3 LED in the Eyc T senso , 2 flat ones are day running & stand light, the focused single point LED comes on @ night, in motion.

kickstart

If the light is on in any mode, the side marker lights are on.

that would be interesting. I once owned the 40 lux iq fly which I thought was very bright. when the cyo came out I upgraded it to the 60 lux cyo. not much brighter really hardly noticeable. those 2 lights shared the same reflector. then once again an upgrade to the 80 lux cyo premium which showed a lot of improvement due to the reflector re-design to the wider beam, not really brighter, or maybe just slightly, but just a larger patch of lit road vs the old cyo. I'm sure the 100 lux light will show a little improvement, but I'm trying decide if that justifies spending $150.00 on another light just for a modest improvement, seeing there was not much improvement between the fly & old cyo. it's all about the beam design really..... all pics are hard to judge by as some show vastly different beam shapes & brightness...

people's opinions vary also as one poster here said he didn't like the iq-x beam & want's to go back to the luxos rated at a lower lux....

saturnsc2

same here with the cyo premium, but they don't completely shut down just dim & get bright as required.... 4 led's are daytime running. 2 of them are the standlight & 1 is the main beam.

I really like the Luxos beam. I messed up the bike it was on and so I haven't been using it. And they went through some growing pains with that light, so I haven't been motivated to get it on another bike. The problem with brighter lights is that your eyes have to adjust to contrast anyway, so a big difference in lux may not translate to something you will notice. The thing that I really noticed with the Luxos was that going around corners at speed was never an issue. With a lot of other lights I end up changing my line so I can see around the corner.

I just bought the Premium from a friend, and I wanted to use a B&M taillight on the bike it's now on, so it was natural to retire the supernova that was on there. The IQ-X is going on my randonneuring bike, where it's nice to have a lot of light

I like the cyo & luxos beam photos on the b&m site the best, but I know that in real life that's a different story...

how are the beams of the supernova? I have heard they are pretty narrow. it looks that way on peter white's site...

kickstart

Both the IQ-X, and Cyo work great in all environments, but if I were trying to decide between the two, I would go with the Cyo for an urban environment, and the IQ-x for suburban and country.

The IQ-X is significantly brighter and wider beyond 75' making it much better for the open road, lots of oncoming traffic, and fast descents. The standlight is more focused, and stands out better in the distance.
The Cyo's beam being less bright, and focused in the distance gives a little more peripheral light in sharp turns. It's standlight is more of a floodlight, and is more noticeable up close like for pedestrians in a crosswalk.

I suspect the facets contribute to artifacts and bright spots within the field of illumination. With each new iteration of their focusing mirror, the facets have gotten less sharply defined.

I rarely roll at less than 8 mph. I consider that to be quite slow. When I'm going less than 8 mph, I expect I'll be able to see by any light and often with no light at all. So this sounds good to me.

unterhausen

the supernova beams are really second-rate. The only thing they have over other brands is their hardware and housings, which was why I was using one on my gravel bike.

yeah, that's why I mentioned it. I'm sure it's easier to cover a space with facets. Getting such an amazing beam with a totally smooth reflector is impressive.

fietsbob

B&M the bright LED faces down.. Engineering that, is how they shaped the beam & cut off .


A light source in the center of the reflector is akin to a flashlight..

At least Mag lights pull the bulb in and out changing the beam from wider to narrower.

saturnsc2

ya the supernove beams pictured on peter white's site look unfocused & narrow, bright, but unfocused. the b&m beams are focused where ya need them most.

to the people who bought the iq-x light how is that plastic band mount on the light itself? is it pretty strong? will it fit any mount bracket? I have an old steel light mount on my bike for many years. so far it held the iq-fly, cyo, & cyo premium in addition to other various old dynamo bulb type lights. just wondering if the iq-x mount is like a different size where it clamps into the bike bracket mount, or will it just mount like any other light....

znomit

I'm using my steel Cyo mount. Much more stable than the one included with the IQ-X, though no cable management and its not adjustable. Same bolt fits both.

savvas

Confusing units of measurement here? The upgrade is supposedly to 100 Lux - not 100 lumens. I've seen mention somewhere the the IQ-X could be in the order of 400-500 lumens.

Presuming you meant to refer to Lux, you could be right of course...

Sam.

kickstart

Yes, 100 Lux, and about as bright as a typical 500 lumen bicycle light, but with greater range.

kickstart

Seems plenty strong, and I'm using an alternate B&M mount. If your mount works with the other B&M lights, there should be no reason it won't work with the IQ-X as they're all basically the same.

southpawboston

It mounts the same way. It has the same 10mm wide base with drilling for an M6 bolt, same as almost all if not all previous B&M lights. But it differs in that the base is not hard-cast into the housing like their older lights. It's part of a separate ring, and it's split at the base so you can remove it and install it facing up (for a hanging light) or facing down (conventional installation). The ring locks to the light in place when the split base is pinched together between the bracket arms.

Here it is installed on a little fender widget of my own design (I sell them through my web store, velolumino.com).

saturnsc2

does that silver color have a clear coat over it or is the light bare aluminum?

unterhausen

Finally took mine out of the package over the weekend. The finish looks like brushed aluminum to me, no anodizing. I could be wrong.

saturnsc2

I thought I seen an online description as them saying it was anodized...

unterhausen

the black one is obviously anodized. Looking at mine again, the silver one is probably anodized too. The surface isn't brushed, it's turned.

Somebody mentioned on the randonneuring email list that their IQ-X died. Hopefully that is pretty rare.

saturnsc2

could be a just a defect not unheard of. oh well they should replace it as it's new....
there are some experimental dynamos out there & those could damage the light. you going to post some beam shots when installed? it's a cool looking light. I heard these are actually pretty small lights. smaller than the cyo?

southpawboston

What's the difference between brushed and turned? I get that it's turned on a CNC mill and the cutting blade produces the fine lines, but isn't there a final brushing/deburring step on the mill as well?

kickstart

The Cyo is approximately 2 1/2" long, and 2" in diameter not including the DRL housing. The IQ-X is slightly smaller at approximately 2 1/4" long, and 1 3/4" in diameter.
