anyone make a nice quick release mount. I was looking at garmin's rail mount for my gps and thinking I might ask them it=f its made by someone else for them to see if I can get those parts and drill and tap a light to be able to connect to one.

Here's information on the lux of MR16 bulbs at nominal voltage for comparison. For a 20 W MR16 at 12V the lux at 30 cm (12") is 20,600. For a 35W MR16, the lux is 33,500. The 35W MR16 at 12V puts out a little less light then a 20W MR16 at 14.4V. However those numbers are for 38 degree bulbs which is a very wide angle flood. Narrow spots (12 degrees) would have more lumens per square meter but would cover less area.

And let's face it, bicycle lighting isn't driving much of any kind of market. Lamp development is being aimed at other, more lucrative markets. We are a fringe. We just happen to benefit...occassionally...from other people's investment.

If your lights blind oncoming traffic and cause other vehicles to crash, that's a disadvantage. If your lights cause you to be pulled over by the police, that's a disadvantage. I don't believe 4000 lumens are necessarily problematic, but I can think of plenty of scenarios in which significantly exceeding the output of vehicles around you could produce negative results for you or others around you. Even at a much smaller level, there are certain situations where I don't run my P7 at night. Almost all of these situations have to do with not wanting to stand out (at least until passing certain areas).

Depends on the distance from the lamp and the area that the light is spread over. Lux is equal to lumens/ sq. meter. Not a real good conversion available without knowing the area illuminated and distance from the bulb. And the Lux number would be different for different systems. For example the lux would be different for a 12 degree spot than for a 24 degree flood (halogen). LED would be different too.
Here's information on the lux of MR16 bulbs at nominal voltage for comparison. For a 20 W MR16 at 12V the lux at 30 cm (12") is 20,600. For a 35W MR16, the lux is 33,500.

I use it in the day time. Has a 6 hr bright run time, 8 hr low run time.
Is easy to recharge and people tell me That Light is Bright.
Here is the 17 Lux at Night. The car just happened to come down the street when I was taking the pic.

Thanks for the info.
That's a bright light 10 wheels! And you should easily do 20k miles since the only hill you have is the Kemah bridge (j/k).
However, I believe there is already 200 watt LED technology. It must be true if I read it on the interweb. Especially since it was in a pot growers forum..... Yes that's right, they can't wait to grow ganja with it.
The things you find with google.

Overvolting reduces the amperage draw. Amps = watts/volt. A 10 W bulb at 12V draws 0.8 A while the same bulb at 14.4 V draws 0.7A and puts out twice as much light.
I'll agree that for weight LEDs are king. For lumens...not so much. Per unit halogen still put out more light...or can be forced to put out more. Halogens...the ***** of the lighting world

That assumes the resistance is the same, but it might change a little because the lamp would be running hotter. But it's probably fairly close.

Ummmm, no. Light bulbs don't have a constant wattage regardless of voltage. If anything they have a constant resistance. Voltage = Amps * Ohms. So if you increase the voltage, you'll increase the current (and also increase the wattage, which is why they get brighter). If a 10W bulb at 12V draws .8A, then it's got a resistance of 15 ohms, and the same bulb at 14.4V would draw .96A. It would now be using 13.8W, so I doubt it would really be putting out twice as much light.

The real gain is in the heat of the filament. Hotter filament, more light, less life. Here's a GE sheet on halogens. Look on page 8 for the lumen output. At 20% overvoltage the lumen output goes up 185%

As for riding in dicey areas without light, that's not for me. I run them on full with the helmet light. If people think you are a car, they are less likely to jump out and grab you. If they do try anything funny, 1500 lumens of light in their face will blind them long enough for me to get away from them.
But, from a practical standpoint, I'm not worried about people. I worry more about the cars.

I wasn't talking about your lights specifically; my point was that it is possible for too much light to be a disadvantage. It sounds like you've got a good setup and have thought your lights out well.

There are situations where blinding a motorist is not only helpful but necessary. A helmet mounted light swept across the eyes (if necessary) can go a long way towards stopping those beast. I would never advocate doing it on a whim but there are times...even for me I know that they are going to have a blue dot in the middle of their vision to remind them for a while
However, in normal urban lighting conditions, having more light makes you stand out against a rather light crowded background. More is always better, in my opinion.

