New 4100 Lumen Flashlight Can Set Things On Fire

i4u writes "Engadget is reporting that Wicked Lasers has introduced The Torch. It is the world's brightest and most powerful flashlight. The Flashlight is capable of melting plastic, lighting paper on fire within seconds, and if you like, fry an egg or a marshmallow on a stick. At 4100 lumens, The Torch is 100 lumens more powerful than The Polarion Helios, the former most powerful flashlight, and retails for around $300. The Torch is apparently also undergoing review at the Guinness Book of World Records."

      I would really appreciate it if all my extension cords were clearly labeled for recommended maximum voltage. I'll assume you are serious and that isn't trollbait.

      Firstly, every cord *SHOULD* be labeled with maximium voltage... most likely 600V for most equipment. This is based on the voltage the insulation on the wires can withstand in a normal environment.

      What you likely meant to say is the maximum AMPERAGE (or wattage, which is voltage*amperage) a cable is designed for. This is a much harder thing to spec... just like a CPU, it depends what the temperature is. The larger a conductor (think cross-sectional area), the less resistance it has, and the less current will be lost to heat while in use. It is this heat that makes things unpleasant... you could take a "standard" cord and run 29384092385902380953A through it, but not for more than a millisecond or two whilst the metal melts and subsequently vaporizes in an explosive poof at room temperature.

      However, if you put it in liquid nitrogen, you likely will increase that time by several orders of magnitude... more assuming you can keep the cold flowing in (maybe a continual stream of L/N?)

      Coming back to reality, it may be safe to run your vacuum cleaner for a few minutes on the cord, even if it gets warm... assuming you *KNOW* it is getting warm, and you will stop using it shortly. Where it isn't safe is if you run a heater off of an undersized cord, then throw a rug on top of it to further keep ambient losses from cooling the cord, then spill something with a low flashpoint on the rug.

      Lumens are the total energy output of the bulb, and doesn't change even if I focus the beam.
      Think of light coming out of a flashlight as a cone, the more concentrated the light is, the higher the candlepower is.

      So when you're using a Mag light and you change the focus of the beam, you're changing the candlepower.

    Why not? I'll admit I consider most people abysmally stupid, but they should have a pretty good grasp of the idea that you can't safely run a 20ga 100ft cord from your basement to your garage "beer fridge".

    I usually think of myself as not abysmally stupid, but why can't I safely run a 20ga 100ft cord from my basement to my garage beer fridge? The purpose of the cord is to connect an outlet at one end to an appliance at the other.

    Does it matter that one end is in my basement and the other is in my garage? I know some cords are rated for outdoor use and some are not, but what if my garage is attached? Is there something intuitively obvious about 20ga cords that aren't suitable for beer fridges? And how do you know if my beer fridge is one of those little travel jobbies that can run off AC or 12-volt DC, or if my beer fridge is a full size Kenmore? (I drink a lot of beer.)

    Something so "mind-numbingly obvious" should be easy to explain. Maybe I'm just abysmally stupid.

    1. Re:Just curious by WhiteWolf666 · · Score: 5, Informative

      I'll assume this is a serious query. It isn't all that obvious.

      A 20gauge cord is most likely not capable of carrying enough amperage to power your beer fridge without either A)heating up, or B)outright failing.

      Situation A: A 100ft cord that heats up to unsafe temperatures may start a fire with any number of low-flashpoint items between your garage and basement.

      Situation B: Failing outright means that the cord heats up to sufficient temperatures in order melt the insulation off, exposing bare, high-temperature, semi-high voltage wires to the environment. They may spark, which can easily start a fire, the insulation might burn or char, and the exposed wires represent an electrocution hazard. This would be unsafe for a 4ft core, but a 100ft cord represents a line of death stretching the length of your house.

      Take a look at http://www.interfacebus.com/Reference_Cable_AWG_Sizes.html . Those are conservative numbers for load carrying capacity, and deemed "safe" for 100ft or longer runs. You can potentially multiply those numbers by 2-3 for shorter runs.

