Bicycle Lights?

[Blindasabat]

I have looked at either finding/buying an LED headlight or modding my existing Vistalite Nightstick 10 watt MR-10 bulb to run LED, but no success so far. All I have been looking for is longer run time as my 10 Watt Halogen on a helmet mount has a good enough beam to ride up to 38MPH (61KPH) in a 12 hour mountain bike race last summer. I need a similar beam, helmet mounted (makes a big difference off road - I consider handlebar mount a n inefficient waste of light and battery), about 6 degrees spread with little/dim spill.
In reading other threads and web sites of people that tried, it seems LED is not as efficient as HID, and only just about equal to halogen (but for twice the price). HID systems for sale seem to be overkill for me as they are often trying to impress you with a wall of light, when you only need a spot on the trail. Too broad a beam spends too much time lighting up the leaves hanging over the trail and wasting my battery. I could use a seven watt HID, but they all want to sell $300 twenty watt systems. So I am staying with my perfectly good Vistalite, though I just ordered a new battery (mine are a couple of years old and have been mistreated so they only have 45min run time anymore) and a 20 watt bulb just to try out (it was $2.5 with the battery). I think LED still has a way to go for true off-roadability without spending well over the $75 I spent on my lights. The Cateye Doubleshot system looks good, as does the Blackburn system, but seem to be only the same performance as mine for over $150.
I have yet to find a handlebar mount for a Mag size torch that could hold it steady over terrain at speed.
If I could find a more efficient Xenon or Krypton MR-10/11 6V bulb, that would be ideal for now.

HID....

I ride aggresive singletrack at night.
Light and Motion ARC HID, Best one around. I got mine for 265. You just have to be patient and check online superstores like Jenson, etc.

I've used a Light&Motion ARC HID for several years now and it really is very good. Even if you don't think you need that much light to see by, the other side of the equation is that motorists take notice. Not that you are blinding them (I have never had anyone flash high beams at me), but the color temperature, brightness, and point-source nature of the light get their attention and more importantly, changes their behavior from "oh, it's just a bike", to "this is something I need to reckon with". It dramatically cuts down on bad behavior at intersections, especially. And part of the effect comes from the considerable amount of light that some claim is "wasted" in the sidespill. I don't see it as waste at all, except possibly overhead, but there is more than enough light to go around. Their smart charger does a good job at keeping the NiMH battery pack up to snuff. It's nice to have a reliable 3 hours of serious light, time after time. I often need 2 to 2 1/2 hours of that runtime.

I have long used a Vistalite strobe for the rear. Recently I became aware that the strobe isn't nearly as bright as it once was -- it has seen a lot of flashes in the seven or so years I've used it -- and they don't make them anymore. I have just changed to a Cateye LD1000 LED tail light. Extremely bright and visible for well over 180 degrees. Still, the lion's share of the light is directed in a fairly narrow zone to the rear (and 2 smaller ones to the side). That does make it carry WAY down the road, but thinking of maybe frosting or faceting a couple of the "lenses" to make it a just a bit more omnidirectional. Other nice things are that it has 2 separately controllable banks of LEDs, and gives decent runtime off of rechargeable AA's.

I am looking for a 4-AA LED solution to act as a backup for my headlight. There are some parts of my current route that are better taken without a single-point-of-failure as far as lighting is concerned -- need at least enough light to safely come to a stop if the main light goes out.

The Vistilite HOT Halogen bulbs have a nice white color until the battery starts to run down. The directions say to recharge once the beam starts to turn yellow.
The replacement bulbs I got from Batteryspace didn't fit nor were they near as white.
I ride amost exclusively trails at night. The best defense for night riding on the road is not to do it. I ride less than a kilometer on paved road and a few more km on unused dirt roads to get to the singletrack trail. The beam on my helmet mount can be flashed at a driver of a car very quickly (and for only a millisecond) with a simple head movement to make them behave.
I am doing a one day ride across Michigan this summer that starts in the early dark that requires lights, but since I will finish before dark, I only want something small, handlebar mounted, removeable, and light to comply with the rules while I ride safely in the 300+ rider group for the first few dozen miles in the morning.

When I was using my Vistalite and needed replacement bulbs, I finally found them at Reflectalite.com. Their GH44 was a good replacement for the 6V 10W bulb I needed. Would make a decent bulb for a custom flashlight if I ever get around to it.

For mountainbiking at night I currently use a Niterider Digital pro 12E mounted to my handlebars which is a dual beam halogen unit with many brightness levels and modes. I combine that with a Marwi Nightpro Extreme on my Helmet which is a 10 watt HID. The HID alone provides enough light to ride efectively at night, but the cool white color is not perfect for color rendition, but when combined with the halogen bar lamp it is easier to make out colors and depth perception is improved so it takes less effort and consious concentration to see where you are going. So with both lights running I can ride as fast at night in thick woods as I do during the day.

