Gadget review: ViewPoint Gen3 Headlight
Commuting by bicycle at this time of the year means riding in the dark. My
primary lighting until how has been a PlanetBike DualSpot which is good enough as a "be seen" light in its flashing mode. Its steady modes, I've found, however, are not great for lighting up the road ahead. Lately, however, the roads have been torn up by lots of construction, and it's become more important for me to ride carefully, lest I drop a wheel somewhere nasty, and crash during the evening rush. It was time to get a new light. Most battery-lighting solutions are either feeble but compact and affordable (like my DualSpot) or as dazzlingly bright as they are stupendously expensive. Into this comes the ViewPoint Gen3 headlight, which I picked up from my local shop--which happens to be a Performance shop, about which more some other time. For the princely sum of 39 U.S. dollars, here was a LED headlight claiming to be brighter than a 10-watt halogen lamp and run 9 hours on a set 4 AA batteries. The bulb wouldn't ever need replacing, either, being a LED. I was intrigued, and picked one up. The lamp housing is about the size of a typical single-halogen headlamp, and it sits over the flat battery pack which holds 4 AA batteries (not included, of course). Bizarrely, there is a wire leading from the battery pack which must be plugged into the appropriate place on the lamp. I mention this because the battery pack and the lamp are actually inseperable, so I can't work out why on earth one would ever need to disconnect the power cord. Technically, the mounting bracket and the lamp are two pieces, but, since the bracket mounts with a quick cam similar to my DualSpot's, it is possible to keep the unit together. The quick cam clamps securely to my Jamis Aurora's drop bars, although I had to loosen it quite a bit. I loosened it too much and ended up accidentally taking the cam clean off. the threads are very fine, and I was frantically trying to get things back together. Let that be a less to you, kiddies--never test gear for the first time in a dark Metro parking lot! On the road, with the lamp on at its brightest setting, I was actually able to spot irregularities in the pavement ahead quite well. I've never ridden with a 10-watt halogen, but I can say for certain that the LED in this thing was at least an order of magnitude brighter than my previous light. While it threw a rather diffuse beam, the difference I could immediately notice was that I could see *and* be seen. Quite confidence-inspiring in early-evening, crowded suburban traffic. In fact, the light it threw out reminded me of the last decent set of lights I had on a bike--a horrid Union plastic bottle generator dynamo lightset. My new light actually threw off as much light as that whirring contraption did which has immediately set me to thinking about getting a dynamo and a LED headlamp sometime in the future. Why not get one now, you ask? Because I needed a light *now* for commuting, and no shops in my area stock dynamos, that's why. Overall: Money well-spent. This "high-power emitter" stuff is not a gimmick, at least not to me. -Luigi |

The only LED headlight I've seen that will work with a dynamo is a rather expensive ($120) Busch & Muller, high price is apparently due to the rectifier circuitry needed to work with a dynamo. The halogen bulb B & M Lumotecs work extremely well, and you can keep the Viewpoint Gen3 as a backup. -- mark |

That light looks like a re-branded version of the NiteHawk Emitter. It's an OK light, pretty comparable to a good 2.5W halogen light, like the Cateye MicroII. The battery life seems much better (I've had one for a year) than the halogens, with the advantage that, as the batteries run down, the light stays white, just gets gradually dimmer, so the usable battery life is excellent. The Cateye has been selling for as little as $10 though. |

The Cateye has been selling for as little as $10 though. I agree with perhaps ten thousand other cyclists that the Cateye Micro II is a very good little light, perhaps better than all of its flashlight-battery halogen competitors. In my experience, it's fine for at least 15 mph riding. Part of the reason is the excellent optics. The beam is well controlled, putting the light where it's needed. Being the resident optics freak, I wonder: Can the LED from the Specialized / NiteHawk be fitted into the reflector head of the Cateye - or, for that matter, the head of a generator headlight? If such a scheme worked, it would improve the "diffuse beam" that I see with every LED light I've inspected. Recently, Andreas Ohler (IIRC) pointed to a German website, in which a guy detailed how he fitted a couple 3 Watt super-LEDs into a generator headlight shell. The operation was greatly complicated by the need for a large heat sink. Is there a big heat sink or electronic package that must sit attached to the Nite Hawk LED? - Frank Krygowski |

I've had one of these for a year or so (and it's been much discussed in the group, usually referred to as the "Emitter," which is what NiteHawk, the manufacturer, calls it). I use it as an ancillary/backup. It's not bright enough by itself for my commute, which takes me through some dark areas, although it's much better than nothing. I also have a Light & Motion Vega, which is a 3-watt Luxeon LED (which L&M pushes to about 3.8); the Emitter is a 1-watt Luxeon. The Emitter is vastly less bright than the Vega, and the Vega in turn is about on par with a 12-watt halogen I compared it with. I use the Vega and the Emitter together. The Emitter lights the pavement directly in front of me; aimed up, the Vega provides enough brightness to see through turns and over to the sides. I find all this a worthwhile upgrade from bottle-battery lights with their extra weight and loss of a bottle cage. However, I've been recommending the Emitter heavily to co-workers who are suddenly bike commuting in the face of Philadelphia's transit strike. It's a lot of light for the money, it's easy to manage, and within the city it's more than sufficient. RichC |

In fact, the most remarkable thing about it is how cool it runs. It actually puts out enough light to please me...enough to make me wish I had a dynamo version mounted on my fork crown. Time to start saving my pennies for a call to Mr. P. White... -Luigi |

snip. I mention this because the battery pack and the lamp are actually inseperable, so I can't work out why on earth one would ever need to disconnect the power cord. They do it for production reasons. Nighthawk sells the same headlamp with a different battery pack for a camping-style headlamp. They only have to make the cord longer and change the mounting for the battery pack. snip I agree this light is sufficiently bright for city riding. Twice I've been flashed by cars who see to think I have my brights on. That's how I know it's misadjusted . On a dark path with no moonlight I think two of these lights would be sufficient. But then if my commute was that dark, I'd probably be investing in an HID lamp. -C |

Sounds like lumens are being wasted by bad optics. On a dark path with no moonlight I think two of these lights would be sufficient. But then if my commute was that dark, I'd probably be investing in an HID lamp. I find a dark path with no moonlight to be no particular problem. My eyes adapt to the darkness, and my 3 watt generator set lets me see well. - Frank Krygowski |

If you aim it at the point in the road by which you'd be able to stop going 18mph, it's not very bright. Of course, I realize that I could be wrong as I really don't have much to compare to as you do...these lights are pretty pricey....so it's hard to gather first-hand data and gleaming what someone else means isn't as easy as one would hope, either. For example, I'd say the Emitter's light is bright white, why I've heard others say it is bluer than some other lights. That was me, and I have an emitter and a Vega right next to each other. The Emitter is bluer. Figuring this light thing out is a pain in the butt, if you ask me. And expensive, too. Buy from a place that will give you no-questions-asked refunds. This includes any of the big mail-order places. RichC |
