    90 lumens more than sufficient, as long as it's focused appropriately.

    I'm not saying that more isn't better, but my Planet Bike 1w Blaze puts out something like 45 lumens, and it's sufficient. It's not awesome, but it's adequate for the roads. It only really becomes inadequate when my night vision is ruined by an oncoming car.

    (Just for the record, I do have several brighter lights -- a 135 lumen Cygo-Lite, 400 lumen P7 flashlight, 900 lumen Magicshine. They beat the Blaze handily, but even so, the Blaze is adequate.)

    Ultimately, if they wanted to make a law, they should have based it on lumens rather than watts.
    A AAA alkaline battery only has 625 mAh so it's only 0.9 watt hours. I doubt very highly that you could get 2 hours of continuous service out of an incandescent pen light. And a whole lot of that is going to be turned into heat energy.

    I don't know the real output of a pen light. Long ago someone told me that it was a 3 watt light (in another discussion about what is adequate for night riding). You might be able to get 45 lumens out of it depending on how fresh the batteries are. The point, however, was that that is what a 1 W light gives out (or something similar). It certainly isn't adequate for walking a bike much less riding one

    By adequate light, I mean a light that isn't washed out by other sources and can be seen by other road users against a background of other lights. 90 lumens is pretty dim and, realistically, isn't a light you should be trusting your life too. As a back-up light to a failure of your main system and on very quiet roads, you can use it. But I certainly wouldn't be bombing down any roads at much over walking speed with it

    You're helping me disprove your point -- there's no way these lights can put out three watts.

    Though you're wrong about the capacity of AAA cells -- for example, these AAA batteries are rated at 1250 mAh, and you can do better than that (for more money, of course.) Most AAA NiMH cells peak at about 1000 mAh.
    I doubt very highly that you could get 2 hours of continuous service out of an incandescent pen light. And a whole lot of that is going to be turned into heat energy.
    Two hours is certainly doable ... though it'll get dim at the end. As for heat energy, ALL lights turn most of their energy into heat -- even the most efficient LEDs are only 22% efficient -- that leave 78% that goes into heat. (Or light that we can't see, but that's just as useful as heat.)

    As for the wattage rating, if they say a one watt light -- that means one watt input, not one watt of light output. It doesn't matter how much usable light it makes. It's why watts was a silly thing to base a law on -- lumens would be a much better criteria to use, even if people are less familiar with it.
    The point, however, was that that is what a 1 W light gives out (or something similar).
    You advertised it as being three watts, not one watt. But I don't think it's even one watt -- but I haven't measured it either. I'm guessing it's slightly less than one watt.

    But even if it's one watt, it's not a particularly efficient one watt light. You can do several times better, perhaps an order of magnitude better. At one watt, the Planet Bike Blaze 1w is pretty good, for example.
    By adequate light, I mean a light that isn't washed out by other sources and can be seen by other road users against a background of other lights.
    At some level, even a halogen car headlight is washed out by other sources and can't be seen against a background of other lights.
    90 lumens is pretty dim and, realistically, isn't a light you should be trusting your life too.
    If I'm trusting my life to it, I want 100,000 lumens. Bright as sunlight, coming from the front of my bike, please! Obviously that's not practical, so we settle for a whole lot less. If it's aimed in the right place, 90 lumens is usually adequate for road use. (I'd want more, more spread out for riding a trail.) Yes, if there's a car right behind you, they may not notice your light -- but they probably know there's a car behind you, so by avoiding the car, they'll avoid you.

    You are getting hung up on details. The light I showed is an example of the kind of light that is rated at around 3 watts and is the kind of light that wastan's city council would deem appropriate. It's not an LED or even a halogen but a tungsten lamp that is of the kind that a true 'flashlight' was designed around. The power draw of the old flashlight was so high that they could only be flashed on and off. The battery wouldn't last for more than a few minutes at power. Pen lights (tungsten ones) won't last 2 hours when switched on. You'd be lucky to get 30 minutes and it probably uses 2 AAA batteries.

    You'll get no argument from me that lumens is a better way of measuring the light output. Lux might even be better. But most people aren't going to use that as a measure of light. They are very resistant to change and will probably tell you that watts are the measurement of the bible or some such silliness

    I certainly would never suggest you ride a bicycle of any kind with a 1W (or 3W) pen light. Of course you can do better. For about the same price, you can do better than the Planet Bike Blaze. A Deal Extreme MTE P7 SSR light is only $35 (about double the price of the 1W Blaze) and has almost 100 times the light. I don't know why people bother with something like the Blaze except as a back-up light.

