  • Some users mention moisture collecting in the housing.
  • Owners complain they can’t disassemble the E3 Pro 2 to repair or clean it.
  • Experts say the E3 Pro 2 must be paired with a Supernova brand taillight.

Bottom line

Supernova’s E3 Pro 2 is designed to be powered by a dynamo hub, so it’s recharged whenever you pedal and never runs out of ‘battery’. It’s lightweight, attractive, and hard-wearing, although some users say moisture accumulated over time. Owners have toured for years with this light. Some folk question Supernova’s specs. One tester told of Supernova sending them out a replacement light as they toured through Azerbaijan!

Supernova E3 Pro 2 Dynamo Front Light

This is about as good as it gets. A well-built, rebuildable unit with a long warranty and near-perfect beam pattern and performance for road use. You’ll never have to worry about where your lights are, or whether they’re charged, ever again.

Supernova E3 Pro 2 Bike Light Review [German]

Although the Supernova E3 Pro 2 doesn’t quite get a very good rating in the test, it’s still a good choice. The “made in Germany” seal alone guarantees quality construction.

My Audax Dynamo Light Setup

When you’re on a big ride at night, you’ve got a lot of hours of darkness and sometimes battery lights won’t last long enough, so I got myself a dynamo. It’s 1 year old, it’s done six to seven thousand miles. I don’t think it’s completely watertight, but it still works.

Dynamo Powered – Supernova E3 Pro 2 Headlight

This is a standard M5 mount which means that you’re actually going to be able to mount this to just about anything and you can adjust the multimount to be able to work with a whole bunch of different setups.

Review: Supernova E3 Pro Dynamo Lights

Super bright wide beam, perfect for bicycle touring. Beautifully made and comes in nice colours! 100% waterproof. We believe that Supernova makes the best dynamo lighting systems around (especially the E3 Pro 2).

Review: Supernova E3 Pro Dynamo Light and Tail Light

Without a doubt, you can get a cheaper hub dynamo light. The Supernova E3 is, however, far superior to my cheaper Busch & Müller light. The Mercedes Benz of lighting options. It is the one to go for if you really mean business.

Supernova E3 Pro Stvzo Version, From 2010, Supposedly 305 Lumen

Excellent construction. No annoying artifacts. Weak illumination of the road at longer distances (25-45 m). Beam diverges too much. Wastes light where you don’t need it. Very weak standlight. Expensive.

LED Dynamo Light Reviews

The Supernova E3 Pro is my favorite. It’s much more expensive than the lights above. It is a thing of beauty, feels solid, and comes with either a handlebar mount or a “multimount”. I like the beam pattern.

Bike Light Shoot-Out

How would the Supernova stack up against Schmidt’s Edelux? Both mark a technological advance from the E6 lights that randonneurs have been using for years. The Edelux is the way to go. It’s lighter, it’s brighter – and it’s watertight.

Headlights for Bikepackers & Ultra-Distance Cyclists

The Supernova is very bright, but I don’t like the narrow beam shape. One downside of using the Supernova front lights is that you can only use their matching taillights.

Headlight Beams

You can see that this beam is very tall, illuminating the road close as well as at a distance. The beam is also very wide.

Exploring Dynamo Light Options

The E3 Pro 2 has a horizontal cut-off. The advantage is twofold: 1) it prevents you from blinding oncoming traffic, and 2) distributes that extra light to the side. It is intended for road use. I have ridden with it and I did not like the beam pattern.

Bicycle Lighting, Mostly Powered via Dynamo, and USB Power From Dynamo

Nice beam, but only for low speed riding (say 20km/h at night, not 30 km/h) as throw is not far. I doubt any claims made by Supernova because of their behavior and nonsense claims about light output of their lamps. I don’t deal with this immoral company.

Headlamps With Cutoff for Dynamo

Good strong light beam to about 25 m. Weak at longer distances, so only good for low speed cycling. Very weak standlight, no automatic on/off, the multimount is good. Expensive. The housing is really what you pay for.

Updates on the Bicycle Lighting Review Pages

2014-02-05: Made a note of why I don’t want to do Supernova reviews. This is just in case it wasn’t clear from the various places where I mention their immoral behaviour (which hasn’t changed up to now).

Front Headlight Upgrade [German]

To date, I’ve never had any problems with the light cone of the E3 Pro 2. But at higher speeds of 25 km/h, an obstacle is in front of you faster than I thought. I would estimate the headlight range to be around 10 to 13 meters.

Wonderful light cone, just mega. A really wonderful-looking lamp. The Supernova E3 Pro 2 is for people on extremely long tours where lights really suffer. If I went for half a year on a world trip, I would maybe grab the Supernova.

Test: Dynamo Bicycle Headlight [German]

Very robust metal housing. E3 Pro 2 has a switch. The E3 Pure 3 is a bit smaller but has no switch, so it’s always on.
