I have a couple as my main night riding lights.
One points down near to the front of the bike and the other is set to shine as far down the road as possible. I use both lights mainly on the "low" setting, only using the "high" beam on the distance light when there's nothing coming the other way. If I don't dip it, I get flashed by oncoming cars. I've thought about a trying to molish a remote dip-switch but I keep chickening out in case I bugger it up
The beam is the same shape as the standard IQ with the "black hole" in front of the wheel. That's part of the reason that I run two.
It's possible to run two lights off one battery although I've got two. I've never had an issue with battery life and it gives a couple of hours (seemingly) of light when the battery is run down. The first sign is that "high" beam can't be selected and the LEDs on the top of the unit flash "red-red" instead of "red-green" when it's on "low" and "green-green" on "high".
The Speed is a little brighter than the IQ.
Waterproofing seems to be excellent; mine survived the "Mancunian" weather on this year's Manchester-Morecambe FNRttC as well as the reccy ride which was nearly as wet.
The fitting is quite clever. There's a strap which loops around the bars and then back through an over centre clamp which locks it. With the strap pulled tight I've not had any problems with movement even over big bumps.
The strap is long enough for OS bars but I've mounted my lights on a Topeak BarXtender so that I can transfer them quickly between bikes.

B&M's customer service is excellent as well. I had a lead start to give problems with intermittent contact when the lights were about 18 months old. I e-mailed and asked to buy a replacement and they sent one FOC.
I like these lights.