    I work with a woman who uses a Blaze and she constantly complains about cracks and potholes and how painful her ride is at night. I tried to convince her to not buy the Blaze when she was shopping but she didn't listen. What are you going do?

    No, lumens are better than lux. For example, a laser would have an extremely high lux output -- but be useless as a bike light.

    Personally, I'd prefer the law stick to the old `visible from X feet away' where X is at least 500. At least that's something the police can understand, and doesn't penalize more efficient lights.
    A Deal Extreme MTE P7 SSR light is only $35 (about double the price of the 1W Blaze) and has almost 100 times the light.
    It's $35 + $10 for two batteries + $12 for a charger. And the Blaze is about $32-$40 (plus two AA batteries), so it's less than twice as expensive, even when you consider that it costs more than $35 to get the DE light going.

    And it's only about 8x the light -- 400 vs 50 lumens. But sure, if 100x vs. 8x is simply a detail, I guess I'm hung up on them.
    I don't know why people bother with something like the Blaze except as a back-up light.
    The DE light you referred to is fragile -- vibrations can cause it to stop working, and will cause it to switch modes. It takes non-standard batteries that may be difficult to get if you're on a long trip away from your charger. It's beam pattern is far from optimal -- it's spread too wide, so you have to aim it down more to keep from blinding people. And the $1.55 mounts are acceptable, but a good bump could still send it flying. If you actually use the high mode, it only lasts about 90 minutes? (The low mode puts out, what, 100 lumens and lasts 8 hours? That's more practical, but it's only twice the light of the Blaze.)

    The Blaze 1w is far more rugged and has a far better beam pattern -- so it has 1/8th the light, but it uses it better. And it's got the best flash pattern I've ever seen, if you're into flashing lights. It's a damn good light -- it's just not as bright as some others.

    The Deal Extreme light is good, but it's not perfect. Certainly, I would never ride with just it -- I've had it break on me too many times. (So far, they've been things I could fix myself, but it wasn't something I'd want to do on the side of the road in the dark.) So I use the Blaze 1w as a backup light -- but it gets pressed into service far more often than a backup light should.

    I have tried a number of bicycle headlights and like a light bright enough to show the potholes in the streets in time to avoid them.

    The Shimano dynamo headlight is a incandescent bulb and puts out a "to be seen by" light level in my experience. I have never seen a lumens or lux output listed but it is not much, 5 fireflies level maybe. Shimano uses a higher voltage rated lamp to keep it from blowing at high speeds but that decreases the light output at any normal bicycle speed. Too cheap apparently to put a voltage limiter circuit in their headlamp.

    The Lumotec IQ Cyo I replaced it with is MUCH brighter and more effective and is an LED dynamo powered headlight. I believe it is in the 60 to 90 Lumens range but it has a well shaped beam with a vertical cutoff as is required in Germany. More effective lighting than I have seen from any approximately 100 Lumens claimed light output battery headlight I have tried or seen.

    Light On! now has an American made dynamo headlight on the market for which they claim 350 Lumens light output, not bad for a 3W dynamo if accurate. I want to try it to compare with the IQ Cyo.

    http://lightonlights.com/dynolight/

    I have run a 600 lumens claimed output battery powered bicycle headlight myself with no adverse reaction from drivers so I believe that when properly aimed they do not find it objectionable.

    If high power LED headlights on bikes do present a hazard to drivers or pedestrians then I suspect that we will see NHTSA, CPSC or DOT regulations on beam shapes and or maximum output allowed. 900 to 1200 Lumens bike LED headlights are now readily available if you want to spend the $$$.

    As a motorist and bicyclist the headlights I find most objectionable are the HID lights now installed on some cars. They need a sharper cutoff to be less glaring to oncoming traffic IMO.

    Lux takes into account beam spread which would give you more information about how the light would perform in the real world. You would, however, have to specify the distance from the lamp to the target. Lumens gives you the raw power of the lamp but lux tells you more about what you get and where you get it. I said it might be better.

    I think, in this long Odysseusian thread...oh look, Sirens......that I stated that the distance measure is probably better.

    I found a couple of sites that had the Blaze for $18. But I've also found places that have the 18650 batteries for around $4 a 2 pack. You can find chargers for as little as $4.

    However, to compare apples to apples, you'd need rechargeables for the Blaze too. They run about the same as the 18650 on a per battery price and the charger would be the same.

    It's a wash on price difference.

