's intended to be as broad and far-reaching as possible down the trail ahead.

While the previous version was IP65-rated, Exposure has increased this rating to IP67, meaning it's now completely dust-tight and can survive temporary immersion in water up to one-metre deep for 30 minutes.

This brings it up to date with many of the best mountain bike lights, and should give peace of mind should the heavens open mid-ride.

There are seven modes, which are now easier than ever to navigate, thanks to the new OSD+ display built into the rear of the light, which also helps in switching the light into Power Bank mode.

This enables you to use the 20,000 mAh Li-Ion battery to charge other devices, such as phones and bike computers.

I found this was especially useful at the Ex Enduro, where I used the light to charge my phone after each day of racing – taking roughly 25% of the light's battery with each charge of my iPhone 16 Pro.

Exposure claims a runtime of 2 to 36 hours, depending on the setting, and this light now features the brand’s Reflex 2.0 technology, which automatically dims on fire-road climbs and turns up the brightness on descents to optimise battery life.

One of the biggest improvements to the light comes in the form of the USB-C PD port, which replaces the archaic DC port and cuts the claimed charge time down from 8 hours to 5 hours 22 minutes.

The little rubber flap that protects the port from dust and water ingress feels a little flimsy, and depending on the temperature, can be difficult to manoeuvre into the port.

The light has put on some weight, too, now tipping the scales at a claimed 403g, compared to 386g for the previous model.

The mount has stayed the same, and while it retains the light on your bar securely, closing the clasp when initially mounting it to the handlebar is tricky and leaves you wondering if there's no better way.

Chasing the light

The light performed very well and gave a great throw of light down the trail.

My first reintroduction to night riding of the year, the Ex Enduro’s three stages were a chaotic mix of grippy loam and spiteful roots, with the climbs made up of fire roads, forest paths and short road sections.

I found the Six Pack cast light over a generous portion of the trail, with the brightness feeling balanced across the beam and no concentrated hot spots at the centre of the beam.

This helped give depth perception when approaching obstacles on the blind trails, and gave me confidence to push into the unknown, knowing it would soon be easily perceived.

The white light cast from the LEDs helps keep your focus, and I found it less fatiguing than other lights I have tested.

While the Six Pack sits like a beer can on the bar, I never once felt its weight or form factor affecting my riding, and even after a heavy crash over the front of the bike, it didn’t restyle my nether regions.

The light stayed rigidly in place on every stage, with no signs of movement in the mount.

When riding up the climbs, the light toned down the brightness, which I assume not only saved some battery power, but also made me feel slightly better for not blinding fellow riders and passing walkers.

I’ve got more to test before I deliver a final verdict on Exposure’s flagship Six Pack MK15, with plenty of evening rides planned to see how it performs away from the race tapes.

For now, the light appears to offer excellent performance with updated features that may have been a long time coming, but are worth the wait.
