Pfft - Joerg turns up his nose at any solution that approaches $150.
No, for Joerg it must be;

$150

Minimum 3000lm, probably with flash modes and low and high beam. (Note:
Lux means nothing to him, it's all in the lumens, Man).

Three week battery life on high beam.

Military grade design (Water proof, aerospace temperature spec.,
corrosion resistant, etc.)

Unbreakable mounting boss.

All rounded edges for safe crashing (better if it has a built in airbag).

EM Pulse safe.

Repels mountain lions, motorists, motorcyclists, flying rocks and angry
bees.

Jay, did I miss something?

Yes, it has to be sealed to IP67 standards, at least.

I thought I covered that with "Military grade design (Water proof ..."


Oh, if it could light a fire and make a hot drink, that would be nice.

My night vision has gotten terrible, and I'm easily blinded by on-coming car headlights. I understand wanting more light, particularly when it is raining. Dynos are not for everyone. With that said, the mega-lumen light sledge hammers are annoying on the road, and in flashing mode, unconscionable.

Jay, where are the mega-lumen lights you are referring to? I have seen
lights in the low kilo-lumens, but they top out at about 8000 lumens.

I'm using mega-lumen in the non-technical sense. Same goes with "sledge hammer." And in the words of Potter Stewart, I know them when I see them (and wince). And to be fair, they are usually high lumen lights that are also mis-aimed or in flash-mode, or both.


500lm, from a small light source, focused to a narrowish beam and aimed
at your eyes will be quite blinding. Mega lumens are not needed for a
light to be blinding. It's got more to do with the beam shape and how
it's directed.

The last night ride I did with another club member showed me that aiming one of
those lights "properly" really doesn't cure all its problems. He has a
Nightrider but I'm not sure which model. In any case, when he was behind me, I
could see nothing past his light in my rear view mirror. But when he was beside
me, I could see that the beam was centered on the road perhaps 15 feet ahead
of him.

So even pointed down like that, it had too much upward glare for
my taste.

Yes, it gave a brighter spot on the road than my new Cyo, but it didn't
illuminate as well. The bright spot was small and glaring. I think an
even illumination of one lane is much better.

Agreed 100%! My 2009 Cycgolite Rover II light illuminates a 2 lane road quite nicely and also does that to a decent distance. It has 2 lenses side by side and uses Cygolite's "Cross-fire" system whereby each light bean crosses the other. On high that light has a total of 250 lumens. I can only imagine what a similar "cross-fire" light would do at the current 1300 or 1700 lumens light would be like. Just goes to show that you DON'T need thousands of lumens to make a good light.

Cheers

The deal with the Nightrider is that you can put it on a low setting when riding in a group -- perhaps 150-300 lumen (depending on the light's max output), and its not annoying, although I don't ride with a mirror and don't know what might be annoying in that situation. Its not annoying without a mirror or in a passing situation (assuming the light is properly aimed).

I do know that even without a mirror, having a guy behind me with a bright flashing light is really annoying. That happened to me the other night, and I thought I was going to get steamrolled by some fast passing cyclist, but it turns out the guy was probably 50 yards behind me and never passed.

Speaking of lights, I was rolling around with a friend out in the country last weekend, and this cyclist with a super-bright headlight comes up behind us -- but I didn't even register it as a bike. I thought it was a car with blinding lights, and it wasn't passing. I was getting really annoyed. I looked back again, and this racer dude and his bright headlight were glued to my rear wheel. First off, get the f*** off my wheel. Second, do you really need a car headlight for riding in the day? My friend and I were riding at a chatting pace, so this guy finally went by. And for my rant within a rant, this guy was part of a growing group of oddballs who jump on my wheel, say nothing and then drop off or ride away. I think they're spin-class heroes who watch a few Youtube racing videos and get on one of the local Cat 5 teams. Reasonably fit but with the social skills of a zombie.

The bicycling movie, "AMERICAN FLYERS" dealt with how to deal with "WHEEL SUCKERS" by "SHAKE and BREAK" riding to throw them off your wheel.

"WHEEL SUCKERS" can be very dangerous as many of them don't have the skill needed to avoid lapping your wheel if you have to slow down. I do NOT allow any bicyclist of unknown skill to ride on my wheel nor do I ride the wheel of any unknown rider.

These days, I can't even ship an empty box for that low a price. The
overhead and handling are more than the product is worth. I don't
know how the Chinese manage to ship sub $1 products. Perfection has
its price tag and I suspect it will be easier to squeeze the extra
cash out of Jeorg than to design something that cheap.

Minimum 3000lm, probably with flash modes and low and high beam. (Note:
Lux means nothing to him, it's all in the lumens, Man).

Is that Chinese lumens or conventional lumens? I could probably do
that for Chinese lumens, which increase in value with every
advertisement and review.

Three week battery life on high beam.

That will require a physically large battery pile. Easy to handle
spare batteries might be more useful for extended operation.

Military grade design (Water proof, aerospace temperature spec.,
corrosion resistant, etc.)

MIL-STD-810 is what's commonly specified.
https://en.wikipedia.org/wiki/MIL-STD-810
http://www.atec.army.mil/publications/Mil-Std-810G/Mil-Std-810G.pdf
I've done a few marine radios that can pass most of the important
parts. None can pass everything. I was thinking a modular approach
might help here. Some modules would be used for normal cycling, while
others for dirt, rain, snow, hail, hurricane, alien invasion, etc.

Unbreakable mounting boss.

No possible. Jeorg can break anything.

All rounded edges for safe crashing (better if it has a built in airbag).

Many years ago, I helped clean up the design of a handheld radio made
from molded rubber. You could throw it against a brick wall and it
would survive. Well, mostly survive because there were some necessary
projections (knobs, switches, antenna, etc) that tended to break if
hit hard. Still, it was much better than an aluminum or plastic hard
case. That might be the solution for an impact tolerant headlight
package. Bend, not break.

EM Pulse safe.

Jeorg can do that himself. EMC compatibility is his specialty.

Repels mountain lions, motorists, motorcyclists, flying rocks and angry
bees.

Sigh. Add a built in smoke screen, shotgun, and trench mortar (pro
model).

Jay, did I miss something?
Oh, if it could light a fire and make a hot drink, that would be nice.

Hmmm... How many lux or foot candles does it take to ignite paper? The
ignition point is around 230C which is easily done with an optical
concentrator (lens). Can I trade the hot drink dispenser for a death
ray?

Yup, guilty as charged. I got all excited about lighting fires and

It's really rare for someone to have a powerful light in flash mode at
night. It's as annoying to the rider with the flashing light as it is to
others.

Speaking of lights, yesterday I saw someone with a hub dynamo, the third
one I've seen in 2015. He was on a BikesDirect Motobecane Elite 8
http://www.bikesdirect.com/products/motobecane/elite_8-speed-nexus.htm. He
had a front wheel from Peter White with a Shimano hub dynamo. But he was
using an old Busch & Müller incandescent front light. All that money for
a replacement wheel and he's using such an ancient, weak light. He said
that he still had two more bulbs left and once those were gone he'd get
a better light.

He was telling me how much he is in to BikesDirect and Motobecane. He
has one of the titanium Motobecanes for his road bike. Those are a heck
of a deal, using titanium frames from the same Taiwanese manufacturer
that a lot of much more expensive titanium frames come from
