i just got the lumotec iq fly led light. http://www.bumm.de/docu/nojsmenu-e.htm it's the brightest light i ever saw! much brighter than my 2 lumotec halogen setup! it has h.i.d. blue hued like brightness! the standlight feature is actually even brighter than my old halogens! another great thing is the lights get to full brightness at walking speed, even slow walking speed while i have to go about 7 mph to get full brightness out of a halogen light. guys take my word for it, throw away your halogen light setups & get this new light! it's amazing! i bought 2 of them for both of my bikes & will sell my old b&m halogen lights on ebay!

mmmmmmmm
A massive 40 lumens!!!!! WOW
I can't see myself giving up my triple Cree Q5 light which puts out over 600 lumens just yet.

i think your missing the point. sure you can strap a heavy battery to any bike & have a very bright light, but this is the first generator light that is very bright for it's kind. it throws out plenty of light for any riding situation anywhere, & you don't have to charge a battery. i used to have a h.i.d, light on my bike, but i found it to be overkill. most of the light lit up the parks, shined in car driver's eyes, ect. a lot of wasted light, & i got sick & tired of always having to charge the battery after each ride, & also having the battery die on my longer night rides. with my setup i have a bright light that doesn't run down, & doesn't burn out. a great setup...

No big heavy battery required for my light as it only uses 3W.
Bin R2 Cree xre LED's are now rated at 114 lumens per watt. So while it's great to have a dynamo light that's reliable, something brighter than 40 lumens is required for the riding I do in Sydney. If I was doing randonees i would get a front wheel with a Schmidt hub as a backup light.
The Fly most probably uses a low efficiency Luxeon that you could swap out for a new Cree for about $20. Try opening up and seeing what the LED is.

i never heard of the led you mention. how many amps does it take to drive your light? what kind of battery do you use? i have 2 bikes with hub dynamos & led rear lights, & these fly led lights are sweet! i never seen a brighter dynamo light before. it produces plenty of light & it has a special designed reflector which puts a wide bright beam in front of you & it lights up the road really well in all conditions. i don't know what kind of led it uses but it's very bright. the light's really making a big splash as many people are trying to buy them, but they are not even available everywhere yet...

o.k. wait a minute....you have this all wrong. the led fly is rated at 40 lux not lumens which puts it around 500 lumens which is about as bright as yours with only a 6 volt 3 watt dynamo powering it, not batteries.

You have some more reading to do.
no, the fly only outputs 40 lumens. The only LED that can output 500 through a single lens is a multi-die osram and the fly doesn't use one.

For an interesting read as to how to build a dynamo powered triple LED have a look at http://www.candlepowerforums.com/vb/showthread.php?t=175923

The light I built was a copy of this http://www.candlepowerforums.com/vb/showthread.php?t=142791
I use 4 2600ma 18650 lithium batteries
I also made a single led 220 lumen version which ran from 2 18650 batteries as a helmet light which would last about 6hrs.

well here's the light spec right from the B&M site:
CAD aided reflector and transparent glass cover for optimum light generation - up to 40 lux
when i went on some conversion sites 40 lux is about the same as 500 lumens. go on the b&m site & see the comparsion photos of the new lights. they are really that bright. this light is plllllenty bright, no need for more led's. this light is way brighter than my old double halogen set-up....

You have some incorrect recognition.
"Lumen" is different unit from "lux".
"IQ FLY" illuminates the road 10m ahead at 40lux brightness and the illuminated area is wide enough to use as bicyle light on the public road.
On the other hand, another opinion which claims it outputs so much 500lumens, is not correct too, I think.
Perhaps output is about 100-150lumens.
The reason of 40lux is why it's reflector is well designed to use light of LED without waste and not to blind oncoming drivers.
In another words, it does not radiates much light to the sky like a hand light.
