Thanks @cyccommute i think that the mounts you listed are great. I tend to switch back and forth between helmets depending on the temps and don't have to have to switch the light as well. I have thought about a cygolite Dart 350. i know a guy who put one that size on his helmet. It looked like it would mount pretty easy and doesn't weigh much.

Whatever light you use, please don't point it up into the faces of fellow riders passing you in the opposite direction...

I bike commute to work every day and with the days getting shorter, I wanted to see if anyone had a recommendation for a good bike light. I usually leave work at 7 or 8pm, so it's pitch black outside from October - February. Luckily I'm in Chicago so there are plenty of street lights, but these don't make me any more visible to cars (bike lanes just mean more space for them to attempt u turns) and there's tons of construction so I'd love to see the road more clearly to avoid bumpy damaged spots. I have been looking at NiteRider Lumina, but I have no experience in buying lights and want to make the best purchase. A good mounting system, bright wide beam, and decent battery life are my main focuses. Easy mounting and unmounting would be a plus, because I ride two different bikes depending on if it's snowing/rainy or clear outside.
I use 2 Cycle Torch "night owl" headlights, which each came with a rear light. The advantage to Cycle Torch lights is that they are charged by USB port on computers (or your USB-supporting surge protector).

I never understood how non-standard batteries are an "advantage". To me, having to take the light (or whatever device) out of service to charge the battery is a major disadvantage. That's why I find, for example, the spoke-mounted MonkeyLights to be at an advantage. It takes standard AAs. I run all NiMH rechargeables, so when the batteries are getting weak, I swap in a charged up set and charge the weak set. I even have several little two-up AA/AAA USB chargers, keep one in each desk drawer and each pannier/bag/pack/etc, so I can charge two at a time almost anywhere. In a pinch, I can go to any store and get a set of Alkalines.

18640 batteries (commonly used in powerful LED flashlights) are not hard to find online (although I've never seen them in a brick&mortar store), and hold many many more mAh. The flashlight I use on my bike requires one 18650, I keep two in rotation, as you describe. For my usage, I charge at most weekly in the winter. My light also can take three AAAs next to each other in a triangle, if it comes to that. The light had a plastic adapter shell to hold them, I've never tried to use it, and it is surely long lost now.
Some LED lights take CR150 batteries, which are also commonly used in cameras, and I have found them in drug stores before.

Now this ^^^^^^ kind of flexibilty makes sense, especially if the device itself doesn't have to be used as the charger. Def. worth looking into.

I guess I never had a problem popping the light off my bike to plug it into the work computer. I don't see how that's any better or worse than popping it off the bike to change a battery, be it rechargeable or not.
My headlight has an 18650 in it but it hasn't needed replacement yet.

I really liked my Lezyne megadrive. Great design, very bright at 1200 lumen, but it would just not fit in my cockpit with hydraulic brake cables etc. And their newer designs do not have the dame features (field replaceable lithium batteries and clever mechanism of waterproofing of the battery. They are still good I am sure,.
No I use a garmin varia Ut800. At 800 lumen it is not as bright as the Lezyne. Also the battery has a limited duration and is not field replaceable - but good enough for my 30 mi RT commute ( a good part on unlit paths and through woods in Chicagoland). Most important, It has a go pro mount and mounts under my garmin 520 mount. An added feature is it can be controlled by the 520 and has a number of different modes (including based on speed) and it has a good flashing mode for visibility that lasts a long time. The light can be taken off or attached easily with just a twist of the mounting ring (which you can see in the attached photo - the knurled ring above the light).. I can also mount it in my k-edge garmin mount on my road bike. You can mount it on any bar accessory that has the correct orientation go pro undermount.
Not sure if you are looking for anything like this, but thought I'd trow it in.

With a removable battery, you can pop in a fresh set and be up and running again with no downtime while the other batteries charge. If you've ever left a light on all day (or overnight) and come out to a light with flat batteries, you appreciate the option to swap batteries and go.

My local Fry's brick&mortar stocks 'em. My Fenix BC21R bike headlamp (with its shaped beam) uses one.

OK, that's not surprising, but if you're out riding who knows where and desperate for batteries, you're much more likely to come across a convenience, drug, or grocery store.

My Fenix BC21R will accept 2X CR123A in place of the 1X 18650. I see CR123A in the ubiquitous CVS corner drug stores in my area. Since I carry a spare charged 3400mAh Panasonic 18650, it's just a theoretical issue for me. YMMV.

Is that a standard thing, that 2x CR123A can take the place of 1X 18650? I assume the size is right, so they can sneak right in like a tower of minions in a trench coat sneaking into the movies with one ticket. But does the electronics work out right (volts? watts? amps? ohms? currents? resistances? other electric words?)

^^^^ Current, power, resistance are functions of the LOAD. Voltage would vary with how the batteries are arranged. Your old high school physics info still applies. If the tw CR123As are stacked in series, the voltage would be the sum of the voltages of the two batteries. An 18650 is 3.7V; I'd have to look up a CR123A.

If you work sitting at a computer or near a power outlet*, a USB recharged battery light would be practical as long as you trip does not exceed the battery run time
and if close get 2..
*Plug in USB power converter like your Phone Charger?

If 2 CR123As are filling the space of 1 18650, then they would be stacked in series (like a tower of minions in a trench coat (why does the internet have no picture like this? I could have sworn they did this gag in at least one of the Despicable Me movies!))
the webz does say it's in there, but not giving me pictures...

The LOAD or light in this case, regulates the power. A good load incorporates a good regulator or power converter for safe operation. A cheap load produces grief.
I like the 18650 cell. Long life and rechargeable. The high current capability of the 18650 must be respected though. Throw a fully charged cell into your pocket with keys and you'll have something like this ..,

A safe way to carry spare 18650s is found at walmart in the camping section

i have two lights front and two rear. Last week on my ride in my rechargeable Cyglolite had died. I forgot to charge after a week of riding last week. luckily I had my charged 5000mAh battery pack running my Orphos Flare PRo Red. i might drop one of the lights/ batteries when it is warmer but in the dark ages of winter i like having the extra light and redundancy.

^^^^^ Yeah, 6V in series vs. 3.7. From what I know of LEDs, they tolerate a wide voltage range, but indeed, won't last as long at higher voltage. Most any other device would probably not be as forgiving; an old-school tungsten bulb, for example, would probably burn out in seconds or minutes at nearly twice the rated voltage.
I'd be more tempted to run two very weak CR123As, or one good one and one dead one (as a conductor), in such a situation.
Turns out I have a slew of 18650s, from an abandoned project to rebuild a Ryobi 18V battery pack. I just ordered a light like the one depicted by @RubeRad , with a charger and bracket.

^^^^^ Eek, good info there. That would disincline me to run CR123As in anything.
