The Supernova E3 Triple 2 light is a superbly engineered dynamo headlight, designed and manufactured in Germany. Supernova claim the E3 Triple 2 to be the brightest dynamo light available anywhere, and will outshine many high-end battery lights.
It’s primarily a light designed for racing and bikepacking: it has a broad light output that is closer to a floodlight than a focused beam, and so doesn’t give the ‘tunnel’ effect of some of the powerful battery-powered lights. This means it’s great for illuminating branches, etc. above you and to the sides. If you are used to a sharper more obvious ‘beam’ the floodlight style light may seem a little soft at first, but the output is immense and ample for hacking down fast trails at night. It’s not so suitable in traffic due to its large output (you’ll dazzle oncoming traffic), so riding with the light dipped downwards is the way to go when on the road.
At slower speeds any dynamo light will become less bright, but the Supernova keeps outputting a very usable light right down to crawl pace on steep climbs. At super slow speeds you may see a pulse effect (i.e. when you are out of the saddle because that’s the only way (!), your cadence will become ‘bumpy’ as push the cranks through their stroke, and this translates to the light output).
Pair it with a Supernova or Shutter Precision dynamo hub and you have a winning lighting solution for your nocturnal bicycle adventures!
