  • LED or not

    Some people have told me that LED lights don't cut through smoke very well; some people have told me they do. What's the real truth?

    I'm looking for a right-angle light to hang on a coat.

    One firefighter told me that non-LED lights cut through smoke better but that, at least in his experience, lighting through smoke isn't actually particularly important. He prefers LED so as to have a brighter, longer-lasting (per charge) beam for utility purposes.

    But I've just read an older thread here in which someone said LED cuts through smoke better.

    Since I'm only just starting the basic firefighting course in a couple weeks, I have no experience to guide me. What kind of bulb cuts through smoke better, and how important is that anyway?

    Two lights in particular I'm considering are the Streamlight Survivor and the Pelican Big Ed. My station doesn't issue any kind of coat light so I'm pretty much free to pick whatever I want.

    If it makes a difference, I'm with a suburban FD, with actual structure fires few and far between. But of course I'd still want my gear to be ready for one in case I ever actually do get in one...

    I too have heard the same two arguments. Streamlight has discontinued the Survivor lights in anything but LED. So if you want Halogen/Xenon, it's Pelican or nothing.

    Here is how i break it down:

    Halogen/Xenon bulbs in Anglehead flashlights:

    Pro's:
    1. Bright, warm light. 72 lumens on the rechargeable. 48 lumens on the C battery version.
    2. Beam Color cuts smoke well.
    3. LIFETIME Warranty.

    Con's:
    1. High wattage gives poor battery life.
    2. Can be damaged by shock and vibration.
    3. Can be damaged if the bulb gets wet.
    4. Bulbs have a limited life. Can and do burn out, without warning.
    5. Produce heat and can create a spark if the bulb shatters.
    6. Streamlight has discontinued the Halogen versions. So it's Pelican or nothing.
    7. Uses C batteris which cost more, are heavier and make the light physically larger.

    Pelican Big Ed Xenon Rechargeable:
    Light Source: Xenon (Primary) Krypton (Back-up)
    Battery Burn Time: 2 hrs. (Primary) 5 hrs. (Back-up)
    Charging Time: 2.5 hrs
    Weight: 20.48oz Rechargeable version, 20.32oz C version.
    ---------------------------------------------------------------------------------------

    LED Anglehead Survivor flashlights:

    Pro's:

    1. Extremeley bright. Cuts better then most Halogen bulbs. High Beam: up to 21,000 candela peak beam intensity; 100 lumens; Low Beam: Up to 7,500 candela peak beam intensity; 32 lumens
    2. Bright white color offers much more light then any halogen/xenon bulb.
    3. Super low wattage gives super long battery life. Survivor LED battery life:
    Runtimes: NiCd – High: 3.5 hours; Low: 10+ hours; Flash: 7+ hours :::: Alkaline – High: 4 hours; Low: 14+ hours; Flash: 7+ hours
    4. Impervious to shock and vibration.
    5. LED's lifespan is usually 50 times+ that of halogen bulbs. Unlikley to ever need replacement. Survivor LED rated for 50,000 hours.
    6. Produces little to no heat. No chance of sparking.
    7. LED's do not typically fail instantly. They degrade slowly.
    8. Survivor light has the option of using a AA battery holder so if you have no rechargeable batteries, you can use easily available AA batteries.
    9. LIFETIME Warranty.
    10. Super lightweight. Do not have exact weight but it is less then the Big Ed by far. (We have both)

    Cons:

    1. Sometimes Higher initial cost, although offset dramatically by never having to buy spare bulbs.
    2. Intense white light can reflect more off of smoke. But the cutting power is worth it in my opinion.


    So i see it as a no brainer. Much longer run time and no fragile bulb to fail. I am going with LED. What little possible smoke cutting power a Halogen bulb may offer is not worth it to me because of all the downsides to it.

    Just my opinons.

      WD.....as usual....has done his research and it shows. The LED is definitely worth the money. HOWEVER, it is little to no help in a fire. No doubt it comes in handy on extrications, rescues, etc after dark. But for actual firefighting purposes, take it or leave it....jmo.

        WD6956, thank you for all the info and summarizing. I do have a question or two. About LED lights, you say, "Cuts better then most Halogen bulbs." But about halogen lights, you say, "Beam Color cuts smoke well," and in your conclusion, you say, "What little possible smoke cutting power a Halogen bulb may offer..."

        It seems that twice you say halogen cuts through smoke better, but you also say that LEDs cut through smoke better than most halogens. So I'm a bit confused about which one you are saying cuts through smoke better.

          LED...all the way...

