Supernova E3 Pro first impression
Last night, I finally got my new Supernova E3 Pro headlight installed. I received this, along with the new Schmidt Dynohub, a few months ago. I finally got the hub built into a wheel last month, and I finished installing the light yesterday.
The E3 is a dynamo headlight that was designed to be the ultimate dyno light, and the price reflects that fact. If I weren't biking every day (and getting incredibly sick of batteries that need constant recharging), I wouldn't have sprung for it. But I am, and I did.
I opted for the shaped beam version, which has a pattern similar to a car's headlight: a sharp cutoff at the horizon, so as to avoid blinding oncoming drivers, while casting as much light as possible on the road in front of you.
I had actually temporarily installed the light a week or two ago (with a hilarious combination of zip ties, alligator clips and safety wire) and gone for a brief ride along a dark trail. That proved that the beam pattern was pretty useful, and showed that my intended mounting location (right under the handlebar) would work well.
My very first impression of the beam was that it wasn't very bright. That is, it seemed about as bright as my current headlight (a NightRider MiNewt X2). Then I realized that, although it seemed about as bright, the bright area covered something like 5x the area of the MiNewt's bright spot. That means it's a tremendously brighter light, it's just spread out into a much larger, more useful area. There's not much point in spearing a single point in the distance on a bicycle, it's not as if I ever move any faster than 40 MPH at the fastest, and 25 MPH normally.
The beam pattern itself is a bit odd, being quite wide, with "saddlebags" of brightness off to the sides, and not as much right in front. I have a feeling it was designed to be multipurpose, including being useful for offroaders. I'll see if I can get a photo or video of it, and post that here.
The LED or optics give the light a greenish tint, which is a bit displeasing -- when spending this kind of money on an LED light, I expect excellent color, and greenish is not an excellent color. Now that I look at posted pictures of the beam pattern on both Supernova's site, and the Peter White beamshots page, I also have the impression that my beam is a weird shape, and not what I thought I was getting, particularly compared to the beamshot on the Supernova page. I may be talking to Peter White (where I got this light) after tonight's ride.
The light itself, in terms of construction, seems to be well built. The mount is a very pretty machined piece, and the light body suggests high quality. It's fairly heavy, but that's to be expected, since this light includes a lot of aluminum to dissipate heat, as well as a large capacitor to act as a "stand light," keeping the light on for a few minutes after you stop riding (for use at stoplights). The stand light is about half the brightness of when riding, but it's still enough to be seen pretty well. I didn't time it, but my stand light was still glowing 5 or so minutes after a ride. It seems to slope down brightness over time.
Other than the beam pattern, I'm pretty happy with this light. It was spendy, but ideally that's bought me a bright, durable light. I'll post updates as I have them, but I hope to get some photos and possibly video in the next few days.