Plus its illegal to operate a directional light on a motor vehicle (like the ones police cars used to have on the A-pillars) as far as I know it most states. Your 1500 lummen helmet light, as you stated, is the rough equivelant of a car headlight,... which you can and have pointed at motorists.
I have some family members who have had eye surgery which produce halos around lights. Driving at night where bright lights are involved produce multiple halos in their vision. Shining a light at them may produce your intended result of them stopping, but it may confuse them as well since they may not be able to pinpoint your location because of the intensity of the light.
You are knowledgeable for sure, dispense your knowlege freely and are open to helping others which is GREAT..... but your delivery often comes off as boastful when you post you lumen output.
For sure, I would like brighter lights, and am a bit envious of your output...... but to put it another way.....
One of my best friends does really well for himself. He has a Lamborghini Gallardo which he bought new.... but when people ask him what he drives, he says a Honda Pilot. (Because he has one of those too). Just becuase he has the Lambo, does not mean he always has to SAY he has it.

As for the round reflector, don't assume that I have my lights aimed flat and level. My lights are targeted to shine on the road approximately 10 meters ahead. I want to bulk of my light hitting the ground to illuminate the road and not spraying off into the dark.
I've already made the point of lane position but I'll reiterate. We cyclists travel outside of the right wheel track. You'd have to have a very wide angle reflector or very, very poorly angled lights to shine glare into the eyes of a on-coming motorist. A very wide angle reflector or poorly angled lights do nothing for illuminating the road and, if the point is to illuminate the road, why would anyone ride with that setup?

Some times people may even see me and proceed anyway. Those people get the full face effect because a bit of a blue dot in their vision is better than me laying on the pavement under their car. But I only do that as a last resort.

You are not overboard at all. Light geeks aren't impressed. Some of us own single system that has more than double the output you have on your entire bar, those are blinding at 50 feet. It isn't really bright unless you are cranking out at least 900 lumens (you have no more than 300).
Here's what a 900+ lumen setup look like.

You can keep em coming for me. The few lighting upgrades I've made may be like slightly bigger globs of spit in the ocean, but I've made them with knowledge obtained here. And if I could manage to replace the memory of Chip's avatars with more lighting pictures.......

I by no means think you should keep your mouth shut. Quite the opposite, you tend to give great information, detailed and helpful responses, and are a true help to others on this sub-forum. I was merely commenting on the nature and tone of some of your posts. For the most part, you replies back are thoughtful and intelegent which is more than I can say for most internet forums I frequent.

The lights on my MDX is a mix of projectors and multi-reflector fogs. Both have HID's in them. I can see a sharp cuttoff on my lights 200+ yards away. I drive down the freeway and can see a horizontal beam pattern reflected on the sound barriers to the right of the car.
This movie shows a more normal view of the same tree. Outside of the main beam of my lights is pretty dark.
Noted. I was just saying its illegal for motor vehicles to have them because it can impare others, possibly causing an accident that may not involve you, but still may harm others. I agree with you,... I would rather them hit another car than me, so on that point I think I understand/agree with your position.

Amps = watts/volts = volts / resistanse. Resistance does not change with voltage. 12V 0.8A will draw 0.96A at 14.4V, or 13.8W.

OP, I think you should get one or two nice lights like a P7 instead of wasting your time changing out the batteries on so many low power lights.
cyccocommute, do you happen to have a guide for how you made your lighting system?

The filament resistance goes up with temperature, so it does change with voltage.
While I think this thread should be titled "lights. Lots and lots of lights." having multiple lights is good for visibility, but having them spaced out makes good sense, I wouldn't put them all in middle of the bars.

I have overvolted haogen bulbs they do work well but they eat batteries and you ahve to carry large battery packs around. I was running a 20w halogen overvolted to 16v. worked pretty well. better then my trail tek HID but I don't think ti was any better then my better aimed dinetto otte 600l and it weighed 4 times as much and needed 2 8 cell battery packs.
