Looks like being around the 100 euro mark in the German shops.

Danneaux:
Thanks, Rual!

Best,

Danneaux:
They've done a nice job of spreading out the light, but the beamshots make it appear there might be some "holes" where the light is not so even. I'd sure like to see one in person or wait till some reviews come in. I think they're definitely going in the right direction, but I'm not sure if reality will match the beamshots. I do like the appearance of the mount and find the housing pleasing to my eyes.

I think where I have just managed to buy a Cyo Deluxe on sale and it gives such a nice, even wide spread, I'll stick with it for now until the next generation or the one after (meaning about 18 months). Sometimes the difference between leading edge and bleeding edge is very fine.

As Andre has noted, B&M seems to come up with new models continuously, and the newer models don't always prove out against their predecessors, so I'll hold tight for a couple more years with the Deluxe, which so far is head and shoulders above my second-generation IQ Cyo R for sheer brightness, width, and most of all, getting rid of a hotspot I found irritating beyond all measure on 400km runs, which take me through the night. When I leave at 3:15am and return about that same time 24 hours later, then I can be pretty well assured I will be riding in 12-13 hours of darkness (depending on time of year), and that's a long time to ponder a hotspot which makes the rest of the spill beam look dim and contributes a lot to eye and rider fatigue.

I'll sure be watching the reviews on these from rando riders. Thanks, Rual, for the heads-up! It looks extremely promising.

Best,

Dan.

Andre Jute:
Thanks Rual. That lamp looks like the business, at last. I might even be tempted to give up my first series Cyo for the either this edition of the IQ X or the third version of it. (BUMM sometimes lucks out with the first edition of a lamp, as they did with the Cyo. They have a pretty grim history of launching retrograde second editions, and then making a step advance in the third or fourth edition, vide the Cyo again.)

I like the French ultramarine on-indication (the blue ring), the ability to use a reflector (presumably supplied in the price) without cutting down the lumens, the sideways light slits (if they're big enough to be seen by motorists at T-junctions), the tall, adjustable mounting arm (I hope it is glass-filled, because the hitherto best tall mount by BUMM appears to depend for its rocksolid performance on being glass-filled nylon), the fact that there is light directly in front of the bike and to the sides without having to take a cut in output. In fact, this lamp appears to answer most of my criticisms of BUMM lamps in the past.

However, the light output, while plentiful, seems to have some holes in it, which could be disturbing to those of you who ride many hours through the night, especially when you're tired and could mistake a glimpsed shadow for an obstruction and swerve, perhaps into danger. I'm almost never on the bike for more than an hour at a time at night...

I'd like to see consumer-shot beam photos before I splash out, but this lamp, or one of its immediate successors, could bring me back into the BUMM family.