    D'oh! I typed 100 and meant 10. Fat fingers and poor editing Sorry.

    Our resident light expert has gone to the trouble of measuring the light out put of the Magicshine P7 for which I thank him. Assuming a similar output from the same emitter (others have said that the MTE P7 is brighter), he came up with 760 lumens on high for the 2 mode light. That's a bit more than 15 times.

    First, I'm well aware of the vibration problem. I've mention it myself. I suggest people don't use the 5 mode lamp and just go with the 2 mode (I personally have no use for the flashy modes...damn! Something I share with out resident light expert).

    I'm not talking about using the light on tour. Most light usage is going to occur when commuting. If you need more battery power for longer rides, get more batteries! If you need a light for when you are on a long trip away from home, there are lots of other alternatives...the Blaze being one of them. However, if I need light while on a tour, for example, I'll probably carry a LED headlamp that is far more useful around camp than a bike light. I also don't ride my bike at night while on tour.

    For commuting, however, you can find external battery packs that increase the run time of the MTE light. Turboferret sells battery packs and dumby cells for the conversion. I have them, but I haven't done the conversion yet.

    The beam pattern for the MTE isn't that bad. If you've looked at my other system, you'll know that I throw bucket loads of light out. I like illumination! The beam pattern on the MTE is similar to my MR16 halogen with a bit more of a donut hole in one of my lights but it's not really an issue. A wider beam looks more like a car and motorists are often fooled by that. I have had some close calls with an LED that was too narrowly focused and much prefer light spillage to the side.

    I made my own mounts that mate to my halogen mounting system. Much more rugged and secure than anything I've run across. I did, however, not lock one in place and dropped the lamp on a bump. The light bounced around on the ground and is dinged but it still functions well. It's not a delicate as you think

    90 minutes, however, is a very decent run time for a small package. I do an 18 mile commute (round trip) and that would cover it nicely. In the interest of honesty, I will be shifting over to my heavier but far higher output halogens once I have to ride under lights both ways. For me, more is better

    Matter of opinion. I've dropped mine as I said and it still works well. A very tight beam pattern isn't the best in my experience. I don't use the flashy modes on any light. I'd rather put out raw power to announce my presence rather than try to catch people's attention with a strobe. And since I like the raw power, I have little use for a lower intensity light.

    Like I said before, I know someone who has the Blaze and she complains about hitting potholes she can't see all the time.

    I'll agree that the multimode is not a good light. The 2 mode is, however. None of the problems.

    I got caught out on Hermosa Creek Trail above Durango a couple of years ago while mountain biking without light, without food, without water, without fire...and kinda without a clue Since then I carry a backup to my backup lights. I even carry a backup to those. Along with a bunch of other stuff I should have been carrying in the first place

    I have always used multiple lights on my commutes and I've had lots of instances where I've needed them. Relying on only one light is just dumb...too many people do it...but it's still just dumb

    He's revised the figure to 375 lumens, after re-checking his calculations. Still a nice measurement, and still a nice light for the price.

    I found a couple of sites that had the Blaze for $18.
    Really? Where?
    But I've also found places that have the 18650 batteries for around $4 a 2 pack.
    Where? Do they have the low voltage cutoffs?
    Our resident light expert has gone to the trouble of measuring the light out put of the Magicshine P7 for which I thank him. Assuming a similar output from the same emitter (others have said that the MTE P7 is brighter), he came up with 760 lumens on high for the 2 mode light. That's a bit more than 15 times.
    First, that's a different light, even if the emitter is the same. Second, it's $80-$95 depending on where you get it. Third, you can't assume the same output because it has the same LED -- the Magicshine puts 7.2 to 8.4 volts into the LED (or it's control circuit), where the flashlight puts 3.6 to 4.2 volts.

    I own both. The Magicshine IS significantly brighter than the DE flashlight, even with the same emitter.
    First, I'm well aware of the vibration problem. I've mention it myself. I suggest people don't use the 5 mode lamp and just go with the 2 mode
    The problems go beyond merely changing mode. I've had hard bumps knock the LED assembly loose more than once -- that would happen to either light.

    Also, I have both the two and five mode lights. The two mode light uses a resistor to reduce the power for the low mode, where the five mode light cycles the the light on and off really fast. The latter is far more efficient. Considering that I use the lower power modes most of the time, that's a concern.

    I have backup lights for my commute! They're attached to the front of RTD buses! Also works for flats, bent cranks, getting hit by a car, running into a chain stretched across the parking lot, etc. (All of which have happened to me over the past few years! )

    I love living in a city with decent mass transit!

