Anyone heard of this Dynamo LED light?

[Super Dave]

I would love to get a dynamo powered light that is using the newer generation of LEDs.

This sounds very interesting.

I was wondering if anyone has heard of it?

Are there any other options out there?

Thanks,
Dave

No one I think - and almost nobody will be able to test this light... Their lights costs fortune !

If you are looking for a new dynamo powered light based on Cree XR-e or Luxeon Rebel – look for Busch & Müller KG -> LUMOTEC IQ Fly.

Hmm... I disagree. There are several other lights out there that costs more. 142 euros is pretty much on par with other high-end lights.

I sent an email to the US contact for Supernova and this is what they said about the light...

"The E3 will be ready for shipment next week.
It uses a Seoul P4 (best bin) - the brightest LED in the world.
With 60 Lux (or ca. 200 Lumens) , by far the brightest dynamo-
powered light out there."

​

I have been out of the loop. Does that sound like a good bulb and bright light? I'm curious to hear your thoughts. I'll probably buy one if it sounds good.

Thanks,
Dave

Szemhazai,

Thanks for the info on the Lumotec IQ Fly. How do you think it would compare in brightness to the Supernova?

I'm glad there is progress being made for generator hub lighting.

Thanks,
Dave

Here's a recent review of the IQ Fly.

I talked to an engineer at Supernova this afternoon. The US # defaults to the German HQ. They expect to be shipping the E3's by the end of next week. They can be ordered direct from Germany, for ~205$US. The Emitter is in fact an SSC p4, and the output should be 210-230 lm. Allowing for emitter efficiency and optical losses, this seems about right.
The light is designed around a 6v, 3w dynohub. Coincidentally, they are located ~100mi from Schmidt Maschinenbrau (SON), and the light was developed with that hub in mind.

I've seen quite a few B&M lights, and not been impressed. I have sent more than a couple of the OE versions back to manufacturers. Broken cases, unreliable mountings, and simple malfunctions.
Their site doesn't give outputs in lm, but they claim 40 lux for the IQ fly, as opposed to 60 for the E3. The IQ fly may be an improvement over the Lumotecs and Ovals, but the pix don't look like it.

The Emitter is in fact an SSC p4, and the output should be 210-230 lm. Allowing for emitter efficiency and optical losses, this seems about right.

Allowing driver efficiency and dynamo output, keep in mind that SSC led needs over 1A for this kind of output with driver 85% effi 1,15A 3,8V = 4,37W it means => 6V at 0,73A or with current lock 0,58A and 7,5V.

What speed you need to maintain to get this kind of output ?
