With PWR, all 3 lightheads can fit all three batteries, or "PWR Banks". So if you'd like the occasional short burst of 1850 lumens for that once-a-month mtb ride, but don't need the expense of a 10,000mAh battery, you can build your own light with a smaller battery. The lights come pre-packaged (lighthead+battery+mount) or you can buy the parts separately. Of course the other benefits to this interchangeability are the immediately swap of batteries for "infinite charge". Plus the product pipeline - Knog have already designed a speaker, camping lantern and headtorch for release later 2017 which will use the same battery, and in the case of the headtorch, the same lighthead can be used too.
Everyone owns a power bank. Or at least, we've all run out of charge on our phone all too often. And even the most avid cyclist uses their bike light only now and again. Or if daily, only an hour or so a day. And that's just in winter. So having a product that can do more than just that discrete use is going to be useful. For the majority, it will be used for charging your phone. But there are so many unique use cases. A cyclist may need to charge their Garmin whilst on their ride. Or even, ironically, a friend's bike light! GoPro batteries are notoriously thirsty so PWR can charge that too. Whatever needs juice, PWR can power.
Bike lights come with pre-programmed modes. Usually about five. But how many of those five get used. We know from anecdotal evidence that (not all, but) most people use constant high, and one preferred flash pattern. Knog have developed an app that allows the lighthead to be plugged into the computer and programmed. Choose as many or as few modes as you'd like, select flash or constant, and choose the intensity. Maximum output equates to minimum runtime, and max runtime will show you the minimum light output. Importantly, this puts the rider in control and re-frames the "lumen for dollar" race that currently exists in the bike light industry. Now runtime has equal footing as lumen output, as it should do.
The unique "side mount", for the two smaller format lights, slides in from the side and mounts off centre - this allows the position of the light, above or below the headstem, to be central. This means it can fit snugly under the Garmin for a clean aesthetic. It also includes a quick release for safety when not in use, and a tightening thumb-screw to ensure longevity. The large light requires an under-mount due to its weight. But if the rider would prefer the weight of the battery away from the handle bar, there are two options. 1/ "Bar-frame mount" and 2/"Helmet extension": both use extension cable and additional mounting parts. Other mount solutions include whole light helmet mounts and brake boss mount.
As with all Knog products, form and function go hand in hand. The overall look of a PWR bike light is sleek, made from matte black machined aluminium. A battery indicator turns on from human touch to display four blood-red dots representing 25% of battery life. The lightheads marry up with the circumference of the optimum PWR Bank. The PWR Trail (1000 lumens) and PWR Mountain (1850 lumens) require more heat dissipation and so the "gills" required for this are central to their aesthetic. Twist mode operation - a flick of the wrist to twist the lighthead for on-off and mode-skipping means no buttons are required on the body. Plus understated branding all work together for a product the owner is proud to own.
The PWR bike lights range are, well, lights. So the light is the first thing Knog designed. Starting with evidence from various light comparison websites who found the elliptical beam in Knog's Blinder Arc to be more effective on road than circular beams (where light was wasted), we maintained this approach for PWR Road and PWR Trail. So these lights have 3 core LEDs - two for the wide beam, and one spot for intense light straight in front. PWR Trail has an additional nine glowing LEDs in a ring formation for great "be seen" functionality. The PWR Mountain has 5 LEDs providing a massive 1850 lumen "flood" beam, as you need to see rogue branches coming in at eye level as well as boulders at wheel level!