      Even so, 20 gauge wire should really only be used for a 2-6 amp load; and on the lower end of that scale for a longer (100 ft+) run. A pretty average, smallish home fridge has a "max" current draw of 15 amps. Even your beer-mini-fridge probably draws 7-8 peak. 7-8 is greater than 2, and as such, is a fire hazard. And, with a 100ft run, most people would probably stick it under a rug, which results in even MORE heat buildup.

      The thing about it that makes it worse is that the circuit breaker will only protect you against over-current based upon the wiring load (assuming the electrician did a good job), not electrical cords, particularly wimpy electric cords. The only time the circuit breaker will kick in is after the electrical cord has shorted, and it may be too late by that point. If its a ground fault, and not a fire, and not an electrocution, a GFCI circuit might protect you, but it'll probably be too late for that, as well.

      That all being said, it's not common knowledge; but it should be. It takes a bit to educate yourself on this stuff, but its important knowledge, and a lot of lives could be saved, and fires stopped, if they taught this stuff in highschool.

      IMHO, its a bit pretentious to say that this, stuff is "common sense". The little endian nature of the gauge scale (not to mention that it is logarithmic so 19 gauge is 2x the diameter of 20 gauge), and the unclear nature of the warnings on the stuff is kinda useless. It would make far more sense to make the Amperage of all devices clearer (peak), and simply put "This cable can carrying X amps at Y temperature, and is unsafe for use at higher temperatures" on extension cables.

      For long distances you may also need to take into account voltage drop...the cord itself may be fine but it may not be able to provide the proper voltage at the far end. Going one size thicker is usually sufficient to deal with this.

    3. Re:Just curious by uglyduckling · · Score: 2, Informative

      All cables have a resistance, which can be quoted as ohms per metre. So a cable that works fine for a 3m distance may well drop the voltage significantly over a 20-30m run. Thick conductors of the same material have a lower resistance per metre, so in general it's better to use the thickest cable you can for runs of more than a couple of metres, if you're going to be drawing a significant amount of power. (Significant means anything with a heater or a motor, or multiple small pieces of equipment). You can think about it like water pipes - narrow pipes will be at a higher pressure to deliver the same volume of water per second. It's also worth remembering that the energy lost by the voltage drop has to go somewhere, and that somewhere is heat. Depending on where the cables are run this could be a safety issue.

      Having said that I would expect your little beer fridge actually draws very little current and wouldn't be a problem on a narrow guage cable.

    Seems the GP was pointing out the reality distortion inherent in the article. The summary mentions that the torch can set things alight, and that it is quite bright at 4100 Lumens. Most people at this point seemed to have connected the dots to think that the brightness is related to its setting things on fire.

    Not true.

    Lumens specifically measures the visible light, and as far as brightness goes 4100 is pretty meager for a bulb, quite good for a handheld device though. Why is that a spotlight can put out 15-25,000 lumens yet the beam does not even feel warm? Reference (PDF) (and yes, I have tested this first-hand).

    The heat generated is by a light is completely irrelevant to its lumens rating, so whilst in nerdland it is quite correct that heat is just another wavelength of light, in this case the heat and light are two separate things. The light is the 4100 lumens boast, and the heat is the invisible and unmeasured infrared source coming from the bulb.

    First of all the Wicked Laser flashlight in question doesn't put out 4100 Lumens. Real world testing shows that the formulas used to estimate the lumens of the bulb in that flashlight are about 2x as high as they really are at the power level the light is using.

    Second, the light coming from the Wicked Lasers flashlight isn't very well collimated. It's one thing to make a lights that seems bright from 3' away. It's another to make one that seems bright from miles away. Being able to put a visible spot on a cloud 4 miles away or light up buildings from 6.2km away is a lot more impressive than lighting stuff on fire from a few inches away regardless of the lumen output.

    Finally, There are far more powerful lights (in terms of lumens) made by other members on the CandlePower Forums. There is one light with 14000 bulb lumen. So, it's certainly not the worlds brightest flashlight.
