New Bike Specific Light - 128 lumens - 6 hours - $76!
This new light looks quite promising. It's bright at 128 lumens, takes AA batteries, and has a long runtime of 6 hours and a battery guage. Has anyone heard of this before?

EDIT: It's a Dosun M1 Bike Light.

128 Lumen is not really all that bright compared to the new power LED's. Thats less than a Cree XR-E operating at the lowest power setting of 10% when using a standard 5-mode driver circuit. My dynamo powered DIY LED headlight produces 500 Lumen at 7 MPH. You would do much better with a Cree or SSC flashlight from DX. They have flashlights with the new SSC P7 emitter producing 900 Lumen for ~$50.

they need a better video. Looks kinda big...I wonder what kind of mount they have coming with it.

128 lumens for 6 hours is good for a city commuter light.

Yeah, its significantly brighter than most bike lights out on the street, and looks like a useful beam pattern. Runtime means you'll change batteries once a week rather than every day.
I like it.

More lumens don't necessarily make a better bike light. Effective power management, bi-level beam pattern and cut-off shielding combined with a decent lighting level makes this a pretty special combination. How many DIY, chicken-frying-lumen output headlights have these features?

Two SSC P4 U-BIN Z-power LED's under Fraen optics. 10 degree narrow left and 15X30 elliptical right. Bridge rectifier and 1,000uF capacitor is also located in the housing. No batteries required as it's driven by the dynamo.

The background music in the video will be stuck in my head for the rest of the day now...
I like the concept, but two things are keeping me from buying it. The lack of information on the mount, and the fact that it is 128 lumens. If it was a tad brighter, say in the 200 lumen range, I'd be all over it to replace my fenix lights. I really want something self contained, with good brightness, a solid beam pattern for biking, and good runtime, say in the 3 hour range. This is close, but not quite there.
That said, I'll probably grab one next week and see how tinker friendly this light is.

I'm not sure who this light is designed for. The Planet Bike 1W Blaze puts out as much light, is $30 cheaper, is smaller and has a 7 hr run time on AA batteries. If they are aim the light towards the crowd that needs longer run times, the light is too weak.
'Tis a silly light.

The beam in the video does not seem too bad for what is basically a cute little flashlight. I'd aim it a little higher so cars could see it better but then the narrow patch on the road would make it harder to see road hazards. I'll stay with my DIY system even though I need a battery that could start a small motorcycle.

There is something funky about the beam pattern of the light in the video. Unless there is another light mounted somewhere on the bike, the pool of light right below the wheel is absolutely useless. Illuminating where the wheel is gives you no information about what your wheel might be falling into. By the time you could see a hazard with a pool of light directly in front of the wheel, it's too late.

Anyway, I was only responding to another comment about how DIY lighting could never be as good as commercially available lighting which is not true. In all reality DIY LED lighting is far ahead of manufacturers because of the extremely rapid pace of ever brighter LED's. It takes a lot of development time for a manufacturer to bring a new product to market. Currently Power LED's are in an extremely rapid development phase. An example is the jump from the Cree XR-E at 220 Lumen output (without optics) to the SSC P7 900 lumen (also without optics). The new SSC P7 with optics is so bright at full power it exceeds DOT limits for automotive headlight use.

I'll agree that some light spill is needed but the (poor quality) video shows something else entirely. It looks like part of the beam is aimed directly at the front wheel. There also doesn't appear to be any light from there to where the main beam hits the ground. Of course, I'm used to the pavement smoking while I ride

There are new people showing up all the time on this fo and most do not search the fo for prior posts. This would exclude them not only from my information but others as well. If I and others only posted once the fo would soon die from lack of use. Just because others can't DIY equipment should not limit information to those that can. I've had many private messages from others wanting more detailed information about my latest light.
I'm also not exaggerating. My dynamo current output is 700mA with two power LED's in series and when used with high efficiency optics 500 Lumen is easily obtained. You can see this from the following graph available from SSC website.