          I work for a dept that has streamlight halogens on all the trucks. And every shift I clip one on to my scba. And every fire that I've had, I've pulled my streamlight LED strion off my radio strap and can see WAY better than anyone else.

          The LED is brighter, lasts longer, is more durable. The difference is that it's brightness actually reflects off the smoke more and therefore "cuts" through less. Kinda like driving with your brights on when it's foggy outside.

          But when there is that much smoke, the light isn't what guides you, it's just what makes you visible to your team. And when you use your light is when you're checking out a attic on a smoke investigation and/or in a larger house once the powers been cut.

          Get get the C4 streamlight right angle, you will not be dissapointed.

            we purchased survivor led alkaline lites 2 yrs ago. we also have some of the big ed's. we like them both. the only issue we have had with the survivor led lights is that when the batteries get low there is no indication, they just go out where ever u are. stay safe

              Sorry about being a bit confusing. I was working on one hour of sleep in the past 24 hours.

              Halogen/Xenon bulbs are not as intense as an LED light. They also are warmer in color (More yellow) then the pure white of LED lights. Because of that, the glare is less on smoke. Easier on the eyes. LED's are very intense and will throw a beam through thick smoke quite well, often better then any Halogen, BUT, they also create a lot of glare with light reflecting off the smoke. To some people, this is annoying, to me? i can deal with it.

              To have a better idea of what i am talking about, go to any shop (or find a buddy) who has an LED flashlight of some kind with a single, super bright LED, often refered to as C4 or Luxeon LED's. Any LED SureFire light will have one as will many of the new Streamlight lights. Even the new MagLight LED lights in all sizes use these. Then take a comparable Halogen/Xenon type light and go to a dark room. Turn each one on seperatley and project them at a wall and look at the beams and the reflection. Then aim the light vertically and don't stare into the beam, but look at the lens of the flashlight. You will see that the LED light hurts your eyes it is so intense. That is that pure white light that can give you excess glare.

              My anglehead light on my coat comes in handy for most outside chores and general lighting use. In a fire, it is never my primary search or navigation light. It's main purpose is to light up the area right around me so i can see my hands on the floor, see a search line, hose, etc. And it acts as a beacon for others to see me. I have yet to have any issue with it not working well in smoke any worse then a Halogen light. But i much prefer the reliability of the light over any others.

                I do actually have two very similar Surefire 6P variants, one a classic 6P with a xenon bulb (or some kind of halogen) and another with an LED, so I'll try what you were talking about.

                But if I understand what you're saying, it's that the LED throws more light...some of the more light gets to where you want it, and some of it glares back. If you can deal with the glare, there is, in fact, more light getting to where you're pointing. Is that pretty much it?

                  Yeah, those two might work. The SureFire Xenon bulbs are super bright though, so the test i described may not be as convincing. But you will have the idea.

                  Yes, that is what i am saying. You get a much more powerful beam and with that power will come some glare.

                    I guess I am going to be the differing viewpoint on this topic.

                    I have used Xenon Black Dot bulb Survivor flashlights for over 20 years. In fact the last new flashlight I bought was a Xenon Black Dot bulb Survivor. I chose that over an LED Survivor because of my experience of working with a fellow instructor in the burn tower with an LED Survivor. What WD6956 says is absolutely true about the LED Survivor the light is MUCH brighter and it does create that brights in the fog effect that to me makes it much more difficult to see in smoke. The Xenon Black Dot bulb Survivor does not have that brightness so it does not create as much of the brights in the fog effect.

                    If the purpose of the flashlight is to BE SEEN and not to see in smoke then the LED is probably a better choice. If the purpose of the flashlight is to see in smoke then I will take the Xenon bulb. None of them works all that good but I prefer a more focused less glare casting flashlight.

                    I will say I believe Streamlights decision to stop making the Xenon Black Dot bulb version of the Streamlight xl90 is a bad one. I guess if my Survivor ever takes a dump I will have to look elsewhere for a new flashlight.

                    My best advice for finding a flashlight you will like is to see if anyone you know is using one you are thinking about buying and see if they will let you try it out in smoke.

                      Vulacan Light

                      If I was you I would purchase a LED right angle Streamlight for your coat. I would also purchase a Streamlight Vulcan. At work I have a right angle on my coat, and the Vulcan on my gut belt. The Vulcan comes with a quick release seat belt strap so you can carry it on a gut belt or shoulder strap. The Vulcan cuts through smoke very well...

                        Thats the best advice so far. Get your hands on an LED and a halogen, or incadescant bulb, and see what works best for YOU