It's been said, or rumored (by Surefire), that 100lm/W LED's are just around the corner...so that's 3500 lumens for your 35 watt LED!

OK? I'm waiting. And, er, expect to be 3-5 years older, and, er, just waiting,....

I made a luxeon 1 watt bikelight for my city bike a couple of years ago. My issues were not having to deal with batteries, so I'm using a 2 watt Sturmey-Archer dynohub. I made a circuit using 3 supercapacitors, a voltage regulator, and a rectifier. The dynohub puts out about 6v AC. The circuit rectifies it, charges the super caps, and then goes through the regulator to the luxeon. I have a fraeon (sp?) optic on it. I am very satisfied with its performance. I have to ride about 100 yards for the caps to charge (the light comes on right away, it is always usable as long as you are in motion). After the caps charge, it will burn for several minutes when you aren't moving. The AC dynohub causes it to pulsate at lower speeds, but the caps keep it from going out, it pulses between a dimmer/brighter state. I actually like the pulsing, I believe it makes me more visible to traffic. I am embarassed to say that I have yet to make a proper housing for the light and the circuit. I intend to machine a proper housing, once I get my lathe up and running (I have to do some house wiring first). I want to redo the circuit board such that it is long and thin, so it will fit in the fork steering tube. I believe I could put two 1 watt luxeons on the circuit, but I've been happy with one. I need to hook up a tail light to the circuit. I am currently using a generic battery powered LED taillight. Most of my riding is in the well lit town, but I have ridden on paved unlit trails, and the light is good enough. I would like to upgrade the generator hub to a 3 watt Schmidt unit, and get more power out of the setup. I may get a proper etched circuit board made and try to sell a few, but I've been to busy with other things and my current unit works. I also have a Red Alert flasher on the bike. They don't make them anymore but they are really cool. You have a magnet on the spokes, and the light is mounted to the fork or rear seatstay. The light has a coil and 3 LEDs in it. Everytime the magnet goes by the light, it generates enough electricity to flash the LEDs. No batteries are involved. I have an amber one on front, and I was also given a broken red one for the rear. The red one is more sophisticated, it has a flasher circuit and some super caps in it, so it stays lit when you aren't moving. I wish they still made them. I managed to get them from a nice guy in the Netherlands. I sent him some euros and a hard to find (in the Netherlands) bike accessory.

I'm new to the group here, but I've been lurking on occasion for a year or so. I plan to make some flashlights. I have an Arc flashlight from their first run (I got a factory second) and, you won't believe this, I found a Surefire Ultra 2 on one of my late night bike rides. I hadn't been keeping up with flashlight tech since I got the Arc and made the bikelight. The U2 got me interested again, I was very impressed with it. I wouldn't have purchased a U2 before, but now that I have one, if I were to lose it, I would buy another. Of course, I also have an old maglight that I found, a minimag that is broken and somewhere, I hope to find my old 2D maglight. It has sentimental value to me (serial 20196201 BTW). I might have lost it, as I haven't seen it in years. I want to convert it to a 1w luxeon and use a Tadiran DD cell in it, just to keep it for emergency use. I'm getting off topic.

I used to use a Niterider 15 watt light, with the bottle shaped pack. It was a great light, but the battery was a hassel for me. I really like the generator setup. Especially the dynohub. I think my dynohub was made in 1975. I got it on ebay for $20. Had it made into a wheel for $100. I'm a bit of a bike nut, I want to make some city/urban/commuter bikes that are already equipped with lights and fenders and such. Currently my day job keeps me busy though.

I ride about 20km a day return 5 days a week - I have two options when it comes to which path I take:

1. Sydney's busiest & most dangerous motorway the M4
OR
2. The back alley cycleway that's a great place to sell drugs and mug people

When I'm in a hurry I take the M4 but when I want a workout I take the undulating cycleway which is largely unlit. Either way I need enough light to either a) scare junkies away or b) compete with car lighting so they see me in the breakdown lane.

I used to use a Nuwai 5w held on with cable ties & high density sponge to the top tube but it was no use on the M4 other than as a flasher. At night when the car's lights stop coming up from behind and your eyes have adjusted to the brightness you actually need a good light to see stones & glass on the road - at 50 - 60km/h (my motorway speed for most of the ride) you don't want a flat.