    The backups are for getting me from where I am to where the buses are

    Google is your friend 18650 protected circuit Ultrafires here The Planet Blaze I found was for the 1/2W. Didn't notice the difference at the time. That just makes the 1W blaze less of a deal. Same price as the Deal Extreme flashlight, 15 times less light

    I don't have the Magicshine. I've been going on what I've read on light output and on the emitter. Some people have reported that they are not as bright as the MTE. I'm not likely to see them side by side either because I already have lights that will work for my needs. No matter if the Magic shine is $75 (Deal Extreme had that price recently) or $85 or $90, they are still a damned good deal. Let's not quibble about $10.

    As for reduced power, I don't believe in it. Never have used it on lights that had it. I turn 'em on and leave 'em on high. If I need a longer run time, I just add batteries as appropriate. You might be able to squeeze 8 hours out of a battery but why bother? That just means you have to keep track of how long your lights have been in use. I recharge after each day's use. I don't really like finding myself in the dark unexpectedly...it's that whole backup to backups thing

    I managed to piss off a cop with my P7 today. Over my 15 mile nightly loop, I got cut off more than usual and had several cars pull out right in front of me even when I was sitting in high mode. This kinda pissed me off so I started using the strobe light. When I was sitting at the intersection, a cop started strobing his car at me probably telling me to turn it down or something. At this point I was expecting to get pulled over, luckily nothing happened. Is there some law against strobe lights that I should be worried about?

    Maybe, but common sense says 'don't be a jerk'.

    The law against strobed front lights is the law of common sence. Strobes are way too distracting for headlight use. Just because LED sources CAN be strobed doesn't mean it's a good idea. Just because marketing and advertising hacks want to put another "feature" on the packaging doesn't mean it's a good idea to strobe a front light.

    Ask an epileptic person if they think a strobed headlight is a good idea. Strobed lights are not necessary for better visibility on the street. Collisions happen because bicyclists ride on sidewalks, on the wrong side of the road, too close to parked cars, too fast for conditions, without mirrors, and distracted. Also because car drivers drive distracted, without knowledge of proper lane usage, don't use their turn signals, and don't know where the front of their vehicle is in relation to themselves ( which is why many now leave so much space in front of them while waiting at stops). There's no evidence that strobing a headlight makes any difference.

    Strobed white lights should be reserved for emergency vehicles. As with helmet mounted headlights, they scream out "look at me, me, me" without any consideration for anyone else on the road, and by their overly distracting presence make everyone else on the road at greater risk.

    Just my opinion. Don't allow marketing hype and fear mongering guide your actions. Nobody strobed their headlights untill LEDs started being used for that purpose. Strobed headlights are pure marketing BS.

    So... you're saying that all those emergency vehicles out there cause MORE accidents because of their strobed lights???

    And nobody strobed their headlights before LED's started being used?

    WHERE do you come up with your facts?

    You should stick with your measurements and numbers and leave real life to those who can deal with it.

    I didn't say that about emergency vehicles. Not even close.

    Show us a non-LED bike headlight that strobed, from BEFORE LEDs started being sold with that feature. Show us a strobed HID or halogen lamp. Untill then, STFU and I'll disregard your recommendation.

    How about modulating headlamps for motorcycles, which are specifically allowed under both Canadian and US transportation laws...and are indeed thought to make motorcycles more visible. In fact, didn't I hear that they are now available for automobiles?

    You really need to work on your people skills

    Long ago there was a product called Lightbrain (no longer made) which was a voltage regulator for halogen lights. It rapid pulsed the light to improve battery efficiency. It also included a strobe mode.

    The Niterider Digital Pro had a strobe mode too. Look here for a review. The Digital Pro was being sold long before LED.

    Perhaps you ought to reconsider telling anyone to shut up

    Show us the pre-LED modulated motorcycle headlights. Has anyone here ever seen a motorcycle with a strobed headlight? Not modulated above the flicker rate, STROBED like bike headlights are?

    I have NEVER seen such a motorcycle light. NEVER. A motorcycle headlight blinking like bike headlights now do?!? C'mon Mr. Giving-the-finger-to-everyone, back up the ridiculous garbage you just spewed out.

    Still drinking I see. There's obviously a lot you've never seen...sounds like a personal problem.

    You see, just more personal attacking and nothing to back up your ridiculous words. Real easy to shout garbage from the cheap seats, isn't it? As I said before, you're just like a drunk at the bar who took a physics class 30 years ago and now thinks he knows how everything works.