So then one morning I woke up and realised I needed more light. I now have my MAG85 taped to the top tube with duct tape and high density sponge between the metal bits - it's daylight in front of me and drivers not only notice me but they stare in amazement. It's run time of 37mins suits me ok but I am hoping to get those C Lions so that I can use a smaller, lighter 3C and a cyclopblock to get 1/2 the wieght and 1 hour run time. No commercial bike light I know of puts out 1000 lumens and at about $200 with FM battery holder it's a bargain.

Kromeke, there is a company here in the UK making possibly similar items. I haven't used them, and they look a bit expensive to me for what they are, but I guess any light is better than no light...

[kromeke]

sbothwell,
Thanks for that info. Different company, similar device. Red Alert has a US patent on theirs, so that may be why I can't find the Goodbye Batteries product here. When you say expensive, how much is it?

Sbothwell,
never mind, I found the pricing page.

Thanks agian for the link.

I've just bought an USE Exposure enduro turbo. http://www.use1.com/exposure/

Much too bright for my comuting needs but drivers give me much more respect when I blind them. Guess they think I'm a motorbike.
Website tells me it has 2 5w luxeons, one spot (lights up the building opposite where I work even with the street lights on) and one flood (which does a great job of lighting up all the potholes I have to ride over). No idea of the more technical aspects but it's a great light and the little I've used it off road has really impressed me plus there's no cables. The only down side is it cost me £270 ($470 US)(still, I managed to save nearly £100 of the retail price).

Review?

I can tell you these points:

1. have had them for ~8 years now
2. still on original bulbs
3. they have been used for many 24 hour mtn bike races
4. I don't think you could tear them up if you tried. All wires are reinforced and bolted into place.
5. all hardware is aluminum or stainless steel
6. idiot-proof operation
7. very sleek looking, great lines/cosmetic appeal
8. the optional quick-release mounts have been copied by prectically everyone else, but none has the quality/durability/toughness of the original TC model

I consider the lead-acid the low end battery, the nimh the mid range (yes it's lighter, but performs much worse under high load conditions), and the nicd the best. Yes, the plain old nicd. It's much more durable and tolerant of over-discharge, which WILL happen to you eventually.

These babies shows up on ebay fairly often. Compare the ebay photos with the CURRENT photos on TC's web site. If the pics match, then you are good to go. The light head is indestructible, and the battery can easily be rebuilt cheaply. That makes the ebay purchases a very good deal. I got a $300 set there (I have 4+ total sets) for about $90. I had to replace 1 broken bulb ($25) and I had a working set of lights.

But if you want a specific recommendation, I'd get the s10 with the lead-acid battery and upgrade to the quick-release mount. It retails for only $100 plus about $15 for the mount. This will provide you with a tremendous light for cheap. They also have a crash-warranty, and provide extra parts for cheap if you are in a race.

How about a quick review of their low(er) end model? I only commute a half hour or so each way so I don't want to spend a ton of money but getting home alive IS a priority so I'd like to get something good

Does anyone make a Mil-Std. 1913 Rail handlebar mount? I was thinking a weapon light might work, like the Surefire X200.

 

[Flea Bag]

Does anyone make a Mil-Std. 1913 Rail handlebar mount? I was thinking a weapon light might work, like the Surefire X200.

I was looking at such an alternative too perhaps with weaver/Picatinny mounts for quicker detachment. However all weapon mounts I know of require paralled mounting of the flashlight instead of perpendicular as required by the handlebars.

So I thought I would try to find some straight 25 or 30mm diameter, 0 degree inwards bend bar-ends, then place them at the centre of the handlebar with two flashlights mounted underneath them for crash safety.

Mounted on the first bar-end would be the SF L6 pointed at the ground with an extra set of 17670 to give it an endurance of about 4 hours on constant on. The second would be an M4 with Z46 bezel and XM10 pressure switch tailcap pointed straight ahead at traffic. Tapping on the pressure switch would flash the light at cars to signal my approach. Otherwise, the M4 would be deactivated to conserve battery.

This solution was costly and slightly complicated and if I fell off my bike doing stunts or other such things, the metal mountings would not break-away like the plastic ones of dedicated bicycle lights and major damage would be done to my flashlights.

Also, flashlight weapon mounts are a controlled item here so I can't legally use them on a bicycle. I ended up ordering a helmet-mounted Jet Lites Blast HID with an option for handlebar mounting in case I wanted it. Should arrive next week.

Right now I'm depending on a C3 tied to a metal ruler and spare cyclocomputer mount. Works okay but is definitely a compromised solution.

The Exposure lights look damn nice, but whoah are they expensive. The Enduro Turbo is the kind of light I've pondered building myself, with both a focused spot and a wide angle flood, amd multiple output levels. The Joystick looks more reasonable (for a commuter like myself), but I have no reason to not stick with my L&M Vega for the time being.
